2 HARDWARE OVERVIEW

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

2.1 Ports, Buttons, and Switches

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Modem Signal Strength: The bar LEDs indicate the signal strength from the active 3G/4G modem (CradlePoint

business-grade modem or USB/ExpressCard modem). Pushing this button toggles the display on and off. The signal

strength is shown for 10 seconds if the modem does not support concurrent data connection and signal strength

measurement. A blinking LED indicates ½ bar.

LAN Port: The CBA750B has one Ethernet port for a local network connection. Use this for connectivity and also for

Power-over-Ethernet (optional).

Power On/Off:

• I = On

• O = Off

DC Power Port: Attach the included power supply.

Reset: Return your CBA750B to factory default settings by pressing and holding the Reset button. This button is

recessed, so it requires a pointed object such as a paper clip to press. Press and hold for 10 seconds to initiate reset. This

erases configuration changes and resets the administrator password to the Default Password found on the product label.

USB/ExpressCard Modem Ports: The CBA750B has two USB 2.0 ports and one ExpressCard port.

Router/Passthrough Switch:

• I = Passthrough mode – Forces complete IP passthrough configuration.

• O = Router mode – Allows normal configuration options for the router.

The CBA750B ships with the Router/Passthrough Switch set to IP passthrough mode. In IP passthrough mode, all

of the following settings are pushed to the router:

• Load balance is disabled; the highest priority WAN device is used.

• The Routing Mode is set to IP Passthrough. (Network Settings → Local Networks in the “Local Network Editor”

under “IP Settings”)

• The Subnet Selection Mode is set to “Automatically Create Subnet”. (Network Settings → Local Networks in the

“Local Network Editor” under “IP Settings” – shows when IP Passthrough is set as the Routing Mode)

• If you have created secondary networks, they are disabled: only the primary LAN is enabled.

information about using the First Time Setup

Wizard.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

3.3 Common Problems

This section contains some of the most common issues faced by users of the CBA750B.

Please visit CradlePoint Knowledge Base at http://knowledgebase.cradlepoint.com/ for more help and answers to your

other questions.

3.3.1 You Cannot Connect to the Internet with a CradlePoint business-grade modem

Make sure that you have an active data plan and that your modem has been activated. A wireless broadband data plan

must be added to your business-grade modem. Wireless broadband data plans are available from wireless carriers such

as Verizon, AT&T, and Sprint. A new line of service can be added or a data plan can be transferred from an existing

account. You will need the ESN number (or SIM/IMEI number depending on your carrier plan) from the product label on

your modem to add or transfer a line of service.

After adding a data plan to the modem, you may need to activate the modem:

1. Log in to the CBA750B administration pages (see Accessing the Administration Pages).

2. Select Internet from the top navigation bar and Modem Settings from the dropdown menu (Internet → Modem

Settings).

3. Find and select the CradlePoint modem.

4. Click Update/Activate.

5. Click Activate in the popup.

Finally, if you have an active data plan and you have already activated your modem, you may be out of range of your

service provider. Check your signal strength in the Internet section of the Dashboard (Status → Dashboard). If you have

a weak signal in your location, contact your service provider.

If you are still not online after activating the modem, call CradlePoint Technical Support for further assistance.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

3.3.2 Your USB or ExpressCard Modem Does Not Work With the Router

• If your USB or ExpressCard modem is not working with the router, check the list of supported devices at

http://www.cradlepoint.com/modems to ensure you are using a supported device and carrier. The device you are

using must be supported on the carrier network providing your cellular service or it’s considered an unsupported

device, even if it is supported on another carrier’s network.

• Sometimes a USB data modem needs to be updated or have other configurations set correctly in order to make a

connection through the router. If your USB Modem has not been updated recently, it is recommended that you do

so if it is having trouble connecting to the CBA750B. Insert your USB data modem into your PC and access the

Internet using the software provided by your cellular carrier. Follow the directions provided to complete the update.

Once you have updated your USB data modem, reconnect the cellular device to your CradlePoint router and

connect to the Internet.

• If you are using a WiMAX modem, you need to set the WiMAX Realm. This can be done in the administration

pages. Log in using the hostname “cp/” or IP address “http://192.168.0.1” in your browser. Go to Internet →

Connection Manager. In the WAN Interfaces section, select your modem and click “Edit.” Select the WiMAX

Settings tab and select/input your WiMAX Realm.

• Some wireless carriers provide more than one Access Point Name (APN) that a modem can connect to. If you wish

to specify the APN, this can be done on the administration pages. Log in using the hostname “cp/” or IP address

“http://192.168.0.1” in your browser. Go to Internet → Connection Manager. In the WAN Interfaces section,

select your modem and click “Edit.” Select the SIM/APN Settings tab. There is an Access Point Name field: Set

the APN and click Submit. Some APN examples are isp.cingular, ecp.tmobile.com, and vpn.com. The modem

must be removed and reinserted (or the router must be rebooted) for this change to take effect.

• If the above issues have been resolved and you can connect to the router but you cannot get Internet through it

using your modem, you may need to upgrade the router firmware. Use your computer (you may need to plug your

modem directly into your computer if you don’t have another way to access the Internet) to download the latest

firmware for the router at http://www.cradlepoint.com/firmware/CBA750B. Then log into the router administration

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

pages and manually upload the firmware. Go to System Settings → System Software and click on “Manual

Firmware Upload”.

If you are still unable to access the Internet after following the above directions, contact CradlePoint Technical Support for

further assistance.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

4 WEB INTERFACE -- ESSENTIALS

The CBA750B has a Web interface for configuration and administration of all features. The interface is organized with 5

tabs at the top of the screen:

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

4.1 Administrator Login

To access the administration pages, open a Web browser and type the hostname “cp/” or IP address “http://192.168.0.1”

into the address bar. The Administrator Login page will appear.

Log in using your administrator password. Initially, this password can be found on the bottom of the CBA750B unit as the

Default Password. This password is also the last eight digits of the unit’s MAC address.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

You may have changed the administrator password during initial setup using the First Time Setup Wizard. Log in using

your personalized administrator password.

If you have forgotten your personalized password, you can reset the CBA750B to factory defaults. When you reset the

router, the administrator password will revert back to the Default Password. Press and hold the reset button on the

router unit until the lights flash (approximately 10-15 seconds). You can then log in using the Default Password.

4.1.1 Router Details

The Administrator Login page includes a quick-reference section that shows the following information:

Router Details

• Model Number: CBA750B

• Internet Connection: Connected/Disconnected

Modem Details

• Manufacturer: The name of the modem manufacturer (CradlePoint, Novatel, etc.).

• Model: The name of the modem model.

• Signal: The strength of the signal (dBm).

• Mode: (LTE, EVDO, HSPA, etc.)

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

4.2 Getting Started – First Time Setup

The First Time Setup Wizard will help you configure your APN and failure check settings and change your administrator

password to something you choose.

1) Open a browser window and type “cp/” or

“192.168.0.1” into the address bar. Press

enter/return.

2) When prompted for your password, type the eight

character Default Password found on the product

label on the bottom of the CBA750B (this is also the

last 8 digits of the router’s MAC address).

3) When you log in for the first time, you will be

automatically directed to the FIRST TIME SETUP

WIZARD. (Otherwise, go to Getting Started → First

Time Setup).

4) CradlePoint recommends that you change the

router’s ADMINISTRATOR PASSWORD, which is

used to log in to the administration pages.

5) You can select your TIME ZONE from a dropdown list. (This may be necessary to properly show time in your router

log, but typically your router will automatically determine your time zone through your browser.) Click NEXT.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6) Configuring Your Access Point Name (APN):

If you are using a SIM-based modem (LTE/GSM/HSPA) with your CradlePoint router, you may need to configure the

APN before it will properly connect to your carrier. Wireless carriers offer several APNs, so check with your carrier to

confirm the appropriate one to use. Some examples include:

• AT&T: "broadband"

• T-Mobile: "epc.tmobile.com"

• Rogers LTE: "lteinternet.apn"

• Bell: "inet.bell.ca"

• TELUS: "isp.telus.com"

You can either leave this on the Default setting

or select Manual and input a specific APN.

If your specific modem or SIM already has APNs

programmed into it, you should leave this on the

Default setting. After finishing this Wizard go to Internet → Connection Manager, select your modem, and edit the

settings. The SIM PIN/APN tab has more available settings than are provided here.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

7) Modem Authentication:

Some modems require a username and password to be entered to authenticate with a carrier. Do not fill in these fields

unless you are sure your modem needs authentication.

• Authentication Protocol – Set this only if your service provider requires a specific protocol and the Auto

option chooses the wrong one. Select from:

o Auto

o Pap

o Chap

• Username

• Password

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

8) Configuring Failure Check:

It is possible for a WAN interface to go down without the router recognizing the failure. (For example: the carrier for a

cellular modem goes dormant.) Enable Failure Check to ensure that you can get out to the Internet via your primary

WAN connection. This option is disabled by default because it may use data unnecessarily. Use this in combination

with failover or Aggressive Reset (Internet → Connection Manager under Modem Settings in the interface/rule

editor).

Idle Check Interval: Set the number of

seconds the router will wait between

checks to see if the WAN is still

available. (Default: 30 seconds. Range:

10-3600 seconds.)

Monitor while connected: Select from

the dropdown menu. (Default: Off)

• Active Ping: A ping request will

be sent to the Ping Target. If no

data is received, the ping request

will be retried 4 times at 5-second

intervals. If still no data is

received, the device will be disconnected and failover will occur. When “Active Ping” is selected, the next line

gives an estimate of data usage in this form: “Active Ping could use as much as 9.3 MB of data per month.”

This amount depends on the Idle Check Interval.

• Off: Once the link is established the router takes no action to verify that it is still up.

Ping IP Address: If you selected “Active Ping”, you will need to input an IP address that will respond to a ping request.

This IP address must be an address that can be reached through your WAN connection. Some ISPs/Carriers block

certain addresses, so choose an address that all of your WAN connections can use. For best results, select an

established public IP address. For example, you might ping Google Public DNS at 8.8.8.8 or Level 3 Communications at 4.2.2.2.

Click NEXT.

up a rule to track how much data you are using per month on a modem (Data Usage) or set the APN for a modem

(Connection Manager).

System Settings – Provides broad administrative controls. For example, you can upgrade firmware (System Software),

or enable remote management of the router (Administration).

4.4.1 Network Settings vs. Internet

When using the Web interface, it will be important to pay attention to the difference between the Internet source for your

CBA750B and the network created by the CBA750B. The “Internet” tab broadly refers to the router’s source of Internet,

while the “Network Settings” tab broadly refers to the network created by the router.

Internet tab Network Settings tab

Internet “input”

Source for CBA750B

WAN (Wide Area Network)

Internet “output”

Network created by CBA750B

LAN (Local Area Network)

Examples:

• If you want to change the content filtering settings for the network created by the CBA750B, go to the Network

Settings tab.

• If you want to track the data usage for your Internet source (such as your CradlePoint business-grade modem), go

to the Internet tab.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

4.6 IP Passthrough Setup

The CBA750B’s IP passthrough function takes the IP address of the attached modem and passes it through to the LAN.

By default, the CBA750B is configured for IP passthrough – the device ships with the ROUTER/PASSTHROUGH

SWITCH set to the I position (“O” is router mode; “I” is passthrough mode). Using IP passthrough disables some of the

device’s other router functionality.

There are three methods for setting up IP passthrough:

1) The ROUTER/PASSTHROUGH SWITCH on the device itself is set to “I”.

This forces a complete IP passthrough configuration with the following settings:

• Load balance is disabled; the highest priority WAN device is used.

• The Routing Mode is set to IP Passthrough. (Network Settings → Local Networks in the “Local Network

Editor” under “IP Settings”)

• The Subnet Selection Mode will be set to "Automatically Create Subnet". (Network Settings → Local

Networks in the “Local Network Editor” under “IP Settings” – this shows once IP Passthrough is set as the

Routing Mode.) You have the option to override this and select Force 24 Subnet, which forces a subnet of

255.255.255.0 and uses the first available address in the network as the gateway. This is for compatibility with

equipment that may not handle modem addressing schemes and should not be used unless necessary.

• If you have created secondary networks, they are disabled; only the primary LAN is enabled.

2) In the administration pages, select Getting Started → IP Passthrough Setup. This wizard will force an IP

passthrough configuration that matches the ROUTER/PASSTHROUGH SWITCH settings shown above. Simply read

through the wizard and select Enable IP Passthrough on the second page.

3) For custom configuration, manually input IP passthrough settings in the administration pages (this is the preferred

method for network professionals). Go to Network Settings → Local Networks for most of these changes.

Depending on your settings, you may need to go to other pages as well (e.g. you may need to disable load balancing).

Changes in the administration pages can overrule the switch setting, AND vice versa (i.e. the most recent setting changes

are implemented, regardless of method). In the administration pages you can set the device to ignore changes to the

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

router/passthrough switch. This option is listed in System Settings → Administration under the “Local Management”

tab. Click on the “Disable IP Passthrough/Configuration mode switch” option.

5.7 System Logs

The router automatically logs (records) events of possible interest in its internal memory. If there is not enough internal

memory for all events, logs of older events are deleted, but logs of the latest events are retained. The log options allow

you to filter the router logs so you can easily find relevant messages. This router also has external Syslog Server support

so you can send the log files to a computer on your network that is running a Syslog utility.

Auto Update: The logs automatically refresh whenever

the router creates a new message.

Update: Click to check for new router messages.

Clear Log: Clear the log file.

Save Log: This will open a dialog in your browser that

will allow you to save the router's log to your computer.

Search: Enter keywords to find specific events.

Level: Select/Deselect from the following levels to filter

messages by priority.

• Critical

• Error

6 NETWORK SETTINGS

The Network Settings tab provides access to 7 submenu options for administering the following functions/tasks. These

functions are all related to controlling the LAN (Local Area Networks), the networks you set up with the CBA750B.

• Content Filtering

• DHCP Server

• DNS

• Firewall

• Local Networks

• MAC Filter / Logging

• Routing

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.1 Content Filtering

You have two main options for filtering content in a network created by your router.

1) Network WebFilter Rules: Create a list of websites that will be either disallowed or allowed. Customize the filter

settings for each network. (These rules will not block HTTPS websites.)

2) OpenDNS Content Filtering: Allows several options for filtering rules using OpenDNS, a third party service.

6.1.1 Network WebFilter Rules

Network WebFilter Rules allow you to control access from your network to external domains or websites. Rules are

assigned to a specific LAN network (or all networks). The highest priority rule will have precedence when there is a

conflict. Addresses can be added by URL/Domain name or by IP address.

Exceptions to existing rules can be created by adding another rule with higher priority. For example, if access to

espn.go.com is desired but go.com is blocked with a priority of 50, the addition of an “Allow” rule for espn.go.com with a

priority of 51 or greater will allow access.

When creating rules keep in mind that some sites use multiple domains, so each domain may need a rule added to

produce the desired behavior.

NOTE: Websites that use HTTPS will not be blocked by these rules. You will need to use OpenDNS to block HTTPS websites.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Click Add or Edit to open the Filter Rule Editor.

• Assigned Network: Select either “All Networks” or one of

your LAN networks from the dropdown list.

• Domain/URL/IP: Enter the Domain Name or URL (address)

of the website you wish to control access for, e.g.

www.google.com. To make sure the full domain is

blocked, enter the most inclusive domain (e.g. google.com

will effectively block www.google.com as well as

maps.google.com and images.google.com). Alternatively

you can use an IP address, e.g. 8.8.8.8, or address range

written in CIDR notation, e.g. 8.8.8.0/24.

• Filter Action: Select Block or Allow.

• Rule Priority: Higher number rules overrule lower number

rules.

• Enabled: A rule can be enabled or disabled by selecting or

deselecting the checkbox.

Click Submit to save your rule changes.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.1.2 Default Filter Settings

Use Default Network Filter Settings together with Network WebFilter Rules to control website access. All of your

networks are set to allow website access by default. Select a network and click Edit to change the default filter settings.

Default Action: Select from the following dropdown options:

• Allow Access (default)

• Block Access

When a network is set to Allow Access, it will allow access to

sites not specifically blocked in the WebFilter Rules.

When a network is set to Block Access, it will block access to

sites not specifically allowed in the WebFilter Rules.

Filter URLs by IP Address: (Default: No) Changing this option to

“Yes” will cause the router to perform a DNS lookup on URL

entries, and the IP addresses will be appended to the appropriate

block/allow list. This can have the side effect of being very strict;

sites that are hosted across many domains may need every

domain added to the list for full functionality.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.1.3 Cloud Based Filtering/Security

Select a third-party Cloud Provider from the dropdown list.

• Disabled

• Umbrella by OpenDNS

Umbrella by OpenDNS

Umbrella by OpenDNS is a cloud-

based web filtering and security

solution that protects you online by

filtering websites. Go to

http://www.opendns.com/business-

security/ for information about

Umbrella.

Enter your Umbrella account

information in order to use these

content filtering settings.

OpenDNS ISP Filter Bypass

Algorithm: It is possible that your

Internet Service Provider (ISP) uses

the port that OpenDNS is configured

to access, port 53, which will prevent OpenDNS filtering. If OpenDNS does not appear to be working correctly, enabling

this will attempt to bypass those ports when using an OpenDNS content filtering level.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.2 DHCP Server

DHCP stands for Dynamic Host Configuration Protocol. The built-in DHCP server automatically assigns IP addresses to

the computers and other devices on each local area network (LAN). In this section you can view a list of assigned IP

addresses and reserve IP addresses for particular devices.

Active Leases: A list of devices that have

been provided DHCP leases. The DHCP

server automatically assigns these leases.

This list will not include any devices that

have static IP addresses on the network.

Select a device and click Reserve to add

the device and its IP address to the list of

Reservations.

Reservations: This is a list of devices with

reserved IP addresses. This reservation is

almost the same as when a device has a static IP address except that the device must still request an IP address from the

router. The router will provide the device the same IP address every time. DHCP reservations are helpful for server

computers on the local network that are hosting applications such as Web and FTP. Servers on your network should

either use a static IP address or a reservation.

While you have the option to manually input the information to reserve an IP address (Hostname, Hardware Addr, IP

Addr), it is much simpler to select a device under the Active Leases section and click “Reserve.” The selected device’s

information will automatically be added under Reservations.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.3 DNS

DNS, or Domain Name System, is a naming system that translates between domain names (www.cradlepoint.com, for

example) and Internet IP addresses (206.207.82.197). A DNS server acts as an Internet phone book, translating between

names that make sense to people and the more complex numerical identifiers. The DNS page for the CBA750B has these

distinct functions:

• DNS Settings: By default your router is set to automatically acquire DNS servers through your Internet provider

(Automatic). DNS Settings allows you to specify DNS servers of your choosing instead (Static).

• Dynamic DNS Configuration: Allows you to host a server (Web, FTP, etc.) using a domain name that you have

purchased (www.yourname.com) with your dynamically assigned IP address.

• Known Hosts Configuration: Allows you to map a name (printer, scanner, laptop, etc.) to an IP address of a

device on the network.

6.3.1 DNS Settings

You have the option to choose specific DNS servers for

your network instead of using the DNS servers assigned

by your Internet provider. The default DNS servers are

usually adequate. You may want to assign DNS servers if

the default DNS servers are performing poorly or if you

have a local DNS server on your network.

Automatic Config: Automatic or Static (default:

Automatic). Switching to “Static” enables you to set specific DNS servers in the Primary DNS and Secondary DNS fields.

Primary DNS and Secondary DNS: If you choose to specify your DNS servers, then enter the IP addresses of the

servers you want as your primary and secondary DNS servers in these fields. The DNS server settings will be pre-

populated with public DNS server IP addresses. You can override the IP address with any other DNS server IP address of

your choice. For example, Google Public DNS servers have the IP addresses 8.8.8.8 and 8.8.4.4 while 4.2.2.2 and 4.2.2.3

are servers from Level 3 Communications.

Force All DNS Requests To Router: Enabling this will redirect all DNS requests from LAN clients to the router's DNS

server. This will allow the router even more control over IP addresses even when clients have their own DNS servers

statically set.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.3.2 Dynamic DNS Configuration

The Dynamic DNS feature allows you to host a server (Web, FTP, etc.) using a domain name that you have purchased

(www.yourname.com) with your dynamically assigned IP address. Most broadband Internet Service Providers assign

dynamic (changing) IP addresses. When you use a Dynamic DNS service provider, you can enter your host name to

connect to your server, no matter what your IP address is.

Enable Dynamic DNS: Enable this option only if you

have purchased your own domain name and registered

with a Dynamic DNS service provider.

Server Type. Select a Dynamic DNS service provider

from the pull-down list:

• www.DynDNS.org

• www.DNSomatic.com

• www.ChangeIP.com

• www.NO-IP.com

• Custom Server (DynDNS clone)

Custom Server Address. Only available if you select

Custom Server from the Server Address dropdown list.

Enter your custom dynamic DNS server address here.

The server must support the Dynamic DNS protocol.

See www.dyndns.org for details. Example:

myserver.mydomain.net.

Use HTTPS: Use the more secure HTTPS protocol.

This is recommended, but could be disabled if not compatible with the server.

Host name: Enter your host name, fully qualified. For example: myhost.mydomain.net.

User name: Enter the user name or key provided by the Dynamic DNS service provider. If the Dynamic DNS provider

supplies only a key, enter that key for both the User name and Password fields.

Password: Enter the password or key provided by the Dynamic DNS service provider.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.3.3 Advanced Dynamic DNS Settings

Update period (hours). (Default: 576) The time between periodic updates to the Dynamic DNS if your dynamic IP

address has not changed. The timeout period is entered in hours so valid values are from 1 to 8760.

Override External IP. The external IP is usually configured automatically during connection. However, in situations where

the unit is within a private network behind a firewall or router, the network's external IP address will have to be manually

configured in this field.

You may find out what your external IP address is by going to http://myip.dnsomatic.com/ in a web browser.

6.3.4 Known Hosts Configuration

The Known Hosts Configuration feature allows you to

map a name (printer, scanner, laptop, etc.) to an IP

address of a device on the network. This assigns a new

hostname that can be used to conveniently identify a

device within the network, such as an office printer.

Click Add to name a device in your network.

Fill in the following fields:

• Hostname: Choose a name that is meaningful to you. No spaces

are allowed in this field.

• IP address: The address of the device within your network.

EXAMPLE: a personal laptop with IP address 192.168.0.164 could be assigned the

name “MyLaptop”.

Since the assigned name is mapped to an IP address, the device’s IP

address should not change. To ensure that the device keeps the same IP address, go to Network Settings → DHCP

Server and reserve the IP address for the device by selecting the device in the Active Leases list and clicking “Reserve”.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.4 Firewall

The router automatically provides a firewall. Unless you configure the router to the contrary, the router does not respond

to unsolicited incoming requests on any port, thereby making your LAN invisible to cyber attackers.

However, some network applications cannot run with a tight firewall. Those applications need to selectively open ports in

the firewall to function correctly. The options on this page control ways of opening the firewall to address the needs of

specific types of applications.

6.4.1 Port Forwarding Rules

A port forwarding rule allows traffic from the

Internet to reach a computer on the inside of your

network. For example, a port forwarding rule might

be used to run a Web server.

Exercise caution when adding new rules as

they impact the security of your network.

Click Add to create a new port forwarding rule, or select an

existing rule and click Edit.

Add/Edit Port Forwarding Rule

• Name: Name your rule.

• Use Port Range: Changes the selection options to allow

you to input a range of ports (if desired).

• Internet Port(s): The port number(s) as you want it

defined on the Internet. Typically these will be the same

as the local port numbers, but they do not have to be.

These numbers will be mapped to the local port numbers.

• Local Computer: Select the IP address of an attached

device from the dropdown menu, or manually input the IP address of a device.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

• Local Port(s): The port number(s) that corresponds to the service (Web server, FTP, etc) on a local computer or

device. For example, you might input “80” in the Local Port(s) field to open a port for a Web server on a computer

within your network. The Internet Port(s) field could then also be 80, or you could choose another port number that

will be used across the Internet to access your Web server. If you choose a number other than 80 for the Internet

Port, connections to that number will be mapped to 80—and therefore the Web server—within your network.

• Protocol: Select from the following options in the dropdown menu:

o TCP

o UDP

o TCP & UDP

• Click Submit to save your completed port forwarding rule.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.4.2 Network Prefix Translation (Advanced)

Network Prefix Translation is used in IPv6 networks to translate one IPv6 prefix to another. IPv6 prefix translation is an

experimental specification (RFC 6296) trying to achieve address independence similar to NAT in IPv4. Unlike NAT,

however, NPT is stateless and preserves the IPv6 principle that each device has a routable public address. But it still

breaks any protocol embedding IPv6 addresses (e.g. IPsec) and is generally not recommended for use by the IETF. NPT

can help to keep internal network ranges consistent across various IPv6 providers, but it cannot be used effectively in all

situations.

The primary purpose for CradlePoint’s NPT implementation is for failover/failback and load balancing setups. LAN clients

can potentially retain the original IPv6 lease information and may experience a more seamless transition when WAN

connectivity changes than if not utilizing NPT.

Mode:

• None – No translation is performed

• Load Balance Only – (Default) Only

translate networks when actively load

balancing

• First – Use the first IPv6 prefix found

• Static – Always use a static IPv6 translation (input the prefix here)

Transitioning from short prefix to a longer prefix (such as from /48 to /64) is not without problems, as some of the LANs

may lose IPv6 connectivity.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.4.3 IP Filter Rules (Advanced)

An "Incoming" IP filter rule restricts remote access

to computers on your local network. "Outgoing"

filter rules prevent computers on your local

network from initiating communication to the

address range specified in the rule.

This feature is especially useful when combined with port forwarding and/or DMZ to restrict remote access to a specified

host or network range. For example, in order to host a server you might have opened ports with a port forwarding rule that

could expose your LAN to cyber attacks. With an incoming IP filter rule, you can restrict the access to your LAN to only

known devices.

• Name: Name your rule.

• Enabled: Selected by default.

• Log: When checked each packet

matching this filter rule will be logged

in the System Logs.

• Action: “Allow” or “Deny”

• Protocol: Any, ICMP, TCP, UDP,

GRE, ESP, or SCTP.

IP Source / IP Destination

• IP Negation: Match on any IP

address that is NOT in the specified IP

network range.

• Network IP: Optional field to specify a

matching network IP address for this

rule to match against.

• Netmask: Use this to define a subnet

size this rule will match against.

• Port Negation: Match on any port

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

that is NOT in the specified port range.

• Port(s): Use for a single port or a range of ports. Fill in the left side for a single port.

Use Network IP, Netmask, and Port(s) to specify the ports and addresses for which the rule applies. You can specify a

range of ports or a single port. Similarly, the netmask can be used to define either a range of addresses (i.e.

255.255.255.0) or a single address (255.255.255.255).

If you leave these values blank, then all IP addresses and ports will be included. IP Source and IP Destination options

can be used to differentiate between the directions that packets go. You could permit packets to come from particular IP

addresses but then not allow packets to return to those addresses.

Example of an IP Filter Rule: Suppose you have opened a port in your firewall in order to run a server. Someone, Johnny, is abusing that

opening, so you would like to restrict his access. Create a rule that will deny Johnny’s IP address.

Add IP Filter Rule

• Name: No more Johnny

• Enabled: Selected

• Action: Deny

• Protocol: Any

IP Source

• Network IP: 172.22.24.160 (Johnny’s IP address)

• Netmask: 255.255.255.255 (This netmask restricts the rule to one single address).

• Port(s): 80

6.4.4 DMZ: DeMilitarized Zone (Advanced)

A DMZ host is effectively not firewalled in the

sense that any computer on the Internet may

attempt to remotely access network services at the

DMZ IP address. Typical uses involve running a

public Web server or sharing files.

Input the IP Address of a single device in your

network to create a DeMilitarized Zone for that device. To ensure that the IP address of the selected device remains

consistent, go to the “Reservations” section under Network Settings → DHCP Server and reserve the IP address for the

device.

As with port forwarding, use caution when enabling the DMZ feature as it can threaten the security of your

network. Only use DMZ as a last resort.

6.4.5 Application Gateways (Advanced)

Enabling an application gateway makes pinholes

thru the firewall. This may be required for some

applications to function, or for an application to

improve functionality or add features.

Exercise caution in enabling application

gateways as they impact the security of your

network.

Enable any of the following types of application

gateways:

• PPTP: For virtual private network access

using Point to Point Tunneling Protocol. This

is enabled by default.

• SIP: For Voice over IP using Session Initiation Protocol.

• TFTP: Enables file transfer using Trivial File Transfer Protocol.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

• FTP: To allow normal mode when using File Transfer Protocol. This is not needed for passive mode. This is

enabled by default.

• IRC: For Direct Client to Client (DCC) transfer when using Internet Relay Chat. You may wish to forward TCP port

113 for incoming identd (RFC 1413) requests.

6.4.6 Firewall Options (Advanced)

Anti-Spoof: Anti-Spoof checks help protect against

malicious users faking the source address in

packets they transmit in order to either hide

themselves or to impersonate someone else. Once

the user has spoofed their address they can launch

a network attack without revealing the true source of the attack or attempt to gain access to network services that are

restricted to certain addresses.

6.4.7 Remote Administration Access Control

(Advanced)

Enable Remote Administration Access Control:

Selecting this option allows you to make remote

administration tools available to only the specified

IP addresses. Access from all other IP addresses

will be blocked. This option only filters IP

addresses: you must enable Remote Management

separately (System Settings → Administration).

The services affected by this include remote HTTP,

HTTPS, SNMP, and SSH configuration tools. This does not restrict access to LAN-based administration, i.e. devices

within your network still have administration access. The individual remote administration services can be enabled under

System Settings → Administration --> Remote Management.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Remote Administration Access Control Editor

IP Address: The IP address that will be allowed to access

administrative services through the WAN.

Netmask (Optional): The netmask allows you to specify

what IP address sets will be allowed access. If this field is

left empty a netmask of 255.255.255.255 will be used,

which means that only the single specified IP address

would have remote administration access.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.5 Local Networks

This section is used to configure the settings for networks created by your router. The user can set up multiple networks

on the CBA750B, each with its own unique configuration and its own selection of interfaces. Each local network can be

attached to either (or both) of the following types of interfaces:

• Ethernet

• VLAN

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.5.1 Local IP Networks

Local IP Networks displays the following information for each network:

• Network Name and IP address/Netmask (along the top bar)

• Enabled (Yes/No)

• DHCP Mode (e.g. DHCP Server mode)

• Schedule (Enabled/Disabled – See the

Schedule tab in the Local Network

Editor)

• IPv4 Routing Mode (NAT, Standard,

IP Passthrough, Disabled)

• IPv6 Addressing Mode (SLAAC Only,

SLAAC with DHCP, Disable SLAAC

and DHCP)

• Access Control (Admin Access, UPnP Gateway, LAN Isolation)

• Attached Interfaces (Ethernet port, VLAN)

Click Add to configure a new network, or select an existing network and click Edit to view configuration options.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.5.2 Local Network Editor

Click Add or select a network and click Edit to open the Local Network Editor to make configure a LAN. The Local

Network Editor contains the following tabs: General Settings, IPv4 Settings, IPv6 Settings, Interfaces, Access Control,

IPv4 DHCP, IPv6 Addressing, and Schedule.

General Settings:

Enabled: Push to manually disable a network. Also,

some settings could cause a network to be

automatically disabled: click here to re-enable the

network.

Name: This primarily helps to identify this network

during other administration tasks.

Hostname: [Default: cp (for CradlePoint)] The

hostname is the DNS name associated with the

router's local area network IP address.

NOTE: You can access the router’s administration pages by

typing the hostname into your browser, so if you change “cp” to

another hostname, you can access the administration pages

through the new hostname.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

IPv4 Settings:

IP Address: This is the address used by the router for local area network communication. Changes to this parameter may

require a restart to computers on this network.

Each network must have a distinct IP address. Most users

will want an address from one of the following private IP

ranges:

• 10.0.0.1 - 10.255.255.1

• 172.16.0.1 - 172.31.255.1

• 192.168.0.1 - 192.168.255.1

NOTE: The final number does not have to be 1, but it is a simple,

logical convention for routers that leaves higher numbers free for

other devices.

Netmask: (Default: 255.255.255.0) The netmask controls

how many IP addresses can be used in this network. The

default value allows for 254 IP addresses.

IPv4 Routing Mode: (Default: NAT) Each network can

use a unique routing mode to connect to the Internet and

other local networks. NAT is desirable for most

configurations. Select from the following options in the

dropdown list:

• NAT: Network Address Translation hides private IP addresses behind the router's IP address. This is the simplest

and most common choice for users, because NAT does the translation work for you.

• Standard: NAT-less routing. If you select Standard, you must separately configure your IP addresses so that they

will be publically accessible. Typically you will not select this option unless you have a specific reason to bypass

NAT.

• IP Passthrough: IP Passthrough passes the IP address given by a cellular modem (WAN) through the router to

Ethernet (LAN). The easiest way to enable IP Passthrough mode is with the IP Passthrough Setup Wizard (see

Getting Started → IP Passthrough Setup).

• Disabled: Disable this network.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

IPv6 Settings:

IPv6 must be enabled through the WAN initially: go to

Internet → Connection Manager to enable IPv6.

IPv6 Address Source: By default, this is set to

Delegated, which means the IPv6 address range for

the LAN is passed through from the WAN side. Change

this to Static to input your own IPv6 address range

here, or select None to explicitly disable IPv6 LAN

connectivity.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Interfaces:

Select network interfaces to attach to this network. Choose from the Ethernet port and VLAN interfaces. Double-click on

an interface shown on the left in the Available section to move them to the Selected section on the right (or highlight an

interface and click the “+” button). To deselect an interface, double-click on an interface in the Selected section (or

highlight the interface and click the “–“ button).

If you want more interface options, you must configure additional interfaces separately. See the Local Network

Interfaces section below (on this same administration page: Network Settings → Local Networks).

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Access Control:

Tune the access control settings of this network to match the intended use. Simply select or deselect any of the following:

• LAN Isolation: When checked, this network will

NOT be allowed to communicate with other local

networks.

• UPnP Gateway: Select the UPnP (Universal

Plug and Play) option if you want to enable the

UPnP Gateway service for computers on this

network.

• Admin Access: When enabled, users may

access these administration pages on this

network.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

IPv4 DHCP:

Changing settings for the IPv4 DHCP server is optional. The default selections are almost always sufficient.

DHCP Server: (Default: Enabled) When the DHCP server is enabled, users of your network will be able to automatically

connect to the Internet without any special configuration. It is recommended that you leave this enabled. Disabling the

DHCP server is only recommended if you have another DHCP server on your network and it is configured properly.

Range Start and Range End: These designate the range of values in the reserved pool of IP addresses for the DHCP

server. Values within this range will be given to any DHCP enabled computers on your network. The default values are

almost always sufficient (default: 72 to 200, as in 192.168.0.72 to 192.168.0.200).

Example: The router uses an IP address of 192.168.0.1 for its primary network by default. A computer designated as a Web server has a static IP

address of 192.168.0.3. Another computer is designated as an FTP server with a static IP address of 192.168.0.4. The starting IP address for the

DHCP server needs to be 192.168.0.5 or higher.

Lease Time: [Default: 720 minutes (12 hours)] The lease time specifies how long DHCP-enabled computers will wait

before requesting a new DHCP lease. Smaller values are better suited to busy environments.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Custom Options: Input a custom DHCP option by first clicking the Custom Options field to enable it and then clicking

“Add” at the top of the table that appears. There are close to 200 possible DHCP options available. One of the more

common uses is to assign a VoIP phone server using option 66 (Server name).

• Option: Select an option from the dropdown list or

manually enter the number of an option. A complete list of

options is available from IANA.

• Value: Generally this field should be a string, IP address,

or numeric value. Some fields can accept both IP

addresses and hostnames – in these cases you may need

to wrap this value in quotes. For example, option 66

(Server name) requires quotes around IP addresses.

DHCP Relay: DHCP Relay communicates with a DHCP server

and acts as a proxy for DHCP broadcast messages that must be

routed to remote segments. This is accomplished by converting broadcast DHCP messages to unicast messages to

communicate between clients and servers.

DHCP Server Address: An optional DHCP server address if more than one DHCP server is located on the network. This

field is only available when DHCP Relay is enabled.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

IPv6 Addressing:

Address Configuration Mode:

SLAAC Only – SLAAC stands for stateless address

autoconfiguration. The router regularly generates a

router advertisement that includes network prefix and

routing information, allowing clients to autogenerate an

address and start communicating on the network. Clients

utilize neighbor discovery protocols to ensure multiple

clients on the subnet have not chosen an identical

address.

SLAAC with DHCP – (Default) IPv6 DHCP provides an

additional client configuration method and is regularly

combined with SLAAC to provide DNS servers (a

shortcoming in the original SLAAC specification) and

additional options not supported by SLAAC. By

defaulting to SLAAC with DHCPv6, all IPv6-capable

clients on the network should be configurable with IPv6

connectivity.

• DHCP Range Start: The beginning of the range that will be used for IPV6 DHCP addresses. The IPv6 range will

always start at 1.

• DHCP Range End: The ending IP address in the DHCP Server range is the end of the reserved pool of IP

addresses that will be given to any DHCP-enabled computers on your network.

• IPv6 DHCP Lease Time: This specifies how long DHCP-enabled computers will wait before requesting a new

DHCP lease.

Disable SLAAC and DHCP – Disable both IPv6 address configuration modes.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Schedule:

Set up a schedule for this network interface. This allows an interface to be enabled or disabled during specific hours of a

day. For example, use this to limit the network to business hours.

Schedule Service: (Default: Disabled.)

Select to enable. This will open a

configurable chart for setting the

schedule.

Each hour of the week is represented by a

black or gray square. Black represents

disabled, while gray represents enabled.

Hover over a square to reveal the hour it

represents. Click on the squares to toggle

between black and gray.

In the example shown, the network is

enabled from 8-5 on Monday through

Friday, but disabled at all other times.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.5.3 Local Network Interfaces

Each LAN type—Ethernet and VLAN—has a separate section with configuration options. Unless the default configuration

is sufficient, YOU MUST CONFIGURE EACH INTERFACE SEPARATELY in order to create the desired interface options

for a network. You can then select these interfaces to add to a network in the Local Network Editor (see above).

Select from the following tabs:

• Ethernet Port Configuration

• VLAN Interfaces

Ethernet Port Configuration

Ethernet Port Configuration provides controls for your router’s Ethernet port. While default settings will be sufficient in

most circumstances, you have the ability to control the Link Speed. Additional controls for WAN ports are available in

Internet → Ethernet Settings.

Link Speed: Default setting is Auto. The Auto setting is preferred in most cases.

• Auto

• 10Mbps - Half Duplex

• 10Mbps - Full Duplex

• 100Mbps - Half Duplex

• 100Mbps - Full Duplex

• 1000Mbps - Full Duplex

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Ethernet Port Group Editor

A Port Group represents a logical grouping of Ethernet ports. Any

computers physically connected to ports in a group will be allowed to

freely communicate with each other.

Since the CBA750B has only 1 Ethernet port, this feature will rarely

be necessary. The only use is to switch the port to a different local

network.

NOTE: You must separately ensure that this logical interface is attached to a Local

IP Network in the top panel of this page.

Port Group ID: The Group ID field provides a reference to this port

group to be used in other parts of the router configuration. For

example, this ID is referenced in the Local IP Networks configuration

to attach this group of Ethernet port group with a network

configuration. Use a simple short text phrase to describe a group,

such as "main", "guestport", etc.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

VLAN Interfaces

A virtual local area network, or VLAN,

functions as any other physical LAN, but it

enables computers and other devices to be

grouped together even if they are not

physically attached to the same network

switch.

To enable a VLAN, select a VID (virtual LAN ID) and an Ethernet port group through which users can access the VLAN.

Then go back up to the Local Network Editor to attach your new VLAN to a network. To use a VLAN, the VID must be

shared with another router or similar device so that multiple physical networks have access to the one virtual network.

Click Add to create a new VLAN interface.

VLAN Editor

VID: An integer value that is the Virtual LAN ID.

Ethernet Group: Select the LAN port with which you want

to associate the VLAN ID from a dropdown list.

Click Submit to save your configured VLAN.

6.6 MAC Filter / Logging

A MAC (Media Access Control) address is a unique identifier for a computer or other device. This page allows you to

manage clients by MAC address. You can filter clients by MAC addresses and/or keep a log of devices connected to your

router.

6.6.1 Filter Configuration

The MAC Filter allows you to create a

list of devices that have either

exclusive access (whitelist) or no

access (blacklist) to your LAN.

Enabled: Click to allow MAC Filter

options.

Whitelist: Select either “Whitelist” or

“Blacklist” from a dropdown menu. In

"Whitelist" mode, the router will

restrict access to all computers except

those contained in the "MAC Filter

List" panel. In “Blacklist” mode, listed devices are completely blocked.

MAC Filter List (Whitelist or Blacklist): Add devices to either your whitelist or blacklist simply by inputting each device’s

MAC address.

NOTE: Use caution when using the MAC Filter to avoid accidentally blocking yourself from accessing the router.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.6.2 MAC Logging Configuration

Enable MAC Logging: Enabling MAC Logging will cause the router to log MAC addresses that are connected to the

router. MAC addresses that you do not want to have logged (addresses that you expect to be connected) should be

added to the “Ignored MAC Addresses” list.

You can configure the router to send an alert if a connected device has a MAC address that the router doesn’t recognize.

Go to System Settings → Device Alerts to set up these email alerts.

Ignored MAC Addresses: This is the

list of MAC addresses that will not

produce an alert or a log entry when

they are connected to the router.

These should be MAC addresses that

you expect to be connected to the

router.

To add MAC addresses to this list,

simply select devices shown in the

MAC Address Log and click “Ignore.”

You can also add addresses

manually.

MAC Address Log: This shows the

last 64 MAC addresses that have

connected to the router, as well as

which interface was used to connect.

The time/date that is logged is the time of the first connection. The page may need to be refreshed to show the most

recent log entries.

Double-clicking on entries from this list will add them to the Ignored MAC Addresses list.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6.7 Routing

Add a new static route to the IP routing table or edit/remove an existing route.

Static routes are used in networks with more than one layer, such as when there is a network within a network so that

packet destinations are hidden behind an additional router. Adding a static route is a way of telling the router about an

additional step that packets will need to take to reach their destination.

Click Add to create a new static route.

IP/Network Address: The IP address of the target

network or host.

Netmask: The Netmask, along with the IP address, defines the network the computer belongs to and which other IP

addresses the computer can see in the same LAN. An IP address of 192.168.0.1 along with a Netmask of 255.255.255.0

defines a network with 256 available IP addresses from 192.168.0.0 to 192.168.0.255.

NOTE: 255.255.255.255 is used to signify only the host that was

entered in the IP/Network Address field.

Gateway: Specifies the next hop to be taken if this route is

used. A gateway of 0.0.0.0 implies there is no next hop,

and the IP address matched is directly connected to the

router on the interface specified: LAN or WAN.

Allow Network Access: (Default: Deselected.) Some

static routes will need an IP Filter Rule via the Firewall to

allow packets through the route without being blocked.

Selecting this option automatically creates this IP Filter

Rule. If the IP/Network Address falls outside the LAN IP

range, you probably need to select this option.

7 INTERNET

The Internet tab provides access to 3 submenu items for managing a variety of Internet connection options.

• Connection Manager

• Data Usage

• WAN Affinity / Load

Balancing

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

7.1 Connection Manager

The router can establish an uplink via any modems plugged into a modem port. If there is more than one modem attached

and the primary connection fails, the router will automatically attempt to bring up a new link on another device. This

feature is called failover. If Load Balance is enabled, multiple WAN devices establish a link at the same time.

7.1.1 WAN Interfaces

This is a list of the available interfaces used to access

the Internet. You can enable, stop, or start devices from

this section. By using the priority arrows (the arrows in

the boxes to the left—these show if you have more than

one available interface), you can set the interface the

router uses by default and the order that it allows

failover.

Load Balance: If this is enabled, the router will use multiple WAN interfaces to increase the data transfer throughput by

using any connected WAN interface consecutively. Selecting Load Balance will automatically start the WAN interface and

add it to the pool of WAN interfaces to use for data transfer. Turning off Load Balance for an active WAN interface may

require the user to restart a current browsing session.

Enabled: Selected by default. Deselect to disable an interface.

Click on the small box at the top of the list to select/deselect all devices for either Load Balance or Enabled.

Click on a device in the list to reveal additional information about that device and to enable configuration options.

• Uptime

Click “Edit” to view configuration options for the selected device. Click “Control” to view options to activate or update the

device.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

7.1.3 General Settings

• Enabled: Select/deselect to

enable/disable.

• Force NAT: Normally the LAN Route

Mode controls the use of NAT

(network address translation). When

this option is selected the router will

always perform NAT when traffic is

sent out from this device.

• Priority: This number controls failover

and failback order. The lower the

number, the higher the priority and the

more use the device will get. This

number will change when you move

devices around with the priority arrows

in the WAN Interfaces list.

• Load Balance: Select to allow this

device to be available for the Load

Balance pool.

• Download bandwidth: Defines the

default download bandwidth for use in

Load Balance algorithms. (Range: 128

Kb/s to 76800 Kb/s.)

• MTU: Maximum transmission unit. This is the size of the largest protocol data unit that the device can pass.

(Range: 46 to 1500 Bytes.)

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

IPv4 Failure Check (Advanced)

If this is enabled, the router will check that the

highest priority active WAN interface can get

to the Internet even if the WAN connection is

not actively being used. If the interface goes

down, the router will switch to the next highest

priority interface available. If this is not

selected, the router will still failover to the next

highest priority interface but only after the

user has attempted to get out to the Internet and failed.

Idle Check Interval: The amount of time between each check. (Default: 30 seconds. Range: 10-3600 seconds.)

Monitor while connected: (Default: Off) Select from the following dropdown options:

• Passive DNS (modem only): The router will take no action until data is detected that is destined for the WAN.

When this data is detected, the data will be sent and the router will check for received data for 2 seconds. If no data

is received the router behaves as described below under Active DNS.

• Active DNS (modem only): A DNS request will be sent to the DNS servers. If no data is received, the DNS

request will be retried 4 times at 5-second intervals. (The first 2 requests will be directed at the Primary DNS server

and the second 2 requests will be directed at the Secondary DNS server.) If still no data is received, the device will

be disconnected and failover will occur.

• Active Ping: A ping request will be sent to the Ping Target. If no data is received, the ping request will be retried 4

times at 5-second intervals. If still no data is received, the device will be disconnected and failover will occur. When

“Active Ping” is selected, the next line gives an estimate of data usage in this form: “Active Ping could use as much

as 9.3 MB of data per month.” This amount depends on the Idle Check Interval.

• Off: Once the link is established the router takes no action to verify that it is still up.

Ping IP Address: If you selected “Active Ping”, you will need to input an IP address. This must be an address that can be

reached through your WAN connection (modem/Ethernet). Some ISPs/Carriers block certain addresses, so choose an

address that all of your WAN connections can use. For best results, select an established public IP address.

For example, you might ping Google Public DNS at 8.8.8.8 or Level 3 Communications at 4.2.2.2.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

IPv6 Failure Check (Advanced)

These settings match IPv4 Failure Check; the only

difference in the UI is that the ping address uses IPv6.

Failback Configuration (Advanced)

This is used to configure failback, which is the ability to go back to a higher priority WAN interface if it regains connection

to its network.

Usage: Fail back based on the amount of data passed

over time. This is a good setting for when you have a

dual-mode EVDO/WiMAX modem and you are going in

and out of WiMAX coverage. If the router has failed over

to EVDO it will wait until you have low data usage before

bringing down the EVDO connection to check if a WiMAX

connection can be made.

• High (Rate: 80 KB/s. Time Period: 30 seconds.)

• Normal (Rate: 20 KB/s. Time Period: 90 seconds.)

• Low (Rate: 10 KB/s. Time Period: 240 seconds.)

• Custom (Rate range: 1-100 KB/s. Time Period range: 10-300 seconds.)

Time: Fail back only after a set period of time. (Default: 90 seconds. Range: 10-300 seconds.) This ensures that the

higher priority interface has remained online for a set period of time before it becomes active (in case the connection is

dropping in and out, for example).

Disabled: Deactivate failback mode.

Immediate Mode: Fail back immediately whenever a higher priority interface is plugged in or when there is a priority

change. Immediate failback returns you to the use of your preferred Internet source more quickly which may have

advantages such as reducing the cost of a failover data plan, but it may cause more interruptions in your network than

Usage or Time modes.

7.1.4 IP Overrides

IP overrides allow you to override IP settings after a device’s IP settings have been configured. Only the fields that are

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

7.1.5 IPv6 Settings

The IPv6 (http://en.wikipedia.org/wiki/IPv6) configuration allows you to enable and configure IPv6 for a WAN device.

These settings should be configured in combination with the IPv6 LAN settings (go to Network Settings → Local

Networks, select the LAN under Local IP Networks, and click Edit) to achieve the desired result.

This is a dual-stacked implementation of IPv6, so IPv6 and IPv4 are used alongside each other. If you enable IPv6, the

router will not allow connections via IPv4. When IPv6 is enabled, some router features are no longer supported. These

are:

• RADIUS/TACACS+ accounting for wireless clients and admin/CLI login

• IP Passthrough (not needed with IPv6)

• NAT (not needed with IPv6)

• Bounce pages

• UPnP

• Syslog

• SNMP over the WAN (LAN works)

There are two main types of IPv6 WAN connectivity: native (Auto and Static) and tunneling over IPv4 (6to4, 6in4, and

6rd).

• Native – (Auto and Static) The upstream ISP routes IPv6 packets directly.

• IPv6 tunneling – (6to4, 6in4, and 6rd) Each IPv6 packet is encapsulated by the router in an IPv4 packet and

routed over an IPv4 route to a tunnel endpoint that decapsulates it and routes the IPv6 packet natively. The reply is

encapsulated by the tunnel endpoint in an IPv4 packet and routed back over an IPv4 route. Some tunnel modes do

not require upstream ISPs to route or even be aware of IPv6 traffic at all. Some modes are utilized by upstream

ISPs to simplify the configuration and rollout of IPv6.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Enable IPv6 and select the desired IPv6 connection method for this WAN interface.

• Disabled (default) – IPv6 disabled on this interface.

• Auto – IPv6 will use automatic connection settings (if available).

• Static – Input a specific IPv6 address for your WAN connection. This is provided by the ISP if it is supported.

• 6to4 Tunnel (http://en.wikipedia.org/wiki/6to4) – Encapsulates the IPv6 data and transfers it to an automatic tunnel

provider (if your ISP supports it).

• 6in4 Tunnel (http://en.wikipedia.org/wiki/6in4) – Encapsulates the IPv6 data and sends it to the configured tunnel

provider.

• 6rd Tunnel (IPv6 rapid deployment: http://en.wikipedia.org/wiki/IPv6_rapid_deployment) – Encapsulates the IPv6

data and sends it to a relay server provided by your ISP.

When you configure IPv6, you have the option to designate DNS Servers and Delegated Networks. Because of the

dual-stack setup, these settings are optional: when configured for IPv6, the router will fall back to IPv4 settings when

necessary.

DNS Servers

Each WAN device is required to connect IPv4 before connecting IPv6. Because of this, DNS servers are optional, as most

IPv4 DNS servers will respond with AAAA records (128-bit IPv6 DNS records, most commonly used to map hostnames to

the IPv6 address of the host) if requested. If no IPv6 DNS servers are configured, the system will fall back to the DNS

servers provided by the IPv4 configuration.

Delegated Networks

A delegated network is an IPv6 network that is inherently provided by or closely tied to a WAN IP configuration. The IPv6

model is for each device to have end-to-end IP connectivity without relying on any translation mechanism. In order to

achieve this, each client device on the LAN network needs to have a publicly routable IPv6 address.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Auto

IPv6 auto-configuration mode uses DHCPv6 and/or SLAAC to configure the IPv6 networks. When you select Auto, all of

the following settings are optional (depending on your provider’s requirements):

• PD Request Size – Prefix Delegation request size. This is the size of IPv6 network that will be requested from the

ISP to delegate to LAN networks. (Default: 63)

• Primary IPv6 DNS Server – (optional) Depending on your provider, this may be required. This only takes effect if

the default global DNS setting on the Network Settings → DNS page is "Automatic".

• Additional IPv6 DNS Server – Secondary DNS server.

• Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this

may be required. Prefixes specified here only take effect if those supplied by the connection are insufficient to

configure your LANs.

• Delegated IPv6 Network – Additional network available for delegation to LANs.

Example Configuration:

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Static

As with IPv4, static configuration is available for situations where the WAN IPv6 topology is fixed.

• IPv6 Address/CIDR – Input the IPv6 static IP address and mask length provided by your ISP (see

http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing for an explanation of CIDR).

• IPv6 Gateway IP – Input the IPv6 remote gateway IP address provided by your ISP.

• Primary IPv6 DNS Server – (optional) Depending on your provider/setup, this may be required. This only takes

effect if the default global DNS setting on the Network Settings → DNS page is "Automatic".

• Additional IPv6 DNS Server – Secondary DNS server.

• Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this

may be required. Prefixes specified here only take effect if those supplied by the connection are insufficient to

configure your LANs.

• Delegated IPv6 Network – Additional network available for delegation to LANs.

Example Configuration:

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6to4 Tunnel

Out of the box, 6to4 is the simplest mode to enable full end-to-end IPv6 connectivity in an organization if the upstream ISP

properly routes packets to and from the 6to4 unicast relay servers.

• Primary IPv6 DNS Server – (optional) Depending on your provider, this may be required. This only takes effect if

the default global DNS setting on the Network Settings → DNS page is "Automatic".

• Additional IPv6 DNS Server – Secondary DNS server.

• Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this

may be required. Prefixes specified here only take effect if those supplied by the connection are insufficient to

configure your LANs.

• Delegated IPv6 Network – Additional network available for delegation to LANs.

Example Configuration:

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6in4 Tunnel

The 6in4 tunnel mode utilizes explicit IPv4 tunnel endpoints and encapsulates IPv6 packets using 41 as the specified

protocol type in the IP header. A 6in4 tunnel broker provides a static IPv4 server endpoint, decapsulates packets and

provides routing for both egress and ingress IPv6 packets. Most tunnel brokers provide a facility to request delegated

networks for use through the tunnel.

• Tunnel Server IP – Input the tunnel server IP address provided by your tunnel service.

• Local IPv6 Address – Input the local IPv6 address provided by your tunnel service.

• Primary IPv6 DNS Server – (optional) Depending on your provider, this may be required. This only takes effect if

the default global DNS setting on the Network Settings → DNS page is "Automatic".

• Additional IPv6 DNS Server – Secondary DNS server.

• Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this

may be required. Prefixes specified here only take effect if those supplied by the connection are insufficient to

configure your LANs.

• Delegated IPv6 Network – Additional network available for delegation to LANs.

Example Configuration:

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

6rd Tunnel

IPv6 Rapid Deployment (6rd) is a method of IPv6 site configuration derived from 6to4. It is different from 6to4 in that the

ISP provides explicit 6rd infrastructure that handles the IPv4 ↔ IPv6 translation within the ISP network. 6rd is considered

more reliable than 6to4 as the ISP explicitly maintains infrastructure to support tunneled IPv6 traffic over their IPv4

network.

• 6rd Prefix – The 6rd prefix and prefix length should be supplied by your ISP.

• IPv4 Border Router Address – This address should be supplied by your ISP.

• IPv4 Common Prefix Mask – Input the number of common prefix bits that you can mask off of the WAN's IPv4

address.

• Primary IPv6 DNS Server – (optional) Depending on your provider, this may be required. This only takes effect if

the default global DNS setting on the Network Settings → DNS page is "Automatic".

• Additional IPv6 DNS Server – Secondary DNS server.

• Delegated IPv6 Network – (optional) Network available for delegation to LANs. Depending on your provider, this

may be required. Prefixes specified here only take effect if those supplied by the connection are insufficient to

configure your LANs.

• Delegated IPv6 Network – Additional network available for delegation to LANs.

7.1.6 Modem Settings

Not all modems will have all of the options shown below; the available options are specific to the modem type.

On Demand: Typically modem connections are not

always on. When this mode is selected a connection to

the Internet is made as needed. When this mode is not

selected a connection to the Internet is always

maintained.

IP WAN Subnet Filter: This feature will filter out any

packets going to the modem that do not match the

network (address and netmask).

Aggressive Reset: When Aggressive Reset is enabled the system will attempt to maintain a good modem connection. If

the Internet has been unreachable for a period of time, a reset of the modem will occur in attempt to re-establish the

connection.

Enable Aux Antenna: Enable or disable the modem's auxiliary diversity antenna. This should normally be left enabled.

Modem Connection Mode: Specify how the modem should connect to the network. Not all options are available for all

modems; this will default to Auto if an incompatible mode is selected.

• Auto (all modes): Let the modem decide which network to use.

• Auto 3G (3G or less): Let the modem decide which 2G or 3G network to use. Do not attempt to connect to LTE.

• Force LTE: Connect to LTE only and do not attempt to connect to 3G or WiMAX.

Network Selection Mode: Wireless carriers are assigned unique network identifying codes known as PLMN (Public Land

Mobile Network). To manually select a particular carrier, select the Manual radio button and enter the network PLMN.

Functional Mode: Selects the functional mode of the modem. IPPT mode causes the modem to act as a transport,

passing Internet data and IP address information between the modem and the Internet directly. NAT mode causes the

modem to NAT the IP address information. Consequently, IPPT mode does not allow user access to the modem web UI

and NAT mode does allow user access to the modem web UI.

AT Config Script: Enter the AT commands to be used for carrier specific modem configuration settings. Each command

must be entered on a separate line. The command and associated response will be logged, so you should check the

system log to make sure there were no errors.

NOTE: AT Config Script should not be used unless told to do so by your modem's cellular provider or by a support technician.

AT Dial Script: This is included for legacy devices only. Most users will not use this option. Go to SIM/APN/Auth

Settings instead if you need to select a specific Access Point Name.

If you do need this option for older devices, enter the AT commands to be used in establishing a network connection.

7.1.10 Update/Activate a Modem

Some 3G/4G modems can be updated and activated while plugged into the router. Updates and activation methods vary

by modem model and service provider. Possible methods are: PRL Update, Activation, and FUMO. All supported methods

will be displayed when you select your modem and click “Control”. If no methods are displayed for your device then you

will need to update and activate your device externally.

To update or activate a modem, select the device and click

“Control”.

The modem does not support Update/Activate methods: A

message will state that there is no support for PRL Update,

Activation, or FUMO.

The modem supports Update/Activate methods: A message

will display showing options for each supported method:

• Modem Activation / Update: Activate, Reactivate, or

Upgrade Configuration.

• Preferred Roaming List (PRL) Update

• Firmware Update Management Object (FUMO)

Click the appropriate icon to start the process.

If the modem is connected when you start an operation the

router will automatically disconnect it. The router may start

another modem as a failover measure. When the operation is

done the modem will go back to an idle state, at which point the

router may restart it depending on failover and failback settings.

NOTE: Only one operation is supported at a time. If you try to start the same

operation on the same modem twice the UI will not report failure and the

request will finish normally when the original request is done. However if you

try to start a different operation or use a different modem, this second request

will fail without interfering with the pending operation.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Process Timeout: If the process fails an error message will display.

Activation has a 3-minute timeout, PRL update has a 4-minute timeout, and FUMO has

a 10-minute timeout.

Update Modem Firmware

Click on the Firmware button to open the Modem

Firmware Upgrade window. This will show whether

there is new modem firmware available.

If you select Automatic (Internet) the firmware will

be updated automatically. Use Manual Firmware

Upgrade to instead manually upload firmware from

a local computer or device.

7.1.11 Configuration Rules (Advanced)

This section allows you to create general rules that

apply to the Internet connections of a particular

type. These can be general or very specific. For

example, you could create a rule that applies to all

WiMAX modems, or a rule that only applies to an

Internet source with a particular MAC address.

The Configuration Rules list shows all rules that

you have created, as well as all of the default

rules. These are listed in the order they will be

applied. The most general rules are listed at the

top, and the most specific rules are at the bottom.

The router goes down the list and applies all rules

that fit for attached Internet sources. Configuration

settings farther down the list will override previous

settings.

Select any of these rules and click “Edit” to change the settings for a rule. To create a new rule, click “Add.”

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

WAN Configuration Rule Editor

After clicking “Add” or “Edit,” you will see a popup

with the following tabs:

• Filter Criteria

• General Settings

• IP Overrides

• IPv6 Settings

• Ethernet Settings

• Modem Settings

• WiMAX Settings

• CDMA Settings

• SIM/APN/Auth Settings

Filter Criteria. Begin by setting the Filter Criteria if you are creating a new rule. Create a name for your rule and the

condition for which the rule applies:

Rule Name: Create a name meaningful to you. This name is optional.

Select each of the following to create a condition for your rule. When:

• Port (USB Port 1, 2; ExpressPort): Select by the port that you are plugging the modem into.

• Manufacturer: Select by the manufacturer, such as Sierra Wireless.

• Model: Set your rule according to the specific model of modem.

• Type (LTE, Modem, WiMAX, HSPA): Select by type of Internet source.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

• Serial Number: Select 3G or LTE modem by Serial Number.

• MAC Address: Select WiMAX modem by MAC Address.

• Unique ID: Select by ID. This is generated by the router and displayed when the device is connected to the

router.

Condition: Select “is,” “is not,” “starts with,” “contains,” or “ends with” to create your condition’s statement.

Value: If the correct values are available, select from the dropdown list. You may need to manually input the value.

The condition will be of the following form:

“ (When) is/is not (value) ”

For example:

“Type is not WiMAX”

“Port is USB Port 1”

Once you have established the condition for your configuration rule, choose from the other tabs to set the desired

configuration. All of the tab options – General Settings, IP Overrides, IPv6 Settings, Ethernet Settings, Modem

Settings, WiMAX Settings, CDMA Settings, and SIM/APN/Auth Settings – have the same configuration options shown

above in the WAN Configuration section (the options for Configuration Rules are the same as they are for individual

devices).

7.2 Data Usage

Data Usage Management & Alerts allows you to create and manage rules that help control the data usage of a modem.

If you have a limited data plan or a price increase on your plan after a certain amount of usage, a Data Usage Rule can

help you track these amounts. You can set a rule to shut down use of a modem and/or send a message when you reach a

data usage amount you set.

Enable Data Usage: Enabled/Disabled. (Default:

Disabled.)

When you select Enabled, you will see the Data Usage

Agreement shown to the right. The purpose of this

agreement is to ensure that you understand that the data

numbers for the CBA750B may not perfectly match those

of your carrier: CradlePoint cannot be held responsible.

You must accept the agreement by clicking Yes in order to

begin creating data usage rules.

Warning: You should set your data limits lower than your

Data Allowance and regularly compare the numbers

provided by the router with the numbers from your carrier.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

7.2.1 Data Usage Rules

The Date Usage Rule display shows basic

information for each rule you have created

(including rules created with a template). The

following information is displayed:

• Rule Name

• Enabled: True/False

• Date for Rule Reset

• Cycle Type: Daily, Weekly, or Monthly

• Cap: Amount in MB.

• Current Usage: Shown as an amount

in MB, as a percentage of the cap, and

in a bar graph.

Click Add to configure a new Data Usage Rule.

Data Usage Rule – page 1

Rule Name: Give your rule a name for later recognition.

WAN Selection: Select from the dropdown list of currently

attached WAN devices.

Assigned Usage in MB: Enter a cap amount in megabytes.

1024 megabytes equals 1 gigabyte.

Rule Enabled: (Default: Enabled.) Click to disable.

Use with Load Balancing: When checked, the Load Balancing

feature is allowed to use the thresholds and metrics of this rule

when making balance decisions. This causes Load Balancing to

spread the data usage between interfaces according to the

assigned usage rather than bandwidth. This is a best effort to

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

keep all interfaces with these rules at a similar percentage utilization of data (e.g. 10%, 50%, 90%) as the cycle

progresses, rather than quickly using 100% of a fast 1GB capped interface while using only a fraction of a slow 10GB

capped interface, thus leaving the rest of the cycle with only the slow interface. The Data Usage algorithm on the Load

Balancing page must be selected or this checkbox has no effect.

Data Usage Rule – page 2

Cycle Type: How often the rule will reset. The data usage

amount will be reset at the end of each cycle. Select the

length of a cycle from a dropdown menu with the following

choices:

• Daily

• Weekly

• Monthly

Cycle Start Date: Select the

date you wish the rule to begin.

This date will be used to track

when the rule will reset.

Shutdown WAN on Cap: If

selected, the WAN device will shut down when the

assigned usage is reached. A cycle reset or a rule deletion

will re-enable the device.

Send Alert on Cap: An email alert will be generated and sent when the assigned usage is reached.

WARNING: The SMTP mail server must be configured in System Settings → Device Alerts.

Custom Alert: When checked you enable a second email to be configured for a percentage of the assigned usage.

Percent of Usage (1-1000): If selected, a custom alert will be sent when your data usage reaches this percentage of your

usage cap. For example, you could set this at 90 percent so that you know when your usage is nearing 100 percent of the

cap.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

7.2.2 Template Configuration

Templates allow you to control multiple

WAN devices with the same rule. Each WAN

device that matches a template will

automatically have its own rule created.

For example, you can set a template rule for all mobile data modems that causes your router to send an alert after 1000 MB of usage in a month.

When you attach a new 4G USB modem, your template will immediately create a new Data Usage Rule for the attached modem that sends the

alert as specified.

Click Add to configure a new Template rule.

Create a Template Name that you can recognize.

The template will apply to one of the following

WAN types:

• All WAN

• All Modems

Select one of these types.

The rest of the rule settings options match those in

the Data Usage Rules. See the section above for

additional information about how to configure your

template usage rules.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

7.3 WAN Affinity and Load Balancing

WAN affinity and load balancing both require multiple WAN devices, which is not typical usage

Load Balance

Select the Load Balance

Algorithm from the following

dropdown options:

• Round-Robin: Evenly

distribute each session

to the available WAN connections.

• Rate: Distribute load based on the current upload and download rates. A WAN device's upload and download

bandwidth values can be set in Internet → Connection Manager.

• Spillover: This was the default algorithm in older (version 3) firmware. Load is always given to devices with the

most available bandwidth. The estimated bandwidth rate is based on a combination of the upload and download

configuration values and the observed capabilities of the device.

• Data Usage: This mode works in concert with the Data Usage feature (Internet → Data Usage). The router will

make a best effort to keep data usage between interfaces at a similar percentage of the assigned data cap in the

Data Usage rule for each interface, rather than distributing sessions based solely on bandwidth. For proper function

you need to create data usage rules for each WAN device you will be load balancing. Make certain to select the

"Use with Load Balancing" checkbox in the Data Usage rule editor.

WAN Affinity

WAN Affinity rules allow you to manage traffic in your network so that particular bandwidth uses are associated with

particular WAN sources. This allows you to prioritize bandwidth.

EXAMPLE: You could specify that your guest LAN is only associated with your Ethernet connection with no failover. Then if your

Ethernet connection goes down and the embedded modem connects for failover for your primary LAN, your guest LAN will not take

bandwidth from your primary LAN, saving you money.

Click “Add” to open the WAN Affinity Policy Editor and create a new WAN Affinity rule.

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

Name: Give a name for your rule that is meaningful to you.

DSCP (DiffServ): Differentiated Services Code Point is the successor to TOS (Type of Service). Use this field to select

traffic based on the DSCP header in each IP packet. This field is sometimes set by latency sensitive equipment such as

VoIP phones. If you know specific DSCP values, you can input one here.

DSCP Negate: When checked this rule will match on any packet that does NOT match the DSCP field.

Protocol: Select from the dropdown list to specify the protocol for a particular data use. Otherwise, leave “Any” selected.

• Any

• ICMP

• TCP

• UDP

• GRE

• ESP

• SCTP

Source IP Address, Source Netmask,

Destination IP Address, and Destination

Netmask: Specify an IP address or range of IP

addresses by combining an IP address with a

netmask for either “source” or “destination” (or

both). Source vs. destination is defined by traffic

flow. Leave these blank to include all IP

addresses (such as if your rule is defined by a

particular port instead).

EXAMPLE: If you want to associate this rule with your

guest LAN, you could input the IP address and

netmask for the guest LAN here (leaving the last slot

“0” to allow for any user attached to the guest

network):

• Source IP Address: 192.168.10.0

CRADLEPOINT CBA750B | USER MANUAL Firmware version 5.0

• Source Netmask: 255.255.255.0

Failover: (Default: Selected.) When this is selected and traffic from the chosen WAN device for this rule is interrupted, the

router will fail over to another available WAN device. Deselect this option to restrict this traffic to only the selected WAN

interface.

WAN Binding Type: You have several options for specifying the type of WAN interface(s) you want associated with your

rule. Designate the interface(s) by Port, Manufacturer, Model, Type, Serial Number, MAC Address, or Unique ID. This

selection will create a dropdown list of options to complete a sentence with the following form: “When ____ is ____,” such

as, “When Type is LTE.” You also have the option to replace “is” with “isn’t,” “starts with,” “ends with,” or “contains.”

• Port: Select from the dropdown list of possible WAN ports on the router.

o USB 1

o USB 2

• Serial Number: Select from a dropdown list of attached devices.

• MAC Address: Select from a dropdown list of attached devices.

• Unique ID: Select from a dropdown list of attached devices.

Load Balance Algorithm: Select the Load Balance Algorithm for this WAN Affinity rule from the following dropdown

options:

• Round-Robin: Evenly distribute each session to the available WAN connections.

• Rate: Distribute load based on the current upload and download rates. A WAN device's upload and download

bandwidth values can be set in Internet → Connection Manager.
