10 Drop-in Mode
Drop-in Mode (or transparent bridging mode) eases the installation of Peplink Balance on a live network
between the firewall and router, such that changes to the settings of existing equipment are not required.
Drop-in Mode is NOT applicable to Balance 20 and 30.
The following diagram illustrates the Drop-in Mode setup:
Check the box to Enable the Drop-in Mode. After enabling this feature and selecting the WAN for Drop-in
mode, various settings including the WAN's connection method and IP address will be automatically
updated.
When Drop-in Mode is enabled, the LAN and the WAN for Drop-in Mode ports will be bridged. Traffic
going in between the LAN hosts and WAN router will be forwarded to each other. In this case, the hosts
on both sides will not notice any IP or MAC address change.
After successfully setting up Peplink Balance as part of the network via Drop-in Mode, a Peplink Balance
210 will accommodate one additional WAN connection; 310 or 380 will accommodate two, 580 will
accommodate four, 710 will accommodate six, and 1350 will accommodate twelve additional WAN
connections respectively.
IMPORTANT NOTE for customers using Drop-in Mode and
going to upgrade from firmware 4.8.2 or below to 5.0+
MAC address passthrough for Drop-in Mode is implemented in firmware 5.0. If Drop-in Mode is
enabled when user is upgrading from previous firmware version, the ARP tables on the hosts on LAN
and WAN segments have to be flushed once or the hosts have to be rebooted. Otherwise, hosts on
one side may not be able to reach hosts on the other side of Peplink Balance until the old ARP records
expire. Units without enabling Drop-in Mode are not affected.
NOTE
PPTP server will be disabled under Drop-in Mode.

DNS servers. A WAN connection will be treated as down only if there is also no
response received from the public DNS servers.
Connections will be considered up if DNS responses are received from any one of
the health check DNS servers, regardless of a positive or negative result.
By default, the first two DNS servers of the WAN connection are used as the
Health Check DNS Servers.
Health Check Method: SmartCheck
SmartCheck applies only to the Peplink Balance 20/30/380 or above Mobile Internet connection. It
monitors the link status, and is optimized for mobile networks with high traffic latency.
Other Health Check Settings
Timeout
This setting specifies the timeout, in seconds, for ping/DNS lookup requests. Default
Timeout is set to 5 seconds.
Health Check
Interval
This setting specifies the time interval, in seconds, between ping or DNS lookup requests.
Default Health Check Interval is 5 seconds.
Health Check
Retries
This setting specifies the number of consecutive ping/DNS lookup timeouts after which
Peplink Balance is to treat the corresponding WAN connection as down. Default Health
Retries is set to 3.
For example, with the default Health Retries setting of 3, after consecutive 3 timeouts, the
corresponding WAN connection will be treated as down.

Recovery Retries
This setting specifies the number of consecutive successful ping/DNS lookup responses
that must be received before Peplink Balance treats a previously down WAN connection to
be up again.
By default, Recover Times is set to 3. For example, a WAN connection that is treated as
down will be considered to be up again upon receiving 3 consecutive successful ping/DNS
lookup responses.
Note
In case a WAN connection goes down, all of the WAN connections with non-Always-on Connection Type will also
be brought up until any one of higher priority WAN connections is up and found to be healthy. This design could
increase the overall network availability.
For example, if WAN1, WAN2 and WAN3 have the connection types of Always-on, Backup Priority Group 1 and
Backup Priority Group 2 respectively, when WAN1 goes down, WAN2 and WAN3 will also try to connect. If WAN3
is connected first, WAN2 will still be kept connecting. If WAN2 is connected, WAN3 will disconnect or abort making
connection.
Automatic Public DNS Server Check on DNS Test Failure
In case the health check method is set to DNS Lookup and checks failed, the Balance will automatically perform
DNS lookups on some public DNS servers. If the tests are success, it means the WAN may not be down but rather
the target DNS server became malfunctioned. You will see the following warning message on the Main page.

11.6 Dynamic DNS Settings
Peplink Balance provides the functionality to register the domain name relationships to dynamic DNS
service providers. Through registration with dynamic DNS service provider(s), the default public Internet
IP address of each WAN connection can be associated with a host name. With Dynamic DNS service
enabled for a WAN connection, you can connect to your WAN's IP address from the external even if its IP
address is dynamic. You have to register for an account from the listed dynamic DNS service providers
before enabling this option.
If the WAN connection's IP address is a reserved private IP address (i.e. behind a NAT router), the Public
IP of each WAN will be automatically reported to the DNS service provider.
Either upon a change in IP address or every 23 days without link reconnection, Peplink Balance will
connect to the dynamic DNS service provider to perform an IP address update within the provider’s
records.
The settings for dynamic DNS service provider(s) and the association of host name(s) are configured via
Network > Interfaces > WAN:
Dynamic DNS Settings
This setting specifies the dynamic DNS service provider to be used for the WAN based
on supported dynamic DNS service providers:
Service Provider
•
changeip.com
•
dyndns.org
•
no-ip.org
•
tzo.com
Select Disabled to disable this feature.
User ID / User / Email
This setting specifies the registered user name for the dynamic DNS service.
Password / Pass / TZO
This setting specifies the password for the dynamic DNS service.
Key
Hosts / Domain
This setting specifies a list of host names or domains to be associated with the public
Internet IP address of the WAN connection.
Important Note
In order to use dynamic DNS services, appropriate host name registration(s), as well as a valid account with a
supported dynamic DNS service provider are required.
A dynamic DNS update is performed whenever a WAN’s IP address changed. E.g. IP is changed after a DHCP IP
refresh, reconnection, etc.
Due to dynamic DNS service providers’ policy, a dynamic DNS host would expire automatically because the host
record was not updated for a long time. Therefore Peplink Balance performs an update every 23 days even if a
WAN’s IP address did not change.

12 Site-to-Site VPN
(Available on Peplink Balance 210+)
Peplink Balance Site-to-Site VPN functionality securely connects one or more branch offices to your
company's main headquarters or to other branches. The data, voice, or video communications between
these locations are kept confidential across the public Internet.
The Site-to-Site VPN of the Peplink Balance is specifically designed for multi-WAN environment. The
Peplink Balance can aggregate all WAN connections’ bandwidth for routing Site-to-Site VPN traffic.
Unless all the WAN connections of one site are down, the Peplink Balance can still maintain VPN up and
running.
VPN Bandwidth Bonding is supported in firmware 5.0+. All available bandwidth will be utilized to establish
the VPN tunnel, and all traffic will be load balanced at packet level across all links. VPN Bandwidth
Bonding is enabled by default.
Tip
You can define firewall rules to control access within the VPN network. Outbound traffic can be redirected and go
through VPN tunnels with custom outbound policies, please refer to section 13 for details
12.1 Site-to-Site VPN Settings
Peplink Balance 380, 580, 710 and 1350 support making multiple Site-to-Site VPN connections with a
remote Peplink Balance 210, 310, 380, 580, 710, 1350, or a Pepwave MAX Mobile Router. Peplink
Balance 210 and 310 support making two Site-to-Site VPN connections with a remote Peplink Balance
210, 310, 380, 580, 710, 1350, or a Pepwave MAX Mobile Router.
Peplink Balance that supports multiple VPN connections can act as a central hub which connects branch
offices. For example, branch office A and branch office B make VPN connections to headquarters C,
both branch offices’ LAN subnet and subnets behind it (i.e. static routes) will also be advertised to the
headquarters C and the other branches. So branch office A will be able to access branch office B via
headquarters C in this case.
The local LAN subnet and subnets behind the LAN (defined under Static Route in the LAN settings page)
will be advertised to the VPN. All VPN members (branch offices and headquarters) will be able to route
to the local subnets.
Note that all LAN subnet and subnets behind it have to be unique. Otherwise, VPN members will not be
able to access each other.
All data can be routed over the VPN with 256-bit AES encryption standard.

Link Failure Detection
Link Failure
Detection Time
The bonded Site-to-Site VPN can detect routing failures on the path between two
sites over each WAN connection. Failed WAN connections will not be used to
route VPN traffic. Health check packets are sent to the peer to detect any failure.
The more frequent checks it sends, the shorter detection time, but the higher
bandwidth overhead will be consumed.
When Recommended is selected, a health check packet is sent out every 5
seconds, and the expected detection time is 15 seconds.
When Fast is selected, a health check packet is sent out every 3 seconds, and the
expected detection time is 6 seconds.
When Faster is selected, a health check packet is sent out every 1 second, and
the expected detection time is 2 seconds.
When Extreme is selected, a health check packet is sent out every 0.1 second,
and the expected detection time is under 1 second.
By default, Recommended is selected.
Important Note to Users Upgrading to Firmware 5.0+
The Site-to-Site VPN in firmware 5.0+ requires the same firmware version for all devices in the VPN network.
Please make sure that both ends of the Peplink Balance units are running with the same firmware version.
Important Note
•
•
When outbound Internet traffic is routed to remote Site-to-Site VPN peer, the remote peer will route the
traffic to its first available WAN connection only.
Peplink proprietary Site-to-Site VPN used TCP and UDP port 32015 for establishing VPN connections. If
you have a firewall in front of the Peplink Balance devices, you will need to add firewall rules for these port
and protocols which will allow inbound and outbound traffic pass-through the firewall.

12.2 Peplink Balance Behind NAT Router
The Peplink Balance supports establishing Site-to-Site VPN over WAN connections which are behind a
NAT (Network Address Translation) router.
To be able for a WAN connection behind a NAT router to accept VPN connections, you can configure the
NAT router in front of the WAN connection to inbound port forward TCP port 32015 to the Peplink
Balance.
If one or more WAN connections on Unit A can accept VPN connections (by means of port forwarding or
not) while none of the WAN connections on the peer Unit B can do so, you should put all public IP
addresses or host names of the Unit A to the Unit B’s Peer IP Addresses / Host Names field. Leave
the field in Unit A blank. With such setting, site-to-site VPN connection can be set up and all WAN
connections on both sides will be utilized.
For example, see the following diagram:
One of the WANs of Balance A is non-NAT’d (212.1.1.1). The rest of the WANs on Balance A and all
WANs on Balance B are NAT’d. In such case, the Peer IP Addresses / Host Names field in Balance B
should be filled with all of the Balance A’s host names or public IP addresses (i.e. 212.1.1.1, 212.2.2.2
and 212.3.3.3), and the field in Balance A can be left blank. The two NAT routers on WAN1 and WAN3 of
Balance A should inbound port forward TCP port 32015 to the Balance A so that all WANs would be
utilized to establish VPN.

13.2.1 Algorithm: Weighted Balance
This setting specifies the ratio of WAN connection usage to be applied on the specified IP Protocol & Port,
and is applicable only when Algorithm is set to Weighted Balance.
The amount of matching traffic that is distributed to a WAN connection is proportional to the weight of
WAN connection relative to the total weight. Use the sliders to change each WAN’s weight.
Example: With the following weight settings on a Peplink Balance 310:
• WAN1: 10
• WAN2: 10
• WAN3: 5
Total weight is 25 = (10 + 10 + 5)
Matching traffic distributed to WAN1 is 40% = (10 / 25) x 100%
Matching traffic distributed to WAN2 is 40% = (10 / 25) x 100%
Matching traffic distributed to WAN3 is 20% = (5 / 25) x 100%
13.2.2 Algorithm: Persistence
The configuration of Persistent Services is the solution to the few situations where link load distribution for
Internet services is undesirable.
For example, many e-banking and other secure websites, for security reasons, terminate the session
when the client computer’s Internet IP address changes mid-session.
In general, different Internet IP addresses represent different computers. The security concern is that an
IP address change during a session may be the result of an unauthorized intrusion attempt. Therefore, to
prevent damages from the potential intrusion, the session is terminated upon the detection of an IP
address change.
Peplink Balance can be configured to distribute data traffic across multiple WAN connections. Also, the
Internet IP depends on the WAN connections over which communication actually takes place. As a result,
a LAN client computer behind Peplink Balance may communicate using multiple Internet IP addresses.
For example, a LAN client computer behind a Peplink Balance 310 with three WAN connections may
communicate on the Internet using three different IP addresses.
With the Persistency feature of Peplink Balance, rules can be configured to enable client computers to
persistently utilize the same WAN connections for e-banking and other secure websites. As a result, a
client computer will communicate using one IP address and eliminate the issues.

There are two Persistent Modes. One is by source and the other by destination.
By Source:
The same WAN connection will be used for traffic matching the rule and
originating from the same machine regardless of its destination. This option will
provide the highest level of application compatibility.
By Destination:
The same WAN connection will be used for traffic matching the rule, originating
from the same machine, and going to the same destination. This option can better
distribute load to WAN connections when there are only a few client machines.
The default Mode is By Source.
When there are multiple client requests, they can be distributed (persistently) to WAN connections with a
weight. If you choose Auto in Load Distribution, the weights will be automatically adjusted according to
each WAN’s Download Bandwidth which is specified in the WAN settings page (see Section 11
Configuration of WAN Interface(s)). If you choose Custom, you can customize the weight of each WAN
manually by using the sliders.
13.2.3 Algorithm: Enforced
This setting specifies the WAN connection usage to be applied on the specified IP Protocol & Port, and is
applicable only when the Algorithm is set to Enforced.
Matching traffic will be routed through the specified WAN connection regardless of health check status of
the WAN connection.
Starting from firmware 5.2, outbound traffic can be enforced to go through a specified Site-to-Site VPN
connection. (Available on Peplink Balance 210+)
13.2.4 Algorithm: Priority
This setting specifies the priority of the WAN connections to be utilized to route the specified network
service. The highest priority WAN connection available will always be used for routing the specified type
of traffic. A lower priority WAN connection will be used only when all higher priority connections have
become unavailable.
Starting from firmware 5.2, outbound traffic can be prioritized to go through Site-to-Site VPN
connection(s). By default, VPN connections are not included in the priority list. (Available on Peplink
Balance 210+)

13.2.5 Algorithm: Overflow
The traffic matching this rule will be routed through the healthy WAN connection that has the highest
priority and is not in full load. When this connection gets saturated, new sessions will be routed to the
next healthy WAN connection that is not in full load.
Drag and drop to specify the order of WAN connections to be used for routing traffic. Only the highest
priority healthy connection that is not in full load will be utilized.
13.2.6 Algorithm: Least Used
(Available on Peplink Balance 210+)
The traffic matching this rule will be routed through the healthy WAN connection that is selected in the
field Connection and has the most available download bandwidth. The available download bandwidth of
a WAN connection is calculated from the total download bandwidth specified in the WAN settings page
and the current download usage. The available bandwidth and WAN selection is determined every time
when an IP session is made.
13.2.7 Algorithm: Lowest Latency
(Available on Peplink Balance 210+)
The traffic matching this rule will be routed through the healthy WAN connection that is selected in the
field Connection and has the lowest latency. Latency checking packets are issued periodically to a
nearby router of each WAN connection to determine its latency value. The latency of a WAN is the
packet round trip time of the WAN connection. Additional network usage may be incurred as a result.
Tip
The round trip time of a “6M down / 640k up” link can be higher than that of a “2M down / 2M up” link. It is because
the overall round trip time is lengthened by its slower upload bandwidth despite of its higher downlink speed.
Therefore this algorithm is good for two scenarios:
•
All WAN connections are symmetric; or
•
A latency sensitive application requires to be routed through the lowest latency WAN regardless the WAN’s
available bandwidth.

The IP Protocol setting, along with the Port setting, specifies the protocol of the service as TCP,
UDP, ICMP or IP.
Traffic that is received by Peplink Balance via the specified protocol at the specified port(s) is
forwarded to the LAN hosts specified by the Servers setting.
IP Protocol
(Please refer below for details on the Port and Servers settings.)
Alternatively, the Protocol Selection Tool drop-down menu can be used to automatically fill in
the Protocol and a single Port number of common Internet services (e.g. HTTP, HTTPS, etc.)
After selecting an item from the Protocol Selection Tool drop-down menu, the Protocol and
Port number remains manually modifiable.
The Port setting specifies the port(s) that correspond to the service, and can be configured to
behave in one of the following manners:
Any Port, Single Port, Port Range, Port Map and Range Mapping
Any Port: all traffic that is received by Peplink Balance via the specified protocol is forwarded to
the servers specified by the Servers setting.
For example, with IP Protocol set to TCP, and Port set to Any Port, all TCP traffic is forwarded
to the configured servers.
Single Port: traffic that is received by Peplink Balance via the specified protocol at the specified
port is forwarded via the same port to the servers specified by the Servers setting.
For example, with IP Protocol set to TCP, and Port set to Single Port and Service Port 80,
TCP traffic received on Port 80 is forwarded to the configured servers via Port 80.
Port
Port Range: traffic that is received by Peplink Balance via the specified protocol at the
specified port range is forwarded via the same respective ports to the LAN hosts specified by
the Servers setting.
For example, with IP Protocol set to TCP, and Port set to Port Range and Service Port 80-88,
TCP traffic received on ports 80 through 88 is forwarded to the configured servers via the
respective ports.
Port Mapping: traffic that is received by Peplink Balance via the specified protocol at the
specified port is forwarded via a different port to the servers specified by the Servers setting.

The Port setting specifies the port(s) that correspond to the service, and can be configured to
behave in one of the following manners:
Any Port, Single Port, Port Range, Port Map and Range Mapping
Any Port: all traffic that is received by Peplink Balance via the specified protocol is forwarded
to the servers specified by the Servers setting.
For example, with IP Protocol set to TCP, and Port set to Any Port, all TCP traffic is
forwarded to the configured servers.
Single Port: traffic that is received by Peplink Balance via the specified protocol at the
specified port is forwarded via the same port to the servers specified by the Servers setting.
For example, with IP Protocol set to TCP, and Port set to Single Port and Service Port 80,
TCP traffic received on Port 80 is forwarded to the configured servers via Port 80.
Port
Port Range: traffic that is received by Peplink Balance via the specified protocol at the

UPnP and NAT-PMP are network protocols which allow a computer on the LAN to automatically configure
the router to allow parties on the WAN to connect to itself. In this way, the process of inbound port
forwarding is automated.
When a computer creates a rule using these protocols, the specified TCP/UDP port of all WAN
connections' default IP address will be forwarded.
Check the corresponding box(es) to enable UPnP and/or NAT-PMP. Enable these features only if you

14.5 Definition of DNS Records
(Available on Peplink Balance 210+)
The built-in DNS Server functionality of Peplink Balance facilitates inbound load balancing. With the
presence of the functionality, NS/SOA DNS records for a domain name can be delegated to Internet IP
address(es) of Peplink Balance. Upon receiving a DNS query, Peplink Balance supports returning, as an
“A” record, the corresponding IP address for the domain name on the most appropriate healthy WAN
connection. It also supports acting as a generic DNS server for hosting “A”, “CNAME”, “MX”, “TXT” and
“NS” records.
For example:
(This example is for illustration only; the actual resolution that takes place in implementation will likely be
different.)
The DNS resolution of the domain name www.mycompany.com is delegated to the WAN2 Internet IP
addresses of Peplink Balance.
Upon receiving the DNS query, Peplink Balance returns, as an “A” record, the IP address for
www.mycompany.com on WAN1 because WAN1 is the most appropriate healthy link.
The settings for defining the DNS records to be hosted by Peplink Balance are located at: Network >
Inbound Access > DNS Settings

record 44.33.22.11.in-addr.arpa pointing to www.mydomain.com will also be created.
When there are multiple host names pointing to the same IP address, only one PTR record for the IP
address will be created.
In order to have the PTR records working, you will also have to create NS records for the PTR records.
For example, if the IP address range 11.22.33.0 to 11.22.33.255 is delegated to the DNS server on the
Peplink Balance, you will also have to create a domain 33.22.11.in-addr.arpa and have its NS records
pointing to your DNS server’s (the Peplink Balance) public IP addresses.
With the above records created, the PTR record creation is complete.

14.6 Reverse Lookup Zones
Reverse lookup refers to performing a DNS query to find one or more DNS names associated with a
given IP address.
The DNS stores IP addresses in the form of specially formatted names as pointer (PTR) records using
special domains/zones. The zone is in-addr.arpa.
To enable DNS clients to perform a reverse lookup for a host, perform two steps:
Create a Reverse Lookup Zone that corresponds to the subnet network address of the host.
In the Reverse Lookup Zone, add a pointer (PTR) resource record that maps the host IP address to the
host name.
Click the New Reverse Lookup Zone button and enter a Reverse Lookup Zone Name. If you are
delegated the subnet 11.22.33.0/24, the Zone Name should be 33.22.11.in-arpa.addr. PTR records for
11.22.33.1, 11.22.33.2, ... 11.22.33.254 should be defined in this zone where the Host IP Numbers are 1,

19 Miscellaneous Settings
The miscellaneous settings include configuration for High Availability, PPTP Server, Service Forwarding,
and Service Passthrough.
19.1 High Availability
(Available on Peplink Balance 210+)
Peplink Balance supports High Availability (HA) configurations via an open standard Virtual Router
Redundancy Protocol (VRRP, RFC 3768).
In an HA configuration, two same-model Peplink Balance units (e.g. a pair of Peplink Balance 210 units,
or a pair of Peplink Balance 710 units) provide redundancy and failover in a master-slave arrangement.
From a high level, in the event that the Master Unit is down, the Slave Unit becomes active.
High Availability will be disabled automatically where there is a Drop-in connection configured on a LAN
Bypass port.
The following diagram illustrates an HA configuration with two Peplink Balance 210 units, and two Internet
connections:
In the diagram, the WAN ports on each Peplink Balance unit connect to the router and modem; and
Peplink Balance unit connects to the same LAN switch via a LAN port.
An elaboration on the technical details of the implementation, by Peplink Balance, of Virtual Router
Redundancy Protocol (VRRP, RFC 3768) follows:

In an HA configuration, the two Peplink Balance units communicate with each other using VRRP
over the LAN.

The two Peplink Balance units broadcast heartbeat signals to the LAN at a frequency of one
heartbeat signal per second.

In the event that no heartbeat signal from the Master Peplink Balance unit is received in 3
seconds (or longer) since the last heartbeat signal, the Slave Peplink Balance unit becomes
active.

The Slave Peplink Balance unit initiates the WAN connections, and binds to a previously
configured LAN IP address.

At a subsequent point when the Master Peplink Balance unit recovers, it will once again become
active.
The settings to configure High Availability are located at the following location: Network > Misc. Settings
> High Availability:

Subnet Mask
The setting specifies the LAN IP address on which the active Peplink Balance
listens.
The value of Virtual IP represents a LAN IP address that is shared among the
Master and Slave units; however, at any time, only one of the two units will listen on
the IP address.
If the WAN is configured in NAT mode, Default Gateway of the clients on the LAN
should be set to the virtual IP. These configurations are not required when the WAN
is configured in Drop-in mode.
This setting specifies a LAN IP address to be used for accessing administration
functionality.
This address should be unique within the LAN.
This setting specifies the subnet mask of the LAN.

SMTP Forwarding
When this option is enabled, all outgoing SMTP connections destined for any
host at TCP port 25 will be intercepted. These connections will be redirected
to a specified SMTP server and port number. SMTP server settings for each
WAN can be specified after selecting Enable.
Web Proxy Forwarding
When this option is enabled, all outgoing connections destined for the proxy
server specified in Web Proxy Interception Settings will be intercepted. These
connections will be redirected to a specified web proxy server and port
number. Web Proxy Interception Settings and proxy server settings for each
WAN can be specified after selecting Enable.
DNS Forwarding
When this option is enabled, all outgoing DNS lookups will be intercepted and
redirected to the built-in DNS name server.
If any LAN device is using DNS name servers of a WAN connection, you may
want to enable this option to enhance the DNS availability without modifying
the DNS server setting of the clients. The built-in DNS name server will
distribute DNS lookups to corresponding DNS servers of all available WAN
connections. In this case, DNS service will not be interrupted even if any
WAN connection is down.
19.3.1 SMTP Forwarding
Some ISPs require their users to send e-mails via the ISP’s SMTP server. All outgoing SMTP
connections are blocked except those connecting to the ISP’s. The Peplink Balance supports to intercept
and redirect all outgoing SMTP connections (destined for TCP port 25) via a WAN connection to the
WAN’s corresponding SMTP server.

19.4 Service Passthrough
Service Passthrough settings can be found at: Network > Misc. Settings > Service Passthrough
Some Internet services required to be specially handled in a multi-WAN environment. The Peplink
Balance supports handling such services correctly such that Internet applications do not notice it is
behind a multi-WAN router. Settings for Service Passthrough Support are available here.
Service Passthrough Support
SIP
Session Initiation Protocol, aka SIP, is a voice-over-IP protocol. Peplink Balance can act
as a SIP Application Layer Gateway (ALG) which binds connections for the same SIP
session to the same WAN connection and translate IP address in the SIP packets
correctly in NAT mode. Such passthrough support is always enabled and there are two
modes for selection: Standard Mode and Compatibility Mode
If your SIP server’s signal port number is non-standard, you can check the box Define
custom signal ports and input the port numbers to the text boxes.
H.323
FTP
With this option enabled, protocols that provide audio-visual communication sessions will
be defined on any packet network and passthrough the Balance.
FTP sessions consist of two TCP connections; one for control and one for data. In multiWAN situation, they have to be binded to the same WAN connection. Otherwise,
problems will arise in transferring files. By default, the Peplink Balance monitors TCP
control connections on port 21 for any FTP connections and binds TCP connections of
the same FTP session to the same WAN.
If you have an FTP server listening on a port number other than 21, you can check the
box Define custom control ports and enter the port numbers to the text boxes.
TFTP
The Peplink Balance monitors outgoing TFTP connections and routes any incoming
TFTP data packets back to the client. Select Enable if you want to enable the TFTP
Passthrough support.
This field is for enabling the support of IPsec NAT-T Passthrough. UDP ports 500, 4500
and 10000 are monitored by default.
IPsec NAT-T
You may add more custom data ports that your IPsec system uses by checking the
box Define custom ports. If the VPN contains IPsec Site-to-Site VPN traffic, you have
to check the box Route IPsec Site-to-Site VPN and choose the WAN connection to route
the traffic to.
If you have IPsec Site-to-Site VPN traffic routed, check the Route IPsec Site-to-Site
VPN option and select a WAN to force routing such traffic to the specified WAN.

Appendix B. Routing under DHCP, Static IP, and PPPoE
The information in this appendix applies only to situations where Peplink Balance operates with to a WAN
connection under DHCP, Static IP, and PPPoE.
For information that applies to GRE, please refer to:

Section 11.1.4.1, Routing under GRE via Network Address Translation (NAT)

Section 11.1.4.2, Routing under GRE via IP Forwarding
B.1
Routing via Network Address Translation (NAT)
When Peplink Balance is operating under NAT mode, the source IP addresses of outgoing IP packets are
translated to the WAN IP address of Peplink Balance. Therefore, with NAT, all LAN devices share the
same WAN IP address to access the Internet (i.e. the WAN IP address of Peplink Balance).
Operating Peplink Balance in NAT mode requires only one WAN (Internet) IP address. In addition,
operating in NAT mode also has security advantages because LAN devices are hidden behind Peplink
Balance, not directly accessible from the Internet, and, hence, less vulnerable to attacks.
The following figure shows the packet flow in NAT mode:

Appendix C. Case Studies
C.1
Performance Optimization
C.1.1 Scenario
In this scenario, email and web browsing are the two main Internet services used by the LAN users.
The mail server is external to the network.
The connections are ADSL (with slow uplink and fast downlink) and Metro Ethernet (symmetric).
C.1.2 Solution
The solution is to individually set the WAN loading balance according to the service.

Web browsing mainly downloads data; sending e-mails mainly consumes upload bandwidth.

Both connections offer good download speeds; WAN2 offers good upload speeds.

Define WAN1 and WAN2's inbound and outbound bandwidths to be 3M/512k and 4M/4M
respectively.

For HTTP, set the weight to 3 : 4.

For SMTP, set the weight to 1 : 8, such that users will have a greater chance to be routed via
WAN2 when sending e-mail.
C.1.3 Settings

C.2
Maintaining the Same IP Address throughout a Session
C.2.1 Scenario
Some client IP address sensitive web sites (for example, Internet banking) use both client IP address and
cookies matching for session identification. Since different IP addresses are used during the load
balancing, the session is dropped when a mismatching IP is detected.
C.2.2 Solution
Make use of the Persistency functionality of Peplink Balance.
With Persistence is configured and the option By Destination is selected, Peplink Balance uses a
consistent WAN connection for source-destination pairs of IP addresses, and prevents sessions from
being dropped.
With Persistence is configured and the option By Source is selected, Peplink Balance uses a consistent
WAN connection for same source IP addresses. This option offers even higher application compatibility
but the outbound traffic load will be distributed more evenly only if more users use the Internet.
C.2.3 Settings
Set persistence in:
Network > Outbound Policy > Managed by Custom Rules
Click Add Rule, select HTTP (TCP port 80) for web service, and select Persistence.
Tip
A network administrator can use the Traceroute utility to manually analyze the connection path of a
particular WAN connection.

Bypassing the Firewall to Access Hosts on LAN
C.3.1 Scenario
There are times when remote access to computers on the LAN is desirable; for example, when hosting
web sites, online businesses and FTP download and upload areas, etc.
In such cases, it may be appropriate to create an inbound NAT mapping for the network to allow some
hosts on the LAN to be accessible from outside of the firewall.
C.3.2 Solution
Web Admin Interface can be used for adding an inbound NAT mapping to a host and to bind the host to
the WAN connections, via Network > NAT Mappings > Add NAT Rule
For example, the following settings add the host, with IP address 192.168.1.102, to an Inbound Mapping
and bind the host to the default IP and 211.123.123.100 of WAN1:

Inbound Access Restriction
C.4.1 Scenario
A firewall is required in order to protect the network from potential hacker attacks and other Internet
security threats.
C.4.2 Solution
Firewall functionality is built into Peplink Balance. By default, inbound access is unrestricted.
Enabling a basic level of protection involves setting up firewall rules.
For example, to set up a firewall rule between the Internet and the private network that monitors Web
access from Internet, click the Add Rule button in the Inbound Firewall Rules table, and then change
the settings according to the following screenshot:
After the fields have been entered as in the screenshot, click Save to add the rule.

For security reasons, it may be appropriate to disallow LAN users to use ftp to transfer files to and from
the Internet, or otherwise restrict outbound access.
This can easily be achieved by setting up an outbound firewall rule with Peplink Balance.
C.5.2 Solution
To set up a firewall between Internet and private network for outbound access, click the Add Rule button
in the Outbound Firewall Rules table, and then make the settings according the following screenshot:

Appendix D. Troubleshooting
Problem 1
Outbound load is only distributed over one WAN connection.
Solution
Outbound load can only be distributed evenly to the WAN connection if many outbound connections are
made. If there is only one user on the LAN and only one download session is made from his/her browser,
the WAN connections cannot be fully utilized.
For a single user, download manager applications are recommended. The applications can split a file
into pieces and download the pieces simultaneously. For example: FlashGet (Windows), GetRight
(Windows), iGetter (MAC), etc.
If the outbound traffic is going across the Site-to-Site VPN tunnel, i.e. transferring a file to a VPN peer, all
WAN connections will be bonded by our Site-to-Site VPN technology. In this case, all bandwidth will be
utilized and a file will be transferred across all available WAN connections.
For details, please refer to this FAQ: http://www.peplink.com/index.php?view=faq&id=111&path=19
Problem 2
I am using a download manager program (e.g. FlashGet, Download Accelerator Plus, DownThemAll etc.)
now. Why is the download speed still in single link's speed?
Solution
First, check whether the WAN connections are up.
Second, ensure your download manager application has split the file into 3 parts or more.
It is also possible that all of 2 or even 3 download sessions were being distributed to the same link by
chance.
Problem 3
I am using some websites to lookup my public IP address, e.g. www.whatismyip.com. When I keep
pressing the browser's Refresh button, the server almost always returns the same address. The IP
address supposed to be changing for every refresh
Solution
The web server has enabled the Keep Alive function such that you were using the same TCP session to
query the server.
Try to test with a web site that does not enable Keep Alive.
For example, try http://private.dnsstuff.com/tools/aboutyou.ch (This third-party web site is provided only
for reference. Peplink has no association with the site and does not guarantee the site's validity or
availability.)
Problem 4
What can I do if I suspect a problem on my LAN connection?
Solution
You can test the LAN connection using Ping.
For example, if you are using DOS/Windows, at the Command Prompt, type:
ping 192.168.1.1
This pings the Peplink Balance device (provided that Peplink Balance device’s IP is 192.168.1.1) to test
whether the connection to Peplink Balance is OK.

USER MANUAL
Peplink Balance Series
Problem 5
What can I do if I suspect a problem on my Internet/WAN connection?
Solution
You can test the WAN connection by Ping, which is similar to problem 4.
As we want to isolate the problems from the LAN, Ping will be performed from Peplink Balance. By using
the Ping/Traceroute under the tab Status of the Peplink Balance, you may able to find out the source of
problem.
Problem 6
When I upload files to a server via ftp, the transfer stalls after a few kilobytes of data are sent. What
should I do?
Solution
The Maximum Transmission Unit (MTU) or MSS setting may need to be adjusted.
By default, the MTU is set at 1440. Choose Auto for all of your WAN connections. If it does not solve, you
may try the MTU 1492 if a connection is a DSL. If problem still persists, change the size to smaller values
until your problem is resolved (e.g. 1462, 1440, 1420, 1400, etc).
