14 Outbound Policy Management

The Peplink Balance canflexibly manage and load balance outbound traffic among WAN connections.

Important Note

Outbound policy is applied only when more than one WAN connection is active.

The settings for managing and load balancing outbound traffic are located at

Network> Outbound Policy.

Peplink Balance Series

14.1 Outbound Policy

There are three main selections for the outbound traffic policy:

 High Application Compatibility

 Normal Application Compatibility

 Custom

Outbound Policy Settings

High Application

Compatibility

Outbound traffic from a source LAN device is routed through the same WAN connection

regardless of the destination Internet IP address and protocol.

This option provides the

highest application compatibility.

Normal

Application

Compatibility

Outbound traffic from a source LAN device to the same destination Internet IP address will

be routed through the same WAN connection persistently,regardless of protocol. This

option provides high compatibility to most applications, and users still benefit from WAN link

load balancing when multiple Internet servers are accessed.

Custom

Outbound traffic behavior can be managed by defining rules in a custom rule table. A

default rule can be defined for connections that cannot be matched with any of the rules.

The default policy is Normal Application Compatibility.

14.2 Custom Rules for Outbound Policy

Click in the Outbound Policy form.Choose Custom and press the Savebutton.The followingscreen

will then be displayed:

The bottom-most rule is Default. Edit this rule to change the device’s default manner ofcontrolling

outbound traffic for all connections that donot match any of the rules above it. Under the Service he––

ading,Defaultto change thesesettings. To rearrange the priority of outbound rules, drag and drop them

into the desired sequence.

By default, Auto is selected for as theDefault Rule.You can select Custom to change the algorithm to be

used. Please refer to the upcoming sections for the details onthe available algorithms.

To create a custom rule, click Add Rule at the bottom of the table.The following window will be displayed:

USER MANUAL

Peplink Balance Series

New Custom Rule Settings

Service Name

This setting specifies the name of the outbound traffic rule.

Enable

This setting specifies whether the outbound traffic rule takes effect.When Enable is

checked, the rule takes effect: traffic is matched and actions are takenby the Peplink

Balance based on the other parameters of the rule.When Enable is unchecked, the rule

does not take effect: the PeplinkBalance disregards the other parameters of the rule.

Source

This setting specifies the

source IP address, IP network, or MAC address for traffic

that

matches the rule.

Destination

This setting specifies the destination IP address, IP network, or domain name for traffic that

matches the rule.

If Domain Name is chosen and a domain name, such as foobar.com, is entered, any

outgoing accesses to foobar.com and *.foobar.com will match this criterion. You may enter

a wildcard (.*) at the end of a domain name to match any host with a name having the

domain name in the middle. If you enter foobar.*, for example, www.foobar.com,

www.foobar.co.jp, or foobar.co.uk will also match. Placing wildcards in any other position is

not supported.

NOTE: if a server has one Internet IP address and multiple server names, and if one of the

names is defined here, accesses to any one of the server names will also match this rule.

Protocol

and Port

This setting specifies the IP protocol and port of traffic that matches this rule. You may

select common protocols from the Protocol Selection Tool drop-down menu.

USER MANUAL

Peplink Balance Series

Algorithm

This setting specifies the behavior of the Peplink Balance for the custom rule.

One of the following values can be selected:

 Weighted Balance

 Persistence

 Enforced

 Priority

 Overflow

 Least Used (not applicable to Balance 20/30/30 LTE)

 Lowest Latency (not applicable to Balance 20/30/30 LTE)

The upcoming sections detail the listed algorithms.

Terminate Sessions

on Link Recovery

This setting specifies whether to terminate existing IP sessions on a less preferred WAN

connection in the event that a more preferred WAN connection is recovered. This setting is

applicable to theWeighted,Persistence, and Priority algorithms.

By default, this setting is disabled. In this case, existing IP sessions will not be terminated

or affected when any other WAN connection is recovered.When this setting is enabled,

existing IP sessions may be terminated when another WAN connection is recovered, such

that only the preferred healthy WAN connection(s) isused at any point in time.

14.2.1 Algorithm: Weighted Balance

This setting specifies the ratio of WAN connection usage to be applied on the specified IP protocol

andport. This setting 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

theWAN connection relative to the total weight.Use the sliders to change each WAN’s weight.

For 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%

14.2.2 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, for security reasons, many e-banking and other secure

websitesterminate 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

USER MANUAL

Peplink Balance Series

address change.

The 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 the 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 PeplinkBalance, 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, eliminating the issues mentioned above.

There are two persistent modes:By SourceandBy 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 loads

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 Autoin Load Distribution, the weights will be automatically adjusted according to

each WAN’s DownloadBandwidth, which is specified in the WAN Settings page (see

sectionConfiguring the WAN Interface(s)). If you chooseCustom, you can customize the weight of each

WAN manually using the provided sliders.

14.2.3 Algorithm: Enforced

This setting specifies the WAN connection usage to be applied on the specified IP protocol andport. This

setting is applicable only whenAlgorithm is set toEnforced.

Matching traffic will be routed through the specified WAN connection, regardless of the health check

status of the WAN connection.

Starting fromFirmware 5.2, outbound traffic can be enforced to go through a specifiedSpeedFusionTM

connection. (Available onthe Peplink Balance 210+)

14.2.4 Algorithm: Priority

This setting specifies the priority of the WAN connections used to route the specified network service. The

USER MANUAL

Peplink Balance Series

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 SpeedFusionTMconnection(s).

By default, VPN connections are not included in the priority list. (Available on the Peplink Balance 210+)

Tip

Configure multiple distribution rules to accommodate different kinds of services.

14.2.5 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 used.

14.2.6 Algorithm: Least Used

(Available onthe Peplink Balance 210+)

The traffic matching this rule will be routed through the healthy WAN connection that is selected in

Connectionand has the most available download bandwidth. The available download bandwidth of a

WAN connection is calculated from the total download bandwidth specified on the WAN Settings page

and the current download usage. The available bandwidth and WAN selection is determined every time

an IP session is made.

14.2.7 Algorithm: Lowest Latency

(Available onthe Peplink Balance 210+)

USER MANUAL

Peplink Balance Series

The traffic matching this rule will be routed through the healthy WAN connection that is selected in

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 uplinkcan be higher than that of a 2M down /2M up linkbecause the overall

round trip time is lengthened by its slowerupload bandwidth, despite its higher downlink speed.Therefore, this

algorithm isgood for two scenarios:

· All WAN connections are symmetric; or

· A latency sensitive application must be routed through the lowestlatency WAN,regardless the WAN’s

available bandwidth.

14.2.8 Expert Mode

Expert Mode is available for advanced users.To enable the feature,

click on the help icon and click turn on Expert Modeį

InExpert Mode, a new special rule,SpeedFusionTM Routes, is displayed

inthe Custom Rules table.This rule represents all SpeedFusionTM

routes learned from remote VPN peers. By default, this bar is on the top

of all custom rules. This position means that traffic for remote VPN

subnets will be routed to thecorresponding VPN peer. You can create

custom Priority or Enforced rules and move them above the bar to

override the SpeedFusionTMroutes.

Upon disabling Expert Mode, all rules above the bar will be removed.

15 Inbound Access

Inbound access is also known as inbound port address translation. On NAT WAN connection, all inbound

traffic to the server behind the Peplink unit requires inbound access rules.

By the custom definition of servers and services for inbound access,Internet users can access the servers

behind PeplinkBalance. Advanced configurations allow inbound access to be distributed among multiple

servers on the LAN.

Important Note

Inbound

access applies only to WAN connections that operate in

NAT mode. For WAN connections that operate

inDrop-in mode or IP forwarding, inbound traffic is forwarded to the LAN by default.

15.1 Definition of Port Forwarding

(Available onthe Peplink Balance 20/30/30 LTE)

does not take effect: the Peplink Balance disregards the other parameters of the rule.

Service Name

This setting identifies the service to the

system administrator.

Valid values for this setting consist

of only alphanumeric and underscore “_” characters.

USER MANUAL

Peplink Balance Series

IP Protocol

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 the Peplink Balance via the specified protocol

at the specified port(s) is forwarded to the LAN hosts specified by the Servers setting.

Please seebelow 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 remain manually modifiable.

Port

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 the 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 the 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 Range: traffic that is received by the 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 Ports 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.

For example, with IP Protocol set to TCP, and Port set to Port Mapping, Service Port 80, and

Map to Port 88, TCP traffic on Port 80 is forwarded to the configured servers via Port 88.

(Please see below for details on the Servers setting.)

Range Mapping: traffic that is received by the Peplink Balance via the specified protocol at the

specified port range is forwarded via a different port to the servers specified by the Servers

setting.

parameters of the rule.

When No is selected, the inbound service rule does not take effect. The Peplink Balance will

disregard the other parameters of the rule.

Service Name

This setting identifies the service to the System Administrator.Only alphanumeric and the

underscore “_” characters are valid.

Protocol

The IP Protocol setting, along with the Port setting, specifies the protocol of the service as

TCP, UDP, ICMP or IP.Inbound traffic that matches the specified IP protocol and Port(s) will

be forwarded to the LAN hosts specified by the Servers setting.

USER MANUAL

Peplink Balance Series

Upon choosing a protocol, the Protocol Selection Tool drop-down menu can be used to

automatically the Port information of common Internet services (e.g. HTTP, HTTPS, etc.).

After selecting an item from the Protocol Selection Tool drop-down menu, the Protocol and

the Port number will remain manually modifiable.

Port

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 the Peplink Balance via the specified protocol is

forwarded to the servers specified by the Servers setting.

For example, ifIP Protocol is set to TCP, and Port is set to Any Port, then all TCP traffic will

be forwarded to the configured servers.

Single Port: traffic that is received by the 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, if IP Protocol is set to TCP, Port is set to Single Port, andService Portis set to

80, then TCP traffic received on Port 80 will be forwarded to the configured servers via Port

80.

Port Range: traffic that is received by the 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, ifIP Protocol is set to TCP, Port is set to Port Range, and Service Portset to

80-88, then TCP traffic received on ports 80 through 88 will be forwarded to the configured

servers via the respective ports.

Port Mapping: traffic that is received by the Peplink Balance via the specified protocol at the

specified port is forwarded via a different port to the servers specified by the Servers setting.

For example, ifIP Protocol is set to TCP, Port is set to Port Mapping, Service Portis set to

80, and Map to Portis set to 88, then TCP traffic on Port 80 is forwarded to the configured

servers via Port 88.

(Please see below for details on the Servers setting.)

Range Mapping: traffic that is received by Peplink Balance via the specified protocol at the

specified port range is forwarded via a different port to the servers specified by the Servers

setting.

Inbound IP

Address(es)

This setting specifies the WAN connections and Internet IP address(es) from which the

service can be accessed.

Included

Server(s)

This setting specifies the LAN servers that handle requests for the service, and the relative

weight values.The amount of traffic that is distributed to a server is proportional to the weight

value assigned to the server relative to the total weight.

Example:

With the following weight settings on a Peplink Balance:

USER MANUAL

Peplink Balance Series

· demo_server_1: 10

· demo_server_2: 5

The total weight is 15 = (10 + 5)

Matching traffic distributed to demo_server_1:67% = (10 / 15) x 100%

Matching traffic distributed to demo_server_2:33% = (5 / 15) x 100%

15.3.2 UPNP / NAT-PMP SETTINGS

UPnP and NAT-PMP are network protocols which allow a computer connected tothe LAN port to

automatically configure the router to allow parties on the WAN port to connect to itself. That way, the

process of inbound port forwarding becomes 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

trust the computers connected tothe LAN ports.

When the options are enabled, a table listing all the forwarded ports under these two protocols can be

found at Status > UPnP / NAT-PMP.

15.3.3 Definition of DNS Records

(Available on Peplink Balance 210+)

The built-in DNS Server functionality of the Peplink Balance facilitates inbound load balancing. With this

functionality, NS/SOA DNS records for a domain name can be delegated to the Internet IP address(es) of

the Peplink Balance. Upon receiving a DNS query, the Peplink Balance can return(as an “A” record) the

IP address for the domain name on the most appropriate healthy WAN connection.It can also actas 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 namewww.mycompany.comis delegated to the WAN2 Internet IP

addresses of the Peplink Balance.

Upon receiving the DNS query, the Peplink Balance returns (as an “A” record) theIP address for

www.mycompany.com on WAN1 because WAN1 is the most appropriatehealthy link.

PTR records are created along with A records pointing to Custom IPs. Please refer to Section for details.

For example, if you created an A record www.mydomain.com pointing to 11.22.33.44, then a PTR 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 for PTR records to function, youalso need to create NS records. For example, if the IP address

range 11.22.33.0 to 11.22.33.255is 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.

15.4 Reverse Lookup Zones

Reverse lookup Zones can be configured in Network > Inbound Access > DNS Settings.

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, 2, ... 254 respectively.
