User's Manual

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:

● 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%

UPnP / NAT-PMP Settings

UPnP and NAT-PMP are network protocols which allow a computer connected to the 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 to the LAN ports.

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

found at Network>Services>UPnP / NAT-PMP.

11.5.3 DNS Settings

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
