For example, if IP Protocol is set to TCP, Port is set to Single Port, and Service Port is 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, if IP Protocol is set to TCP, Port is set to Port Range, and Service Port set 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, if IP Protocol is set to TCP, Port is set to Port Mapping, Service Port is set to
80, and Map to Port is 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:
● 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.
