Port Forwarding allows you to direct incoming traffic from the WAN
side (identified by protocol and external port)to the internal server
with a private IP address on the LAN side. The internal port is required
only if the external port needs to be converted to a different port
number used by the server on the LAN side. A maximum of 32 entries can
be configured.
Select the service name, and enter the server IP address and click "Apply"
to forward IP packets for this service to the specified server. Note: Modifying the Internal Port Start or Internal Port End is not recommended.
If the External Port Start or the External Port End changes, the Internal Port Start or
Internal Port End automatically changes accordingly.
