Custom Port Forwarding

: If there is no pre-defined Port Forwarding Rule for a particular

application, a user rule can be created which defines the required Ports, Protocols and Port

forwarding rules. Click the Custom Port Forwarding button and the following screen will pop-up.

To create a custom rule you will need to know the specific port number and port type that the

application requires. Some applications specify a range of ports in which case you will need to

know both the starting and ending port numbers in the range, which are mapped by the start port

and end port fields.

The Port Map specifies the internal port that the data will be directed to on the LAN Client. When

dealing with port ranges, the Internal Port will be the same as the first port in the range. When you

simply want to forward a single port from outside to inside, then all three fields (Port Start, Port End

and Port Map) will have the same port number.
