Service
This lists a number of pre-defined Services, plus any Services you
have defined. Details of the selected Service are shown in the
"Properties" area..
Properties
Enable
Use this to Enable/Disable Port Forwarding for this Service, as
required.
PC (Server)
Select the PC to be used as the Server for this Service. The PC must
be running the appropriate Server software.
Protocol
Select the protocol (TCP, UDP or TCP/UDP) used by the Service.
Internal Ports
Enter the range of port numbers which the Server software is
configured to use.
External Ports
Traffic from the Internet using this range of port numbers will be
sent to the selected Server. These ports are normally the same as
the Internal Port Numbers. If they are different, this device will
perform a "mapping" or "translation" function, allowing the server
to use a different port range to the clients. Using this feature allows
the server to distinguish traffic from the WAN from traffic on the
local LAN by using the port number, rather than having to check IP
addresses.
