The Port Forwarding Screen
The Port Forwarding screen is reached by the Port Forwarding link. The following is a sample screen.
Figure 25. The Port Forwarding Screen
This screen lists a number of pre-defined servers and allows users to define their own servers. Details of the selected server are shown
in the Properties area. The following table describes the fields on the Port Forwarding Screen.
Service
Service Lists a number of pre-defined and user-defined services. Details of the selected service are shown in
the Properties area.
Properties
Enable Enables/Disables Port Forwarding for this service, as required.
PC (Server) Selects the computer to be used as the server for this service. The computer must be running the
appropriate Server software.
My PC is not listed If the computer uses a fixed IP address, and is not in the list, click here and add it using the PC Database
menu option.
Protocol Selects the protocol (TCP, UDP or TCP/UDP) used by the service.
Internal (LAN)
Ports
Enter the range of port numbers that the server software is configured to use.
External (WAN)
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 computer 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.
Buttons:
Defaults Deletes any user-defined servers, and sets the pre-defined servers to use their default port numbers.
Disable All Causes the Enable setting of all entries to be set Off.
Delete Deletes the current server entry. Note that the pre-defined servers cannot be deleted; only those servers
that are user-defined can be deleted.
Clear Form Clears all data from the Properties area.
