Port Forwarding

If you configure Port Forwarding, the Gigaset SX541 WLAN dsl outwardly assumes the
role of the servers. It receives requests from remote users under its public IP address and
automatically redirects them to local PCs. The private IP addresses of the servers in the
local network remain protected.
Internet services are addressed via defined port numbers. The Gigaset SX541 WLAN dsl
needs a mapping table of the port numbers to redirect the service requests to the server
that actually provides the service. Port Forwarding has to be configured for this purpose.
ì
To set up port forwarding for a service, select Port Forwarding in the
Address Translation (NAT) menu.
ì
Select the required application from the Predefined applications list.
ì
Select the option in the Enabled column.
ì
Click the Add button. The data for the required service is entered on the screen.
If the application you require is not in the list, you have to enter the relevant data on the
screen manually:
ì
Select the protocol for the service you are providing from the Protocol list.
ì
Under Public port, enter the port number of the service you are providing.
ì
In the Local port field, enter the internal port number to which service requests are
to be forwarded.
ì
In the Local IP address field, enter the IP address of the PC that provides the service.
