Port Forwarding
If you configure Port Forwarding, the Gigaset SE551 WLAN dsl/cable 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 on
the local network remain protected.
Internet services are addressed via defined port numbers. The Gigaset SE551 WLAN dsl/
cable needs a mapping table of the port numbers to redirect the service requests to the
server that actually provides the service. For this, Port Forwarding has to be configured.
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
Click the Add button. The data for the required service is entered on the screen.
ì
Select the option in the Enabled column.
If the application you require is not in the list, then you must enter the relevant data on
the screen manually:
ì
Select the protocol of 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.
