Port Forwarding - Gigaset SX553 WLAN dsl First Steps

Port Forwarding

If you configure Port Forwarding, the Gigaset SX553 WLAN dsl outwardly assumes the
role of the server. 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 SX553 WLAN dsl
needs a mapping table of the port numbers to redirect the service requests to the serv-
ers that actually provide the service.
Port Forwarding is configured for this purpose.
ì
To set up port forwarding for a service, select Port Forwarding from the
Advanced Settings – Internet – Address Translation (NAT).

Activate Enabled by clicking the check box.

ì
Click the Delete button to delete an entry.

to be forwarded.
