Port Forwarding

If you configure Port Forwarding, the Gigaset SE587 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 SE587 WLAN dsl
needs a mapping table of the port numbers to redirect the service requests to the serv-
ers that actually provide the service.
