You can use the NAT settings to configure the Gigaset SE587 WLAN dsl to carry out the
following tasks:
u
Set up the Gigaset SE587 WLAN dsl as a virtual server by configuring Port Forward-
ing (see below).
u
Open the NAT firewall for a selected PC (page 29).
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.
