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.

ì In the Applications & Gaming menu, select Port Forwarding.

You can choose a service from a list of predefined applications or create an entry man-

ually.

ì Select the add box to activate the fields in a row to create a new entry.

ì If more than one interface is configured select the Interface for which the port for-

warding should apply from the option menu.

ì Select the required application from the Predefined applications list.

ì Enter the IP address of the PC that provides the service in the Local IP field. How to

determine the IP addresses of the individual PCs is described in chapter "Local net-

work configuration" on page 36.

If the application you require is not in the list, you must manually enter the relevant data

on the screen:

ì Select the add box to activate the fields in a row to create a new entry.

ì If more than one interface is configured select the Interface for which the port for-

warding should apply from the option menu.

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.
