ì In the Local port field, enter the internal port number to which service requests are

to be forwarded.

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

find out the IP addresses of the individual PCs is described in chapter "Local network

configuration" on page 36.

Example: The Web server has been configured to react to requests on port 8080. How-

ever, the requests from web sites enter the Web server via port 80 (standard value). If

you add the PC to the forwarding table and define port 80 as the public port and port

8080 as an internal port, all requests from the Internet are diverted to the service with

the port number 80 on the Web server of the PC you have defined with port 8080.

ì Select the del box to delete an entry.

ì Click Save Settings to apply your settings.

DMZ

You can set up a client in your local network to be a so-called "exposed host" (DMZ). Your

device will then forward all incoming data traffic from the Internet to this client. You can

then, for example, operate your own Web server on one of the clients in your local net-

work and make it accessible to Internet users.

As the exposed host, the local client is directly visible to the Internet and therefore par-

ticularly vulnerable to attacks (e.g. hacker attacks). Only activate this function if it is

absolutely necessary (e.g. to operate a Web server) and other functions (e.g. port for-

warding) are not adequate. In this case you should take appropriate measures for the

clients concerned.

ì In the Applications & Gaming menu, select: DMZ

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 DMZ

should apply from the option menu.

ì Enter the IP address of the PC that is to be enabled as DMZ in the Current Host IP

field.

ì Click Save Settings to apply your settings.

Note:

Only one PC per public IP address (interface) can be set up as a DMZ.
