Port Forwarding

Port forwarding enables you to make services from applications in your local network avail-

able to Internet users as well. The router can use a specific port to automatically forward

incoming requests from the Internet to a PC in the local network and thus set up a virtual

server, for example to publish your Internet page on your own Web server.

Internet services are generally addressed via defined port numbers. The router requires a

mapping table for the port numbers in order to divert the service requests to a PC that

actually provides the service. You can create these on this Web page.

Precondition: NAT is activated.

¤ Open the following Web page: Router Settings ¢ Internet ¢ Address Translation (NAT)

¢ Port Forwarding.

¤ Select a service from the Predefined Applications list.

¤ In the Local IP Address column, enter the private IP address for the PC to which the

requests should be forwarded and click Add.

¤ Repeat the previous step as necessary for further port forwarding.

If the required service is not in the list, you will have to enter the port forwarding manually.

¤ Select the protocol used by the service from the Protocol list.

¤ Enter the port number for the service under Public Port.

¤ Under Local Port enter the number ports on the PC to which the service requests should

be forwarded.

¤ Enter the IP address for the PC in the local network in the Local IP Address field.

¤ Repeat the previous step as necessary for further port forwarding.

¤ Click Set to apply the settings.

Please note:

– Deactivate the Enabled field to temporarily deactivate the port forwarding.

– Click Delete to remove a forwarding action from the list.

– If you want operate your base station phone's Web configurator from a different network

remotely, you have to forward the HTTP port 80 (Public Port) to the port 80 (Local Port) of the base

station phone, and permit remote management on the phone Web configurator (page 88).
