Netopia R910 User Reference Manual page 59

Select Service. A pop-up menu of services and ports appears.
I
Service...
Local Server's IP Address:
5. Select any of the services/ports and press Return to associate it with the address of a server on your local
area network. For example, if we select www-http 80, press Return, and type 10.0.0.2, the Netopia R910
redirects any incoming traffic destined for a Web server to address 10.0.0.2.
Some services such as Timbuktu require the export of multiple TCP ports. When you associate Timbuktu
with a local server (or Timbuktu host) all of the major Timbuktu services are exported, i.e., Observe,
Control, Send, and Exchange.
Note: If the TCP port of a service you want to use is not listed, you can add it by selecting Other... on the
pop-up menu.
