Configuring the remote modem/router
Adding the Remote Phone addressing
The DIVA LAN ISDN Modem has built-in network address translation (NAT) to allow multiple hosts to
use the ISDN connection to the Internet and to provide limited security for those hosts. Please follow the
following steps to add the Remote Phone address and UDP Port to the NAT mapping.
1. On the user's PC (assuming it's properly configured to use the modem), open a Web browser and,
in the address field, enter the IP address of the modem. By default, that address is 192.168.1.1.
2. The Web browser will load the configuration screen and should ask for your password. Enter the
system password if required.
3. You should now be at the main Configuration menu. To allow the traffic bound for the phone
through the modem you will need to create a static NAT mapping (in addition to the following, you
can find instructions for this in the DIVA LAN ISDN Modem User's Guide.)
• Click on IP.
• On the IP menu, click NAT Static Mappings.
• On Map 1, under the Protocol choose UDP.
• Under the server port, enter the UDP port the Remote IP Feature Phone will be using.
For the server IP address for Map 1, enter the IP address of the phone.
• Now click on Save, then click on Reset.
4. When the modem comes back on-line, proceed to "Connecting the Remote Phone" (page E.1).
