16. Connect the DIVA LAN ISDN Modem to the LAN. Do this by connecting any one of the DIVA LAN
ISDN Modem’s ETHERNET ports to a port on your LAN hub.
If your hub has a cross-over switch or cascade port, you can use the supplied blue Ethernet cable to make
this connection. If not, you will need a special cross-over Ethernet cable to make this connection.
Try connecting the supplied blue cable to the hub, if the green Ethernet light on the DIVA LAN ISDN
Modem does not light up, you need a special cross-over cable.
17. Press the Reset button on the back of the DIVA LAN ISDN Modem.
18. Restore your computer’s network configuration settings and reconnect it to the LAN.
19. Start your Web browser and enter the new IP address you assigned to the DIVA LAN ISDN Modem. Your
browser should display the Log In page.
20. You may need to adjust the configuration settings of the computers on your LAN. See “Adjusting
configuration settings on the LAN” on page 114 for complete details.
Adjusting configuration settings on the LAN
Depending on your setup, you may have to adjust configuration settings on your computers in order to
communicate with the DIVA LAN ISDN Modem. Due to the diversity of networking equipment and
topologies, this section can only cover several of the most common setups. If you setup is more complex,
contact your network administrator, or other support person to help you with your installation.
If your LAN uses static addressing
Configure TCP/IP on each computer that will communicate with the DIVA LAN ISDN Modem as follows:
• Set Default Gateway to the address of the DIVA LAN ISDN Modem.
• Set DNS Server to the address of the DIVA LAN ISDN Modem.
If your LAN has a DHCP server
Configure your DHCP server to return the address of the DIVA LAN ISDN Modem as the Default Gateway
and DNS Server to all clients.
If your LAN has a router
If you have a router on your LAN, it is likely configured as the default gateway for your computers. In this
case, you will need to configure the routing table on your router to re-direct the appropriate traffic to the DIVA
LAN ISDN Modem. And add a route on the DIVA LAN ISDN Modem to direct appropriate traffic to the
router.
Consider the following example:
• Traffic from LAN A addressed to LAN B is forwarded by the router to LAN B.
• Traffic from LAN A addressed to the Internet needs to be forwarded by the router to the DIVA LAN ISDN
Modem. This requires you to configure a route on the router.
• Traffic from the Internet to LAN B needs to be forwarded to the router. This requires you to configure a
route on the DIVA LAN ISDN Modem. No route is needed for traffic to LAN A.
