This section provides instructions for dialing into to your ISDN LAN Modem from a
remote location using either another LAN Modem or an ISDN modem, in order to
make configuration changes. In addition to another LAN Modem or ISDN modem,
you will need a Web browser, and any PPP dialer software, such as Windows

To dial into a LAN Modem from a remote location using another LAN Modem, do
the following:

Ensure that the two LAN Modems are on different networks.
For instance, one LAN Modem can be on the 192.168.1.x network, and the other
one can be on the 192.168.2.x network.

Create a Private Network entry for the remote router.
No user name or password is needed. You must use an arbitrary numbered WAN

Modem.
