The next step in configuring the Frame Relay to ATM Converter is adding the default gateway route. Since
the WAN IP address of the 3086FR modem at the CO site is 192.168.101.2, this will be the gateway for the
3086FR modem at the CPE site, the modem we are currently configuring.

Create a New IP Route

3. Enter 192.168.101.2 in the box adjacent to Gateway.
