We currently have a T1 connection to our data center that is setup as PPP. We are migrating away from this and connecting to our customers LAN using the Eth 0/2 port on the Adtran. When configuring the IP address on Eth 0/2, the AOS adds an IP Route that direct the subnet to 0.0.0.0. This doesn't allow the traffic on Eth 0/2 to reach the default gateway of the LAN.
