Summary

This article describes how to configure the CBA850 for Inline IP Passthrough mode. In this mode the CBA850 terminates the Wired WAN connection and controls failover to the cellular network for the CPE router. This can be very useful when the failover control is not desired at the CPE router or the CPE router does not have more than one Ethernet WAN interface.   User-added image
NOTE: The WAN interface on the CPE Router must be set to receive a DHCP IP address from the CBA850 in order for failover to function while the router is in IP Passthrough Mode.
