CBA850 Bridge Mode Setup?

Post by miles267 » Thu Oct 29, 2020 4:28 pm

Hi - I just got a CP CBA850 and am using with AT&T LTE. However I'm trying to figure out how to put LAN port 2 in full bridge mode so that I can set it up in front of an existing Untangle router without having double NAT.

Currently, I have LAN port 2 setup in IP Passthrough mode and the Untangle interface setup for DHCP, however the CBA850 is assigning this WAN interface a 10.x.x.x private IP address.

Is it possible to setup CBA850 for IP Passthrough mode so that it disables NAT altogether?

Thanks.

Is this just a matter of AT&T's cellular network? They NAT all their public IP addresses as private address range?
