CBA850 Bridge Mode Setup?

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?

Do you have DHCP turned off on the IPPT port?

If its off then you should be getting the ip from att, I also assigned an ip from a subnet not in my setup for the IPPT port.

I use pFsense
