RAXE450 anywhere access does not work using IP Passthrough enabled on AT&T BGW320

[1yonger]

I have AT&T fiber through BGW320 device. 

I installed RAXE450 and enabled IP passthrough on the BGW320. 

Remote access using Nighthawk anywhere access does not work with IP passthrough. No issues locally. 

I suspect app cannot see the router with IP passthrough. 

Any workaround on this or is this a permanent annoyance with BGW320 (IP passthrough)?

What is the firmware on the RAXE450? Which app? (Android? iOS?)

In what way "does not work"?

AT&T seems to have the same strategy as BT in the UK, it supplies gateways that are impossible to configure as users might like. No true bridge mode.
