How do I make my BGW210 a modem, instead of a router?

Put the gateway in pass through mode to allow the third party router to handle all of the router and WiFi duties.

Thanks.

I was attempting that, but my intended router failed.

I made many changes before I discovered the failed hardware.

I have now set

IP Passthrough

Allocation Mode: Passthrough

Passthrough Mode: DHCPS-fixed

However, when I do a traceroute I see 192.168.1.254 instead of my public IP address.

Are all my ports (UDP/TCP) being 'passed through' or is there some 'filtering' still happening?

Regards, Chuck

Someone else who has AT&T fiber and knowledge of the pass through mode will have to answer that. I don't use AT&T as my ISP so I use my own hardware with zero issues.
