Hi
My draytek 2927 ax is behind my ATT rgw210-700. I'd prefer the ATT router to be in IP Passthrough mode since this router does not support full bridge mode.
I came close to getting it working.
For the ATT router, I reviewed this article:

In addition to the settings mentioned in this article, I also switched off its DHCP server mode.
I made several changes to Draytek's WAN settings:
These changes are::
Under WAN -> Internet Access -> Static or Dynamic IP tab:
1) WAN detection mode: 'Pin Detect' or 'Aways On'
2) Enabled 'Specify IP address' and specified the public IP/gateway IP. This makes it seem like my router has a static IP - in reality, it is dynamic.
3) 'DNS Server IP address' : for this setting I set it to cloudflare - 1.1.1.1, 1.0.0.1.
After rebooting...
