HG622 configuration for bridge mode

Purchased an HG622 via ebay. It's configured for IP Routed and NAT. I'd like it to pass the public IP (talktalk fibre) via LAN1 port to my Draytek router, and I'd still like to be able to log in via either LAN2 or SSID1 (wifi) to manage the HG622 and check/download statistics.

I am not sure exactly how to configure things on the HG622 to allow this to occur. I'm still seeing 192.168.x.x IP address in the Draytek router LAN1 configuration rather than the talktalk public IP. What do I need to change?

Thanks.

Anyone? I don't wish to use double NAT. It messes up VoIP connections. I haven't found an online guide explaining how to put this into the correct bridge mode.

This is the setup for bridging for the HG612, hopefully you can adapt (slightly) for the HG622.

Router plugged into Port1 then PPPoE's to get a connection.
