Strange I've just tested mine, I can also access the Vigor's web GUI via 192.168.2.1. I didn't think this was possible with it running in bridge mode? Not that's it's a problem for me.

What router are you using?

Asus RT-AC68U with firmware 3.0.0.4.378.6975.

I tried googling again, I did before originally posting but I got lucky this time with this...
http://www.dslreports.com/faq/14772
Which shows a number of ways, using a switch (as suggested by fchef) or looping the router back into itself (no new hardware required but I lose a couple of available LAN ports), that will allow simultaneous access to the internet and the modem interface.

Alternatively, by setting my router to a static IP address (192.168.2.10 worked) rather than a PPPoE connection, I can access the modem from the PC, but of course I can't have simultaneous internet access.
