Like Colin wrote already, the bridge is transparent for the netowrk. You 
get the IP address from the router, not from the bridge. Your initial 
post showed at the traceroute output that your router is at 192.168.0.1:

| 1  192.168.0.1 (192.168.0.1)  1.364 ms  6.244 ms  6.238 ms

If you want to connect to your router you should use 192.168.0.1 and not 
192.168.1.1.

Yes, the configuration is different as it uses static addresses 
according to the manual. But after you have finished the configuration, 
the GWU works in bridge mode and you get your address from the router 
via DHCP.
