Is anyone else here using Shaw with the Arris XB6 modem is bridge mode? If so, have you asked Shaw for a second WAN IP and gotten it? I've been running my modem like this for many months now without issue, but my coworker is getting the run-around from Shaw, saying he already has two IPs in use on his modem. Well it seems that the XB6, even in bridge mode still holds its own WAN IP, separate from the one that is issued to the clients router. So in my case I actually have three IPs, one is on the WAN interface of the modem, the other two go to DHCP clients on my routers. But in my coworkers case, Shaw says that this means he needs to be allocated a third IP, which is an extra $10/month.
So if you're running an XB6 in bridge mode could you do me a favour and go to the modem admin page (10.0.0.1, yes it's still active, even in bridge mode) and go to Gateway > Connection > Shaw Network and see if your modem has a WAN IP that is different than your router has, and if you have two WAN IPs like me, is the modem WAN IP different than both of them?
