FWIW I'm not sure it is bridged, seems strange they would do that without telling the user...
I will agree that Comcast should not have put the OP's gateway into bridge mode without notification, but since the OP's external router has a WAN IP address of 71.199.xx.yy, there is no doubt that the router is connected to a bridge, not a gateway.--
