Bridge Mode?
Does this modem come from the factory in Bridge mode? I'm having problums port forwarding. I have set up the netgear router (AC1200) with no luck on any ports. I did the activation thru Xfinity.
Again, the CM series modems are modems only. There is NO NAT or router functions here. You only get built in router or NAT functions with C series modems.
Possible your main host router isnt' configured correctly. Contact the Mfr of the main host router for additional help and support.
If the CM modem isn't working, try a different CM modem. The CM1000 would be a better modem. The CM500 is an intel based chip set modem which there are known problems with this chip set Mfr:
The CM1000 is a broadcom based chip set modem.
