Port Forwarding C7000v2 and R630
I'm setting up a web server. The computer I'm using is hardwired to a router R630, The R630 is hardwired to my cable modem C7000v2. Do I need to do anything to the cable modem, or just do port fo...
R630 isn't a model. It usually has 4x numbers. Maybe you have the R6300?
A couple things.
Is the C7000 running in router mode?
Is the R630* in access point mode or in router mode as well?
Otherwise you're in a double nat.
A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions.
2. Leave the modem/gateway in router mode but put the 2nd router's IP address into the gateway's DMZ. This forwards the data to the 2nd router. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the 2nd router into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features. Seems to be what you'd want to do.

For future cable modem help and information, Netgear has set up a community forum specifically for the Cable Modem products. Most of the people who watch that forum are more likely to have experience with Cable modems and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:

Thanks for any help.
