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.

CM series model modem are only modems. So no bridge mode. No built in router like the C series modems.

So this modem can not be put in Bridge mode? Therefor I can never port forward? I know it is not a router but if the modem is
not in bridge mode my router will not port forward because the modem is blocking. Thanks for the reply.

No, it has no other mode. It's always only a modem.
A modem+router (like a model Cxxxx) typically has a "bridge"
(modem-only) mode, but a modem-only (model CMxxx) is only a modem. If
you want to call that a "bridge" mode, you can, but that's the only mode
it has. You don't need to _put_ it into that mode.

It's a modem, not a modem+router. But why trust me? Visit
http://netgear.com/support , put in your model number, and look for
Documentation. Get the User Manual. Read.> [...] I'm having problums port forwarding. I have set up the netgear
> router (AC1200) with no luck on any ports.A modem-only device like a CMxxx should not affect port forwarding;
that's a router function. What, exactly, is your "the netgear router
(AC1200)"? "AC1200" is a speed, not a model. Look at the product
label. Firmware version?
What kind of problems? "problems" or "no luck" is not a useful
problem description. It does not say what you did. It does not say
what happened when you did it. As usual, showing actual actions with
their actual results (error messages, LED indicators, ...) can be more
helpful than vague descriptions or interpretations.Is there some actual problem which you are trying to solve?

Please post in the NG router forum for your model NG router.
Also review the user manual for your model NG router for configuration information.
Good Luck.

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:

It's going back. Everything works fine on the modem that I have that is about 10 years old. Just it's not longer supported by cox; though it still works.
It really is a poor product and a collosal waste of my time. I was on the phone with tech support for 40 minutes last night and they concluded it was the Apple Airport Extreme was the problem. Though it works fine with the old modem.
I will definately let bestbuy know it's a poor product also...

Ya, ok. Sounds like this is apple router issue. Probably a mis-configuration or incompatibility issue. The CM modem works for others so I doubt NG is entirely to blame.
Good Luck.
