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.

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.

Still true.
- SeanDoughtieJul 22, 2019AspirantEveryone keeps saying it’s “only a modem”; even tech support. Which is what I want. There is defiantly NAT going on. Even the docs say to put my router into bridge mode which makes all router functions useless. Even the router says there is a double NAT problem...
It would appear that the ‘PnP’ part of this only plays nice with NETGEAR routers.
It’s going back if I can’t get this resolved.
