Technicolor CGA4131COM port forwarding broken
I am trying to forward several ports with this gateway, i.e. port 25, but none of the port forwarding appears to work. I have verified that the ports are open on my server. I have port forwarding set up with both the IPv4 and the IPv6 address but the port is not getting forwarded to the 10.1.10.X address behind the firewall. I have verified that the address is correct.
Note that I did not have these problems with my previous Cisco modem.
Sadly I had to change to this modem due to adding voice service.

There are so many port forwarding posts, none answered. How did this get resolved?

Lame response from Comcast above.
It has nothing to do with "internal networks" and everything to do with port forwarding being COMPLETELY BROKEN.
I actually had three (3) Comcast modems (mid end and high end) ALL fail for the most basic setup today. Finally got one to configure port forwarding, then it stopped workign one hour later, then it became inoperable for even changing config.
It's not you, it is Comcast bugs in the modems.
