I just switched to Comcast 2 days ago from Verizon DSL. I have called, lost count, trying to resolve this issuse and its like the Comcast people have no idea what I am talking about.
History, I had Verizon DSL which fed into my D-Link DIR-655 that has my port forwarding setup. The DIR-655 allows me to run dlinkddns service within the router to report the (Dynamic) IP number from Verizon that changes from time to time.
Everything worked great, until Comcast removed the DSL modem and installed thier Wireless Gateway, an Arris TG862G. First clue something is wrong, when I log into the D-Link Dynamic DNS website to check my account, it is showing my home IP address as 10.0.0.3, when I am at home that is the IP being assigned to the DIR-655 from the Comcast modem. So it is communicating good, back to the D-Link website, and my internet works fine at home. The problem is the dlink dns name I have established is naturally getting the wrong IP of 10.0.0.3 which is privitized, when it should be 22.214.171.124 at that time.
I called yesterday and asked them to change the modem to Bridge mode, which they say they did, the problem still exists.
Self troubleshooting, I connected one of my devices that operates on port 2000 directly into the Comcast modem, logged into the modem and setup port 2000 to forward to IP 10.0.0.50, and it worked. I can connect to the device, but I have to use the current IP Comcast has assigned to the modem.
So what am I missing?
I want my D-Link Dynamic DNS to report the current Comcast public IP address so it resolves by dns name.
I want my D-Link DIR-655 to handle the routing and port forwarding.

You have a *double NAT*. Call the gateway support team at this number to get it bridged; 1-800-363-2416.
They'll get it right.

Called the Gateway Team, and they understood exactly. I said they had put the modem in bridge mode yesterday, and the nice lady said "Nope, let me take care of that, done" Dam she was good. I checked the D-Link site and there is the correct address. So when I get home I can really test it out.
Calling that main support number is a pain in the you know what, they had no clue what I was trying to do.
