OS: Windows 7 Home
Network Devices: AT&T 2wire 2801HGV modem/router and Netgear N570 WNDR4000 Router
Ports Forwarded:777 and/or 31337
Purpose: Terraria Server Hosting
Background Info: Our ISP has recently been switched from Comcast DSL to AT&T. As a standard, AT&T replaced our old modem with their 2WIRE. All three of the computers on the network had been connected to the Netgear router. With the installation of the 2wire, they presumably still are. This had been done at another house, and the "competition" of the 2wire with the original router had caused problems. The 2wire their also refused to port forward.
I am not a networking expert so, if information is missing, let me know. Here's what I did: First of all, I checked that the port 7777 was allowed through Windows Firewall and made sure it was an Inbound rule. Then,I went into the 2wire router. At the time I thought my pc was assigned to it; I've since learnt that it probably wasn't. I configured the router to forward port 7777 (I left the application type blank) for what I thought was my computer; it was actually the Netgear router. I tried doing the same using my internal ip: 10.0.0.3; I did the same using, for whatever reason, my external ip: 184.108.40.206. Then I did the whole process over using port 31337. None of this worked, and neither did allowing all applications through the router firewall (DMZplus mode). Then I entered my internal ip into the address bar of chrome; it took me to the Netgear router. First of all, and this may be important, it said that my pc wasnt assigned to the Netgear; this has happened twice since and it confuses the hell out of me. I was somewhat relieved, because it's much simpler to port forward with Netgear's UI, and I had never had problems with it before. Sadly, both ports remain closed despite the adjustments. As an addendum, I also seem unable to connect to another network which is successfully forwarding the 7777 port. Their Netgear router is successfully doing what mine refuses to.
At this point, I have no clue what the problem is; I suspect it may have something to do with the combination of a router and modem/router. I can't get help from either AT&T or Netgear because the problem is, on one hand, "out of their scope" and, on the other, a "$129 Problem". Any help at all would be greatly appreciated.
