Same IP through cable router

[g30hd3]

Hello to all members!

I've been using whatismyip for quite some time now and it has never failed me. Recently I've switched over to Comcast HS Cable internet service (20mbps dynamic) and this annoyance started showing up. No matter what device I use to log onto whatismyip.com it would show the same exact IP (for example; 68.180.15.177). I've tried many online games that is connectable over IP, which all have failed to connect, so I can safely rule out that the IP is not of my of my NIC. Please help?

PS: I'm looked up on a netgear wireless/wired router.

Going from memory here, I'm not sure that IP is going to work. At least, not the way that games use IP.

I haven't done a PC game in a long time, and have enjoyed my XBox360 since it was released to market. But I recall my PC copy of Half-Life had an IP option *and* an Internet option. The IP option never worked through routers, as I recall. This was not a problem in the game; it was designed that way. If you wanted to play HL over the Internet, you had to use the "Steam" online service setup by Valve Software.

Either your game software is setup this way, or you may need to configure port forwarding on your broadband router. Obviously, though, you'd need to find out what ports the game is using.

It might help if you posted the name of a game or games you are trying to use. You have to bear in mind that, for some games, a system on the other end may need to connect back to your system on a specific port. Transmissions between systems on the Internet consist of an IP address and port combination. So the other system may try establishing a connection back to your IP address, but if your router isn't configured to "port forward" that data to your system, the transmission will be blocked at the router.

If you provide the name of the game or games you are attempting to use, someone on the forum may be able to tell you which ports need to be port forwarded through your router.

The port forwarding won't happen automatically, if the system on the other end isn't simply responding back to the port from which your system sent data and that is the case with some games and other applications. You have to configure the router to forward data addressed to the the port on which the system on the other end transmits to the IP address of your system and that address will normally be different than the one whatismyip.com sees for your router for a home user, since a home user's router usually performs Network Address Translation (NAT). I.e. the address the network card on your computer will be different than the one whatismyip.com sees.

Also, what is the model of your Netgear router?
