Routing (NAT?) and IP conflicts

post #1 of 6
Thread Starter 
Blunt and straight to my problem: my brother and I both want to play the same game online, but when we try to access the same server at the same time we get an IP conflict.

Now, I'm no networking wiz, hence the creation of this thread, but is that due to NAT? It seems the most logical answer due to the definition and function of NAT.

Does anyone know how I can stop this or prevent it in the future? I heard that common higher-end routers fix the IP conflict problem, but I want to make sure I know how this stuff works before I go and fork out money for a new router and modem (my current setup is a hybrid router/modem in one).

I'm currently in the middle of reading a few guides and explanations I found on the web, starting with the grc.com article on NAT, but I can't be certain any of them will address the problem, therefore... HELP! heh.

What game?? There are some games that do not allow two simultanious connections from the same IP. It IS becasue of NAT, but there is no way around it.

Counter-Strike and Starcraft both have not let us play together.

We've tried no other games so far as my brother only plays games that have been widely advertised =\\

You're only getting one external IP, so if these games don't allow multiple connections from the same IP I don't know of anything you can do about it.

Still, that doesn't seem like a likely cause for not being able to play these games as it would mean that two people on the same subnet could not play on the same server on a different subnet, and that doesn't seem likely at all.

Well, I'll get my brother to try a few recently released games with me tonight, but I know that he and I can't access the same server online at the same time. Stupid NAT.... yet... lovely NAT.

I hate NAT, but it's so EFFICIENT! DARN IT!

Counter strike makes no sense. I play with my bro ALL the time behind the same router on their servers. So there's somethign else going on there. As far as starcraft goes, are you using the same CD Key?? I know that they wont let you on battlenet if they detect multiple access attempts from the same key.
