Diablo 2 Connection problem

[epix]

I decided to play diablo 2 again after many years and I'm having trouble connecting to the d2 servers. When I try to log into any realm, it says "Unable to connect to Battlenet." I have windows 7 and an old linksys wrt54gs router. Here are the things I have done that haven't worked:

--Use port forwarding to open ports 4000 and 6112-6119. (portchecker says their open)
--Turned off my firewall on my router and computer
--set a static ip address for my computer
--put my computer's IP into DMZ

I can connect to the d2 servers if i connect my computer directly to my modem. But this isn't a great solution because I have 3 other computers that need the router. I'm average at computers, so please try to go step-by-step with your suggestions.

You're awesome. The first person i know to have connection troubles with Diablo 2 xD.

In any case, it doesn't seem to be computer or game related but rather you're firewall on the router. Try disabling NAT on you're router and try again. Changing the router might help (linksys isn't that great), but otherwise i have no solutions at the moment >>

How do I disable the NAT on my router? I don't know what that is. Can't seem to find it under my router's homepage

 

[Nenad]

NAT prevents outgoing ip's to connect to you're computer (a.k.a blocks outside connections, like pinging etc.). It should be under either security or settings and then NAT/firewall settings.

There's a Filter Nat Redirection, but that didn't do anything. I guess I'll have to hook up my PC directly to the modem for it to work and play when the family isn't using the internet

Setup > Basic Setup > Wireless > Edit Security Settings

Set gateway mode to router mode. Hopefully that works.

My first reaction is to say that your CD Key is banned, but seeing as you can connect directly through your modem, this is not the case. You can also try disabling security settings, but that opens your computer up for a whole 'nother can of worms.

I tried changing it to router mode too, but that didn't work. It's definitely not the CD key because I can connect thru the modem.

My friend gave me his WRT54G router, do u think that will help if I swap to it? Also he didn't give me an install disc, so how would I install without it?

Try swapping the router, that should help (seeing as how thats the problem). No install disc required for the router, just open the DNS address in you're browser after you connect the router (usually you just type in 192.168.1.1 or 192.168.1.0 or 192.168.1.254 or 192.168.0.1). Then set it up in there.
