Here are some easy point for those who like to research.

My brother and I would like to play Diablo 2 over the Internet NOT using Battle.net. We haven't tried this yet but I thought I'd seek some potential advice. I know we can connect via IP address so that's no problem. However, we both connect via cable modems and have firewalls set up. Does D2 use specific ports for access and if so, what ports do we open up?

Thanks!

We have the same problem...
We tried ip connecting from isdn 2 cable modem, but that didn`t work.
Then we tried from cable modem 2 isdn, and it worked fine.

Good luck

We both have cable modems with firewalls in place. We just need to know if there need to be any ports open and if so, which ones.

Thanks!

okie doke i found the port info for ya:


Hosting/Playing a TCP/IP game (not on Battle.net):

In your Proxy/Firewall software, be sure port 4000 is open to send and receive TCP packets.

Hosting/Playing a game on Battle.net:

You must open port 6112 through port 6119, and 4000 to recieve inbound and outbound TCP and UDP packets in your Proxy/Firewall software.

Although players behind a proxy server or IP-sharing software can join Open Battle.net and Open Internet TCP/IP games, when such players create games, others may not be able to join them. If this problem presents itself, then players using a proxy server should request that another player creates the game.

The reason for this problem involves the difference between external (internet) IP address, and internal (LAN) IP address. Because proxy users do not have an external IP address, they cannot have a direct link to other players who do have an external address. The host of an Open Battle.net or Open TCP/IP game must have a direct link to each player in the game - therefore, players will not be able to connect to a game created by a proxy user.

Blizzard doesn't specifically support proxy servers. If you really want to host a game on your server computer, then you can disable the proxy temporarily. That'll let you host a game that can be joined by people from across the internet (and Diablo should display your external IP address), but such a game probably can't be joined by others on the your LAN (since the LAN computers, now cut off from their proxy, can only see internal IP addresses).

One last note: although proxy users will have trouble hosting internet games from behind a proxy server, they won't have any trouble joining an internet game. If proxy users want to play a game with some people on their LAN, as well as some people across the internet, then one of the players across the internet should host; preferably someone with a lot of RAM.


dont accept this answer till you have tried it and it works!!!  feel free to reject the answer if it doesn't work or if you have more questions

thanks

Hey cool...thanks!
I'll check it out but it may be a while. My brother still needs to get his copy of the game. When he's got that up and running, we'll do the firewall stuff.

STILL haven't heard and my e-mails are being bounced back (not a good sign). I haven't forgotten this and as soon as I can talk to him, I'll see what's going on. If we can TEST it, I'll know.  :-)

Thanks for the patience.

Okay. My brother's back online but we haven't tried the solution. Regardless, the information looks good enough to eat (and comes from Blizzard directly) so I think it warrants an affirmative response.

Here's the points plus a few extra for the patience.  :-)

Thanks for the effort!
