Need help with IPX

[Wheezle]

Hi. I'm trying to get a game of starcraft running over IPX but i'm unsure if I've set this up correctly. I have pictures of my config windows here

advanced configuration

I've got ports 213 and 214 open and pointed to my computer. The other person is not behind a firewall. We cannot see eachother's games when we go into starcraft though.

Does anyone know what we're doing wrong? The other person's config is the same as mine and our IPX settings are both 802.2 network number 00000

Thanks

Why are you forwarding traffic to yourself? That port 213 is just going to duplicate every single packet by sending a copy to yourself and rebroadcasting it over the local network.

Also, since the alter-source-IP for NAT option does absolutely nothing if you are only interested in tunneling IPX packets, don't even bother with that. You probably wouldn't need it anyway.

But don't I need that? I'm behind a router so I have to direct GIT to my internal IP. It won't accept my external one in the wizard.

[Ark]

Need what? A connection from yourself to yourself in GIT? Or the Alter source IP option? It doesnt seem like you've read any of the various documentation (search forums or read the readme.txt) about that option. It is not required just because you use NAT. It does nothing if you are only using IPX since IPX doesn't even use IP or TCP at all, its not even the same thing.

I mean the IP source. It's just that the wizard for IPX asks me to put in my external IP. But when I do it doesn't accept it because the IP isn't bound to my computer itself as I am behind a router. So I just assumed that would translate my internal IP to the external one.

Regardless, the setup I tried didn't appear to work with that checked or unchecked. Though perhaps it's just starcraft that isn't seeing it... I might try some other game.

The wizard uses the list of IPs to set up the GIT connections, but it removes your own IP from the list (which is why it asks for it above in the single line box)
The wizards that do that are designed so that you can have up to 8 different LANs all connected automatically by entering 8 different IP addresses, and it will create 7 different connections from each of the 8 different GITs, with a unique port number for each of the connections.
When you just have 2 people, it just uses port 213. For 3 LANs it will use 213+214 for the first person in the list after sorting it, and 213+215 for the second, and 214+215 for the 3rd person. It just saves you the trouble of having to enumerate all the combinations when you want to play with multiple LANs.

[Wheezle]

Well if i'm entering my internal IP, should it still work when my friend puts in my external IP? Or is there more to it?

[Ark]

Actually no, if you put your own IP in GIT and you are using UDP, GIT will send the first tunnelable packet from itself to itself and then mark the source address in that packet as remote and stop tunneling anything from that address. So in effect, you make GIT do absolutely nothing but sit there and watch all the packets go by not forwarding anything by having a connection to yourself.

[Wheezle]

sorry I mean entering my internal IP where it asks me to enter my own IP

[Ark]

Are you referring to the wizard scripts here?
Where is says 'What is your external hostname or IP address?'
Or someplace else?

[Wheezle]

Yep, that's what I was referring to.

[Ark]

Nope, you enter your external IP there, which must be routable on the internet and have ports forwarded or opened in the firewall as needed. The only purpose of those two boxes in wizard scripts is to establish the GIT--GIT connections across the internet. It doesn't matter if you are using NAT or playing an IPX game, you must enter the internet routable IP address that other people are using to connect to your GIT with on port 213 or so.

[Wheezle]

Yeah, but that's my problem. I can't enter my external IP there. Since i'm behind a router, the IP is not physically bound to my computer so the wizard won't accept it. It only accepts my internal one.

[Ark]

What do you mean the wizard won't accept it? The wizards are fairly open to accepting most anything usually. You could enter garbage in the boxes and it would accept it.

[Wheezle]

I'd give you the exact message, but at the moment i'm having the winpcap problem where git just gets stuck at starting up. Can't seem to resolve it. I don't see a reg_dword called device either.
