I am trying to figure out how to work Warcraft 3 online gaming with my LAN.
Both computers on the LAN can get online and play games but when one
computer hosts a game, another computer on the LAN cannot join it. I thought
I saw something about how to get that to work somewhere but I can't find it.
:-\ So if you have any idea how to get this to work, please let me know.

What kind of setup do you have for your LAN?

All computers are connected through 2 Linksys routers to a VPN and then to
the system with a NAT firewall thing which is connected to the cable modem.
the firewall can't be turned off so you can forget that idea right now. :-P

The problem is probably the routers. Do they support loopback?

Well, here's the big big question. Does the LAN work with any other
multiplayer TCI/IP game?

I can join games by opening ports in the firewall, but we've never been able
to join a game we are hosting.

Some game servers do not allow multiple gamers to log on from a single
public IP address.
Some games do not allow multiple log ons to the same game which were
installed from the same game disc.

It may be possible to create a static IP for each of the network PCs and
forward the ports used by the game to the IP address of the game server.
You would need to know the default client ports for that particular game.
for hints, see page 58 of your linksys manual.

Have you tried connecting through a single router? Your system seems
unnecessary complex, which may be causing a conflict somehow.

Heh, We would love to have one router but we have... er... I think 12
computers connected and I have yet to find a router that I can buy that will
hold that many connections. They're all for commercial use.

We have 2 games for Warcraft 3 because we know that it will only allow one
logged in user per serial number. We can connect at the same time and join
games, but I cannot join a game that is hosted by a computer on my network.
However, we have no problem with both of us joining a game not being hosted
on our network. I think the computer just has issues when it tries to send
the information and finds out it's sending the information directly to
itself (the gateway computer). Now if it had a way of knowing that the
information is being sent directly to itself and instead took it and routed
it to the other computer that's hosting it, it would act as a network game
but it'd be online so the host computer should be able to send out my
information to all the other computers on the connection as well. The
information from the host computer should be sent fine because as far as it
knows, 192.168.0.3 is the IP of the player and the gateway computer would
simply route it through the LAN.

So I guess what my question is how to I configure my NAT program to do that.
If you're wondering, I use NAT32 (http://www.nat32.com) as the NAT program
on the gateway computer. Incase you're wondering, it's running on a Win98
machine and I can't change to a different program. My Dad wouldn't let me.
:-P

Wow, now I know why I dispise routers so very much. The way I do it is
simpler and doesn't hurt my head as much :). I'll post how I do it :

I think a simple fix for this would be to take one of your 12 computers and
set it up as a direct connection to the internet. Make sure this computer
has 2 network cards (one for the internet and one for the LAN). Get a hub
(I've seen one that supports 24 computers so that's no problem) and plug
this computer into port 1.

Now connect each of your computers to a different slot into the hub. If you
run out of room on your hub, you can either put another network card into
that one "gateway" computer (so it has 3) or try to connect the two hubs
together via the uplink port (that's in most hubs).

Now, you have to get Internet Connection Sharing to work on that gateway
computer, After you tell it which network card has the connection to the
internet and which one shares it with the LAN, it should be just running a
setup file it tells you to make on a disk for all those other computers.

If all goes well your connection should work, just as it did before. I'm
not saying yours is a bad setup but I know this works (it's hard to get
working at first though). To get it working, simply open ports up via ICS
configuration program :
http://practicallynetworked.com/sharing/ics/icsconfiguration.htm.

That's all for now :)

err... that is how it is. LOL. Everything connects to a hub and.. damn, the
routers come in the equation somewhere. I needa go downstairs and look at
that again. I know we have 2 routers, a big huge hub that we had to splice
the wires to connect to it and then it all connects to one computer (the
gateway) that gets online and uses ICS to get the rest of them on. And a VPN
comes in there someplace, too. LOL

But anyway, somehow I don't think that would solve my problem. :-P

Ok, I suggest you completely remove the routers from the equation. Replace
them with a couple hubs and have the gateway give out the IP's. Instead of
going with the router VPN garbage. :P

I'm not sure but by looking at this documentation
(http://www.nat32.com/htm/route.htm), I think that this command should route
all information that would normally try to be sent to itself to my brother's
computer (he would be hosting). I'm not sure if this routing will work for
outgoing information. It might be that it only works for incoming
information that would be used to route it to certain computers in the
network.

route add 66.189.28.129 192.168 192.168.0.101 0 0

Well, we definately need the VPN. My Dad's work would automatically ban our
IP if we tried to connect without one. LOL :-p

Here's the whole scoop on how it's connected.

All the computer ethernet ports are connected into a phone connection in the
room which all come down in the basement. Those phone wires in the basement
are spliced and connected to this big plastic thing which is connected a
bunch of spliced ethernet cables which then connect to 2 Linksys hubs. One
of those hubs connects to the other hub and that hub connects to the VPN and
the gateway computer. There's another ethernet connected to the gateway
computer but I can't remember where it connects to... probably the second
hub.

Sorry there, I mixed up the hubs and routers. :-P We ain't got any routers.

[View Quote] Well that's simply solved. Log onto the gateway and use VPN to connect
whenever he needs to. No need to muck up your LAN just to make sure all the
computers can connect.

Wow all I'm going to say is that's messed up.

Aug 13, 2002, 4:42pm

Shush you, it's the king of low-cost networking with a buncha computers. :-P
It works well.

And causes a lot of problems down the road!

Aug 13, 2002, 4:46pm

Not yet. I don't think how this works is causing the problems this topic
started with. :-P I just needa figure out how to route outgoing shit.

um read the faq on blizzard it said lan isnt supported...

pfft, just cause it's not supported doesn't mean it can't be done.
