When I try to play the OP dyna on my other computer, I get an error message saying firewall has been detected or I'm not online. I turned off the firewall on that machine and the host, and I am connected to the internet on the other machine, so what's the deal? I can access the dyna from the host machine just fine.

Network specs:
2 machines, dial-up internet connection (avg speed around 40kbps), connected through a simple 5-port ethernet hub

That is the message I tend to get whenever I have the ports forwarded to one machine, but try to play on the other. (whoops!) Are you doing any port forwarding? Any port triggering?

I'm not sure from your post, but if you are trying to get onto the dynaverse with both machines at the same time, I don't think that is possible.

I don't know how to do anything with the ports, and I HAVE gotten them both on once before. If the ports have changed themselvs, could ya tell me how to change them so my set-up will work again?

Might not be the ports, but the IP you are forwarding them for. If you are using DHCP the IP of the local machines can change on you.

Well Max, dunno if this will help.... But i was having the same problems myself. I would try and log on and it said that my computer was behind a firewall and I needed to change my settings or that the firewall server was down. The only change in my system had been that my brother had been visiting and i had him hooked up to my computer via another network card so he could share my Cable connection through my computer. It worked fine Before, During, but not after. Only changes i had made were to diable that card which also turned off the connection sharing that was going. When i tried to log on later that day after work, I got the messages you were talking about. I tried everything i knew to do (aside from calling my brother over to hook up his computer) but to no avail. So, sad as though it may seem, I did somethign else for a while, there was this strange box in my living room called a "TV" that i watched for a while. That was a fortunate turn of events as i found out that there was a war or something going on. Then i ate dinner, a very nice New York steak if i recall. (Unlike Vulcans, Romulans are NOT vegetarians) SO, before going to bed i tried to log on D2 and did so successfully. Everything worked fine (except the chat) and was as it was before. This led me to the assumtion that it was something on the D2 server end since i don't run a firewall on my system.

I deny of course that I have no firewall, because no Romulan would leave his system unprotected......

What brand router do you have? If it is Linksys, you should be able to log onto a web page at (I think) 192.168.1.1 (or it could be 198.162.1.1 -- I can never remember)and adjust your ports there via the handy GUI. You can pull the ports you need from your EAW manual, and check which machine you need to forward them to via your DHCP table.

EDIT: Translation:
Your machines on a router (usually) share a common IP address with the outside world, but have a unique internal address. If you use the GUI to look at your DCHP table, you should see that each of your machines has been assigned a unique internal address like:
Machine1 = 192.168.1.100
Machine2 = 192.168.1.101
This will be the unique address you will need to forward your relevant ports to so that your hub knows which machine to pass the packets from the server to. Check your router manual for details. HEY! Someone who actually knows what they are talking about get in here and explain this better.

If your router is another brand, I'm going to prove clueless I'm afraid. Sorry I can't join you on a chat, but I'm nowhere near an MSN capable machine right now.

Did you really get both machines playing on the D2 simultaneously? Or only playing one another via LAN? Kudos to you if you did. As the game would have been using the same ports for both machines, I'd have thought it would get confused as to which machine should be receiving which packets from the internet. But I'm just a layman at network stuff. It would be cool if I could get both my machines hooked up to a dynaverse at the same time.

More info is needed on your network layout (topology).

It sounds like you have one PC with dial-up modem that connects to the internet, and that PC also has a network card which is connected to a simple hub (not a router), which in turn connects to your second PC. And you are probably using ICS or Internet Connection Sharing, configured by a windows wizard.

If this is correct then we need to know what the OS's (operating systems eg Win98) are.

ok, Cleaven (you're the closest to what I described I have), both machines are running XP

is that all the info you needed?

Isn't a Router the guy who comes and unclogs your toilets and cleans your sewer line?

naah, that's a 'rooter'

like in 'Roto Rooter'

Right then, what is required here is experience with ICS under XP, which I haven't used (only tried it with 98SE and it didn't work). I understand that it is much more configurable and actually works as it's meant to. Anyhow, dive into the help on ICS and look up how to open ports up to the 2nd PC on your little LAN.
To play SFC2 you need the following ports:

2300-2400 for TCP & UDP; and
47624 for TCP.

If you want to use GSA there are a few other ports required but get the D2 working first.

Yes, the host machine is fulfilling the role of router, in a similar way to a "real" firewall setup that somebody might configure using a linux box, for example. You need the host to be configured to let the PC's behind it communicate with the outside leg of the network.
