Playing StarCraft as 2 people on the same network

I am currently renting a house from a person who has two houses on his property. Both of us play StarCraft, and we like to play together. We're using the same router, and the upload / download speed is more than high enough for two people to be playing StarCraft. When we play separate games of StarCraft, it works.
However, when we attempt to play 2vs2 or UMS, the game lags a lot and sometimes people will drop.

We have edited our registries so that our StarCraft clients use different ports, and opened those ports for the correct computer. This hasn't fixed the problem.

I've searched for answers for a long time, and although I remember fixing this problem while visiting this guy in the past, I haven't found or discovered a solution. I don't know anything about networking; I have a book on SDL_Net that I plan to read at some point and that's about it.

Does any one knowledgeable have any ideas?

Are you playing on iccup or Remastered? On remastered or the official bnet it shouldn’t be a problem ever since the “new” battle.net.
Sorry, my post is rather not helpful really.

i would rly try battle.net tech support forum for this, but i remember it was horrible always to play from internet cafe and playing together was basicly impossible ... but that was from 2001-2004 so how much that is the same problem i aint know

Only thing i can think of, your ISP assigns same public IP (after NAT) for you both. Maybe SCR provides connection for each private IP if you are in separate games (so you get 2), but only 1 connection for each public IP if you are in the same game (so you get 1 despite having 2 private IPs). In this case you could ask your ISP for different public IPs, not sure if it's doable.
In any case, post this on Bnet forum as well, developers know best how their network works.

We have the same IP adress, btw.
I'll look into ordering another IP

One simple solution is to have one of your computer connected to VPN. If you dont have VPN you can download Tunnelbear for free and use it for the first 500Mb (remember to turn it off when you dont play).

One of you can connect your phone to the computer and tether the internet instead of using normal internet.

BW uses minimal data, so it's not a problem, and mobile internet latency is ok.

The solution here may be helpful.
http://www.icyhell.net/starcraft-on-b-net-with-2-computers/

It essentially does what you already tried, but with different subnetmasks for each computer and some custom iptables rules that resolve the issue. A router running openwrt or dd-wrt can do this, I don't know about commercial firmwares.

I can confirm this works but it's a hassle. Next time I would rather setup VPN or connect one comp through mobile phone...
