Sorry, but that guide is bullshit. 90% of the steps are unnecessary or even plain dangerous, and it doesn't fix the fact that 1:1 port mapping won't occur.

I haven't investigated it in much detail, but it would seem that simply setting the Game Data Port in HKEY_CURRENT_USER\Software\Battle.net\Configuration to a unique port per user and setting up the appropriate port forwards would be the correct fix.


It fixed my issues. I can now play with more than one other person, which I haven't been able to do for quite some time.

It would be nice, but I know from my own trial and error that 6112 (default) is all b.net uses and completely ignores the edited registry values

As I said I didn't test much, but I went onto bnet and confirmed my registry key value was the port opened by Starcraft. I assumed beyond that it would work.

sorry to bump again but, i recently bought SC because my cousin convinced me to play again but i'm having this same "cant play with more than 2 people including myself or else i'll lag" the only thing is i dont have a router? i just have a modem (embarq dsl) and i'm on windows vista. im direcly connected to my modem or w/e. what do you guys think the problem is? so much for my excitement to play again..

(im not a very technical savvy person)

the guy that wrote this thread really can play in a network without lagg? i said, i fixed after 2 years my problem of lagg (now i can create games anf the people can join), but i never fixed the lagg when 2 pcs of my network join the same game.. its impossible!! only some routers can make it...

oh men, i just want to be wrong about it.

I played around with this, got it working with 2+ people, the problem is NAT. If you have a router behind a modem, newer modems act as a router, and SC hates double NAT. So you have to turn your router into bridge mode. I had to patch my router to a custom firmware to do this though.

2 or more behind the same router is possible, a friend of mine did it but I don't remember what he did.

how do i access my modem (which you say is a router too?) so that i can change these NAT options? i just have one computer, with one modem for my DSL connection.

damn i wish i could fix this by tonight but looking at past problems from other people... i doubt it'll happen.

It might be caused by portforwarding/firewalls in your case. (Can you host games?)
Um, if you have windows go to start - > run and type cmd . This should bring up a black dos screen, type ipconfig and press enter. Find the octet string of numbers by Default Gateway, then go type that into your internet browser bar. It'll ask for name/password, this is usually admin / admin .

That's how you get into your router, as to how you change all these settings, it's very, very different for each router.

no i can't host games, people trying to join get the lat error. oh and yea, i've been to this before, but i just don't know what to do. i turned off my firewall on my computer and on my modem/router through this settings page to no avail.

there are some other forums i've found with my problem and they solve it with making a static ip address or port forwarding, but somewhere in the steps is something that they have but i don't and i end up running into a wall (like one had me inputting the info from ipconfig into something like the properties of my network, but for him he had multiple dns servers(?) but i only had one, and the change wouldn't accept two repeated dns servers, so i was stuck).

the weird thing is, when i played before i didn't have this problem. the problem seems familiar to me, but i don't even remember fixing it or how (last time i played was like 2 years ago). in other words, if i got it to work before there should be something i'm missing. heh, this is killin me.

btw Nevuk, or anyone else that thinks they might know the problem, if you need any screen pics of parts of my modems web page or w/e, just let me know. i can't even watch a replay with more than one person, how sad is that.

thanks in advance to anyone.

Hmm, can you post what modem you have?

http://portforward.com/ is the most commonly given site for people with your problem. The issue is definitely portforwarding as to why you can't host games - the router prevents devices from outside the network being able to send specific things without permission, and with port forwarding it allows a specific service through to reach your computer (in SC's case, it uses the UDP port 6112). If you can post a screenshot of your router page I might be able to help more.

i'm using embarq DSL, and my modem is an embarq 660 series.

here's a picture of the port forwarding page on my modem's page, it's in the NAT section. would this be the place to put 6112 as a start and end port? what ip address would i use?

Yep, this is where you put 6112.
To find out your IP, click start -> run
Type ipconfig and hit enter.
The number to the right of 'IP Address' is what you want to enter in the IP field.

You'll want to type cmd, then type ipconfig in the dos window on most computers (ipconfig insta-exits otherwise). But yeah, this is exactly right.

yup, i got the ip address from the run -> ipconfig process. put 6112 in the start, and 6112 in the end, and for the ip address i put the one i got. still no luck. =/
