Multiplayer Problems » Forum Post by overkill1991

Try opening port 6000 too. It sounds like there's a firewall issue going on. Are you running anti-virus, Norton Security, Windows Defender, etc? Those could be blocking the game.

Definately firewall. I had this same problem a while back with the beta, what I had to do was allow my brothers ip access to my pc.

Thanks for these fast replies guys !

I'll try to open port 6000 too Yarlen. I'll post back here if it works

Oh and no I'm not running any of the programs you listed.

Unfortunately we still can't play together.

I've opened ports 6000 and 6112.

I get the same message each time I try to connect to my friends server ''disconnected from the game server''.

When I try to host a server he can't see my server for some reason :/

It's very strange because I can host servers just fine on all the other games I have.

I hope someone is able to help me with this problem!

Are you by any chance at a university? They may block those ports regardless of your router settings.

No I'm not at a University.

If nothing else, you can always use Hamachi to create a workable LAN (yes if you are already on your own LAN it seems rather silly but hey desperate times, desperate measures!). You can get it over at Hamachi.CC

Basically, just download it on both computers and install it. Create a network on one and name it something. Then on the other one choose "Join Network" and type that in plus whatever password you set. Once you are both visible to each other in Hamachi (should have green dots next to your computer names in the list) you can go into Sins and create a LAN game as usual. The other computer should now see it just fine.

I use Hamachi all the time to play LAN games across the internet with my friends, but it should work on local LAN games just fine as well. It basically creates a VPN - virtual private network, which gets around firewall and port blocking issues.

Forgot to include an actual link for ya, here is one to download Hamachi: WWW Link

I tried Hamachi but I run into the same problems :/

How many connections are shown in the windows network connections folder? If your machine has more than just the LAN configured there, that might cause issues as well.

I'm not entirely sure I understand what you mean because I have the Dutch version of windows so all the things have different names.

I think I found what you were refering to, I can see 4 connection things in there. My internet connection (LAN), Wireless connection, Netword card and also one for Hamachi.

I have no idea how this can cause any problems or how I could possibly fix this.

Try disabling all connections except the LAN one. What he means is that Sins might be trying to grab the wrong connection (for instance your wireless one) and is therefore not seeing your friend on the LAN. Just right-click and choose "disable" to turn off all of them except the LAN connection.

Thanks for all the replies guys. I solved the problem now, It had something to do with network adapters

If you have the means (understand what I'm explaining) you can verify some things this way:

1. fire up Sins, start a MP game, then Alt+Tab out of the game
2. open a command prompt (Start > Run > type "cmd" (without the quotes) > press
3. then issue the command "netstat -abn" (no quotes) and verify the output

[Do not post the output as it may have sensitive info in it]

What you'll want to look for is any references to Sins LISTENING on the appropriate IP/port(s).

Once you verified this is correct you can have someone (you trust) nmap your public IP and verify they can "see" the IP/port(s) open as well. This MUST be done from outside your internal network obviously. It's a pain and you need to know what you're doing, but this will determine for sure where the problem lies.

Yeah I finally did some multiplayer myself and got the notice that others wouldn't be able to join. Alt+tabbed out and threw up a Battle.Net service enabled on my router and it worked like a champ even though it still complained that the ports weren't open. I think you have to restart Sins to have it recognize the change in the network states but it still works fine. Got a 3 hour start to what should be a 10-hour multiplayer game or so

Forgot to specify the nmap command in my last post. The app is available HERE.

There are several options that will give you the info necessary to determine whether or not your machine is accessible from the outside world for specific ports:

prompt> nmap -v [-sT|-sS|-sA|-sW] -p 6000,6112 x.x.x.x

-v <=== means "verbosity level", spits out even MORE results in the command window
[-sT|-sS] <=== these are differing scan techniques you can use, only pick one though
-p 6000,6112 <=== the ports to check for, TCP in this case
x.x.x.x <=== this is the public IP address of the hosting PC/Server

EX: nmap -v -sW -p 6000,6112 10.10.10.1

You're looking for the result to say "open". If you see "closed" or "filtered" (firewall/router issue most likely still), then there is an issue you'll need to figure out.

Me and my friend have the same problem, could you write a bit about how you solved the problem because I have no idea how to do it.
- Thanks

Same here, I have the same problem, down to the fact that I can see his games but he can't see mine.

For hosting a game, your best bet is follow the advice given here by The Monk:

http://www.kiclan.com/monk/Networking_and_SINS_by_the_Monk.pdf

More details are here, but basically you need to forward TCP ports 6000 and 6112 to your hosting PC's IP address.
