Running a server behind a NAT router (Windows)

[sappie123]

I managed to successfully host an UT3 server behind a router on a windows machine. Ofcourse port forwarding has to be setup correctly.

I found a workaround for the problem that the server is sending the internal ip to the server list. You have to make sure that your external ip address is provided with a DNS name (although supplying an ip address in the regeditor instead of a DNS name might also work). Then you have to change the server's hostname using regedit. Go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters

And change the values of "Hostname" and "NV Hostname" to the DNS name of the external ip address (e.g. myserver.com). (Perhaps either one of those is enough; I didn't test that).

That should do the trick. Have fun!

Next time explain better. I understood most of it but wtf is the "DNS name of the external ip address"?!?

Still, we shouldn't have to do that much messing-around to make out server work. There will be very few people online if Epic isn't inteligent enough to fix this before releasing the game. Usualy for any game, port forwarding is enough to make it work (-_-).

I found a workaround for the problem that the server is sending the internal ip to the server list.

I am looking at what the GameSPy server browser is providing - 400 or so servers, THERE IS NOT A SINGLE ONE using IP address from the private block (internal addresses).

Where do you guys are getting these ideas is a mystery to me.

I am not sure what is the most common problem with UT3 server behind NAT, but trust me, the server is not registering with its internal IP address.

Your router (connected directly to the internet) will be provided with the "external" ip address. That ip address should be bound to a domain name.

Still, we shouldn't have to do that much messing-around to make out server work. There will be very few people online if Epic isn't inteligent enough to fix this before releasing the game. Usualy for any game, port forwarding is enough to make it work (-_-).

I may hope that for the final release this workaround is not neccesary anymore; this workaround is thus for the beta demo only. (that's why we're in the "Beta Demo Feedback" subforum)

Well this does seem to be the most common problem actually (I don't know why you guys are getting the idea that that's not the case ). Check for example here or here ...

When I don't use this workaround the launch.log for the server reads:

I am <hostname> (<Internal ip address>:0)

When i do use it, the log reads:

I am <hostname> (<External ip address>:0)

[devnulll]

What is in the log should be the internal IP address of the server. It the router's job to translate that to the correct one to the outside world.

I think the whole thing started from the sticky about the server installation:

joeGraf Quote:
"browser, but noone seems to be able to connect to it."
That's because your advertising an internal IP address, which is not directly addressable by the outside world. You need to publish the server on an external ip address.

I think the above statement is wrong and I can prove it. The list bellow is the full list with UT3 demo servers at the moment. Would you please show me where are the servers advertising their INTERNAL IP ADDRESS (blocks 192.168.x.x 10.x.x.x and 172.16.x.x link)

400 servers found

[Str1der]

I think the above statement is wrong and I can prove it. The list bellow is the full list with UT3 demo servers at the moment. Would you please show me where are the servers advertising their INTERNAL IP ADDRESS (blocks 192.168.x.x 10.x.x.x and 172.16.x.x )

Maybe the master browser filters private ips from the list?

Riiiight.... and how do you see them in the server browser then - when you try to connect but you can't?

It dosen't matter. Of course this will be fixed in the final release as they have stated.

[devnulll]

Actually what I am trying to prove is that there is nothing to fix. Everything works as it should be, just the router (NAT) device has to be configured properly.

So, do not expect it to be 'fixed' as they can not. There is nothing to fix.

The only thing they can change is to make the UT3 Server Query port static. As you can see from the server list above, it is dynamic at the moment.

[Rhykker]

Sorry for my ignorance, but is this a fix for a listen server or a dedicated server?

Due to my router, people have been unable to connect to my listen server (I properly forwarded port 7777).

I have not tried setting up a dedicated server as of yet, but I was under the impression that people would be able to connect, since the problem seemed to be with listen servers.

Bullsh*t, as I did forward the port just like any other game but ONLY UT2004 and UT3 doesn't work with my Router so the problem isn't me but Epic with their **** that need to be fixed...

Well all I can say if your behind a router you in deep do do. I have tried 3 different routers. I even bought a brand new linksys and it still did not work then I called linksys and was on the phone with them for hour and a half and still did not work. Even setup a static ip still did not work with the ports foward to 7777 both UDP and TCP. Even Turned Off my firewall. Still did not work. So just for SH!TS and GIGGLES I took off the router and guess what IT WORKED!! Now there is no way in hell somebody going to convience me that the router problems are at my end that for **** sure!!!

[devnulll]

OK I will try it myself - most likely Monday. I have one Linksys router and will see what is so hard about getting it work with UT3.

[L'enculeur]

Ya there's just no f*cking way to run a server behind a NAT, no matter what you try to do. Since so many person have a router and also don't want to pay for a dedicated server, it would be a shame if Epic release the game with this thing not fixed.

I did it yesterday!! I was sure i had the solution... Afther i played co-op with a m8 for like 3 hours.. he had to reboot..after that, he could still just connect! I was not sure what did it..but what we did: We both installed the beta-patch. I opened all ports, but i still got the error that i couldnt host (new feature from the patch), so I (the host) enabled DMZ and i hosted a game as a LAN!!! game.. My m8 also forwarded 7777, while he wasnt a host.. Then he could join @ the console!!!

But now, a day later.. it wont work anymore.. we didnt change anything!! I hope you guys can do something with this info... Because we dont hear anything from Epic :S:S
