hi everyone

i know it's not a modding issue directly, but testing, bugfixing, troubleshooting and finally playing your maps and mods with your friends - that's gonna demand an option of running an own private server

here are the datas:

- vanilla coduo 1.51, without any mods
- a basic server.cfg in the uo folder
- a shortcut to coduomp.exe, with settings like this: "E:\Games\Call of Duty\CoDUOMP.exe" +set dedicated 2 +exec server.cfg +map_rotate
(- i even tried some kind of fixed exes for starting up a server, but nothing happened)
- comodo internet security firewall, with the particular exe files set as trusted
- linksys wrt54gl router with "block anonymus requests" disabled, and the following port ranges forwarded for my internal ip: 20500-20510, 20600-20610, 27900, 28900-28970 both udp and tcp
(router firewall is obviously enabled, and it it should remain this way, because the internets would punish me if i sacrifice the security for a server, so i hope there are other options to think about. i also cannot setup a static ip, net supply works only with DHCP set dynamic ip)

if i run this server via the shortcut mentioned above, a console/command line appears, and according to the messages, the server is up and running. when i add my external ip to the favourites in All-Seeing-Eye, and refresh, it does find the server, and i can join, i can be ingame, but in the console i can see that i am recognized by my internal ip (like 192.168.etc), and that's suspicious.

then i pass my external ip to my friends, like /connect 79.12.13.14:28960, and ask them to join the server this way, they stuck in "Awainting connection... 8... 9...", and it could go till the end of time, instead of awaiting gamestate after 3 waves as normal. if i ask them to do the same without the port at the end of the ip, the same thing happens.

so my questions are:
- is it possible to run a private/public/whatever server behind a router that folks knowing my ip can join?
- if it is, what did i do wrong? what can i try?

thanks in advance

it is possible to run a home server
but it really isn't worth the trouble
the main thing is that you need to find out what your upload speed is
it doesn't matter what your download speed is as most internet providers give you a big download speed but the upload speed will be basic (as most people download and not many people upload and if they do it isn't much)
you need the upload speed so your server can send information to the clients to tell them whats going on in the server
it will be fine up to about 4 players then the pings will go sky high and game play will suffer A LOT (laggy as hell)
also if you want to test maps and mods you will need a redirect to download them from a ftp or website
a lot of the free websites wont host pk3 files

@ozzy: thank you for your reaction, mate. i believe that my upload bandwidth is fair enough for 4-6 players, it's 512 kbytes/sec, should be enough. the custom pk3 download should not be a problem, i can take care of it.
what i can't seem to take care of, is that making this server eventually accessible outside my home lan network, possibly because some workaround needed with the router, and that's why i'm interested in other experiences and knowledge about this. thank you

You need to have UDP port 28960 forwarded to your PCs LAN IP, which can be done somewhere in your router settings, then other players should be able to connect and your server should show up on the server browser.

thanks for the reaction mate, as i mentioned above, i have forwarded 28900-28970 both udp and tcp which i believe pretty much covers this

Oops, forgot you said that part when I was replying >.<


You say comodo firewall is allowing the exe, but is Windows firewall disabled? If not then you need to allow it on that too.



That's because of NAT redirection, the router sees that you are connecting to your external IP from within the LAN, so it keeps it all in the LAN.

You can also try running a program called Wireshark and see if your computer is receiving packets from your friends when they try to connect.

Iv'e never understood why peeps would want a home run cod server (apart from the cash side) the problems it causes is a nightmare and never knowing when your game will be ruined by many issues.
You can buy a fantastic 10 man server with redirect for £3 a month from alpha networks.
Your own fully controlled redirect for £2 a month from gaming redirect.
Anyone can run there own cod clan with Server / Redirect / Voice server / Filezila / website and forum for just £3 a month and if there is 6 of you that's 50p a month.
If details are needed by anyone let me know.

thanks for the reply. of course i'm aware of this solution, there are providers in my homecountry, too, with similar financial conditions and good ping. however, i have a reason why i won't chose this, it's not financial, however, it has nothing to do with the original idea of this tread. thanks for mentioning it anyways

I have previously run a coduo server from home, years ago. Connection was 512k both up and down, and worked ok for 10 players, although we mostly had about half that.

Only the LAN address would show up for users on the LAN, users at other locations would see the correct external IP.

I'll see if I can dig up my old notes, may still have them.

Big drawback was ping - those on the LAN around zero ping, external users around 100. I live in a regional city, and I think other players, even though living locally, their signals had to bounce to the state capital and back.
