Hi. I like to host multiplayer games such as Counter-Strike online for my friends to play. However I have a problem finding out my port number for the game. I can find out my external IP using websites or whatever.
My current setup is this: a PC connected using wire to a modem, which then connects through the telephone line to my ISP. I got ADSL and I'm staying in Thailand. I'm not sure if it's my modem's or ISP's fault...
Anyways, I already forwarded the right port (27015 for cs I believe, but it is the same everytime). So in theory my game's IP should be [external IP]:27015, right? However when I ask my friends to search for the server, which is currently the only way of finding it, they tell me the IP, and everytime it is a different port.
So my question is if there is a program or website available that could for example check my external ports and report which are open, or check if there is a cs game running on any port.
Also note that the function which searches an IP for any running games in Steam's add favorites tool can't find my game when I give my friends my external IP. Also I've posted this question about a year ago on the Steam forums but they haven't answered. I figured you people should know a solution.
Thanks.

search google for TCPDUMP, it outputs a lot of information but you can narrow it down nicely with restrictions and outputs to logs.

I can't figure out how to use it. Is there any other method?

I dont really know a simpler method, ummm there shouldnt be a problem with you hosting at all if you only have the cable modem in the way and no router splitting the signal after it comes out of the cable modem.......well you could start the CSS server and print the results of a netstat -n

So in theory I should get an IP with port 27015 when I got dedicated server running right? Using the PID (netstat -n -o) I've identified steam going over port 3289 and there's an unidentified process over 4030, could any of those be it? Note: all ports are from the local address column... should i use foreign address?

it will be in the local side, any port you have open

OK. Thanks a lot. I will try next time we play a game and ask them.
