UDP Port problems

(1/1)

mibtech:
Hello,

I am looking for some assistance with troubleshooting an issue with udp ports not appearing to open.

I am running a game server on a vmware windows 2003 server the port it requires is 2302 udp.

netstat info from windows 2003   UDP [fe80::5efe:192.168.1.11%2]:2302      *:*
                                                UDP [fe80::ffff:ffff:fffd%4]                           *:*

I have created a nat rule that has also created the firewall rule


I have also tried many port checkers and none shows the port open.

The game server is visible and usable on the LAN but not visible on the Internet.

I have also gone through the troubleshooting guide but I could not find anything in the guide that would solve this problem.

Any troubleshooting steps to try next are appreciated.

Use Diagnostics - Packet Capture to sniff your WAN and LAN to see how that traffic is entering the system and what happens to it.  I suspect that the game requires more than just 2302/udp.  If the game you're running is Freelancer (FLServ) then you need 2302-2304/udp, not just 2302/udp.

you are correct the main udp port it requires is 2302 but many sites recommend 2300:2400 so I have changed it.

Lan to the ip packet capture

17:25:32.966835 IP (tos 0x0, ttl 128, id 31987, offset 0, flags [none], proto UDP (17), length 44)
    192.168.1.11.4114 > 5.9.69.107.2300: [udp sum ok] UDP, length 16


when I try Wan to the ip the packet capture is empty

This game can't tell you exactly what it needs, and you have to go by what gaming sites think it needs????  You're never going to get this right if you don't know what's required and have to guess.  Go to their main site and check their Support section for network details such as exactly which ports you need to forward.

Then you're doing something wrong.  You should be seeing udp traffic destined for your WAN IP.

I have gone straight to the manual on the disc I have the correct ports.
