We configured the tunnel server to listen on tcp/222. This first screen shot is of netstat -ano, then filter for 222. the -o switch gives the process id, so the next command filters for that process ID (2120). The last line shows PID 2120 is listening on UDP 52079.
here's netstat -bano, but only the applicable portion - KiwiTSS.exe is the .exe identified.
...and further down the screen, here's the UDP port again.
Thanks for your reply.
