(this works on NT, 2000 and XP)

Go to a command prompt and do a "netstat". You will see a list of results like this.

Code:
Active Connections

  Proto  Local Address          Foreign Address        State
  TCP    yourhost:3152      irc.dal.net:6666       ESTABLISHED
  TCP    yourhost:3977      xx.92.244.xx:ftp      FIN_WAIT_2
  TCP    yourhost:3978      xx.92.244.xx:ftp      TIME_WAIT
  TCP    yourhost:3985      xx.92.244.xx:ftp      ESTABLISHED
  TCP    yourhost:3987      xx.92.244.xx:ftp      ESTABLISHED
  TCP    yourhost:3996      forums.mirc.com:http  CLOSE_WAIT


On the left side where you see the numbers after "yourhost" this is the port your client is using for the connection. The port on the right column shows THEIR port, and has NOTHING to do with the limits in YOUR client.
