out of curiosity i tried following what skype does when connecting and chatting. i found that the port 24953 and port 35840 is always connecting to many different computers. sometimes during a chat, i get more than a few packets per second on this port. all the packets are being dropped by my firewall, but I can still talk normally with others. Why is my computer and others trying to use that port# when it is always being blocked?
During an actual chat or call, the port skype uses is also different than those two ports. So, what are those ports used for? does skype use them? or does someone on my contact list have spyware/malware?
