looking for a software than identify an intruder process

My firewall advise me of an intruder since a week.
I've seen this:

"
IP origin: my IP (not static)
IP destination: 203.122.204.132.
Origin Port UDP: 10222.
Destination Port UDP 0. Not valid number
"

Does it exists a software which identify the process generating this traffic(possibly free) ?
What can I do?

seems perfect!

Whois is always free. They are in Australia. Don't worry about it.
