My daily log is full of messages like:
8/25/12 8:27:01.385 PM Firewall: Stealth Mode connection attempt to UDP 192.168.1.101:40959 from 18.104.22.168:1098
where 192.168.1.101 is IP of my mac. Port 40959 is constant all over messages and "from" addresses vary as well as its port.
I am getting few of those messages every minute. Should I worry about it?
