I was checking my firewall log just a few minutes ago, and saw a slightly suspicous series of entries. First there were 8 individual connection attempts from the same IP to UDP ports 33493 to 33488, then a single portscan entry from the same IP for UDP 33493 to 33488 again. I tried searching for common trojan ports because I couldnt find the port numbers in my rfc printout. Is there any reason to be concerned about this, or is it possibly just someone randomly scanning IPs?
