Are you running a p2p fileshare client? This kind of traffic is typical with filesharing, as your machine is trying to talk to other filesharing machines, and those other machines are off-line. Your machine getting back an ICMP port unreachable is the Internet way of saying “we’re not filesharing right now”. Since CFP is blocking the inbound ICMP, your fileshare application doesn’t know the remote machine is off-line, and so keeps trying, and you get an ICMP message back for each time it tries. The solution is to put in a rule to allow inbound ICMP port unreachable traffic, so your fileshare program will get the out-of-service message from the remote machine.
