Interesting. I'm getting hits on UDP port 13151, but I can't remember how to tell what process is listening.

Although the log is showing hits for IPv4, netstat shows the following:

$ netstat -an | grep 13151

tcp6 0 0 :::13151 :::* LISTEN

udp6 0 0 :::13151 :::*

Several web searches are giving no indication of what is using udp 13151, nor do I know why it's getting through my home NAT to reach my system on IPv4 at all.

IPv6 has no NAT, but I still put together a "stateful firewall" on it, as an exercise in paranoia, and that log isn't showing the messages that v4 is.

Ok, found it...

# netstat -tulpn | grep 13151

Turns out it's Azureus, I'm serving several Debian disk images.

Interesting, though, that the port only shows listening for IPv6, but it's coming in on IPv4....
