P2P and remote port 53

[Meltdown]

Grateful for any help with interpreting my firewall log below. It looks as though some peers connected to emule and utorrent are using port 53 on their computers: is that correct? It seems odd.

Not surprising,I have seen email ports like 25 and 110 in use for P2P to bypass ISP blocking of traditional P2P ports.

I've also had the same experience with people using ports 53 and 110 to connect to my system while using bitorrent and e-mule. Seems to be coming something of the norm, i wouldn't worry to much about it.

Okay, thanks people.
