DNS fedora box showing P2P activity port 45179 to port 6346

["Jim Christiansen" <christiansen_j@xxxxxxxxxxx>]

Hello,  My ISP provider has reported back to me that they have logged 
suspicious traffic on my DNS box.  Here is a clip that shows what they have 
recorded...

If I lock down all but udp 53 with iptables will my DNS still work??

What the heck is this?? Thanks for any ideas.. Jim
