In my firewall log I see thousands of udp packets from ip addresses all 
over the word trying to access my freebsd gateway server on port 53.
Right now I am blocking them and see no negative effects.
Is there any valid reason to allow these unsolicited inbound packets 
access to my system on port 53?
