Hi,

Can anybody tell me what this traffic is?

I've been altering on our router's access list and I noticed this in the syslog. 
Access list 120 is on one of 2 ethernet interfaces and is inbound to the router from 
our internal net. Both machines run DNS, 1.2.3.4 does transfers to our provider and 
1.3.3.4 is a primary DNS for our internal net. As you can see these happen about every 
second and the port number increments on the sender, 1.2.3.4 every time.
