Hi all,

I have been experimenting with freesco http://www.freesco.org (FREE ciSCO)
router distro as a replacement for Linux Router Project. I have a DNS Server
setup behind the firewall servicing port 53 requests.

I have Freesco and running and all is well except for DNS.  I have a DNS
server behind it and I have ports 53 udp and tcp passed through to it.  I
keep getting these errors:

My question is what causes these?  Is it a hack attempt?
