one last thing about BIND -

if I ipchains block it...

ipchains -A input -i (external interface) -s 0.0.0.0/0 -p TCP 53 -j DENY -l
ipchains -A input -i (external interface) -s 0.0.0.0/0 -p UDP 53 -j DENY -l

does it seem to safely stop BIND attacks so I can use BIND on this machine
to supply DNS to the computers on the internal network?
