Hi there --- Once I've got the normal stuff in place on a test standalone box [default drop, accept related + established on tcp, loopback enabled] iptables -A OUTPUT -p udp -s $LOCALIP -d $DNS1 --dport 53 -j ACCEPT Shouldn't this be enough to allow standard dns resolution to take place? According to Ziegler, it should? Or am I a complete plum. Any pointers as to my plumness gratefully received. Thanks :) steve ----------------------------------------------------------------------- Information in this email may be privileged, confidential and is intended exclusively for the addressee.
