Hello again I have this in my fw roules to allow acces to a nameserver inside my net (it will be moved to a DMZ later).
iptables -A FORWARD $v -i $INTER -o $INTRA -p udp --destination-port domain -d hygglo2.gdpc.se -j ACCEPT (all the used domainame is specifide in /etc/hosts so the fw can go up before the net). It works as far as I can look up names from remote sites. But zone transfere dont seam to work and the dns server crached mysteriusly last night so something migt anoy it :-/ Is there any more ports that needs to be open for a full working dns server? Is ther some kind of cookbook for what ports different services uses? I have got prety far by loking into /etc/services and guessing ;-) but it don't feel all that secure :-/ TIA /Lars
