server 2003 dns and a firewall was created by octavius
hi to all!
if i have a server 2003 and a firewall, should i need to open the port 53 for the dns root hints of the server 2003 to operate? i have iptables on my linux firewall.
any help will be appreciated very much.

Hello and welcome 
Yes, the machine on which the DNS server is run must be able to connect to UDP* port 53 of the hosts mentioned in root hints. Unless of course you only operate an authorative servers (in which case you don't serve foreign domains at all).
*theoretically TCP as well, however it is so rare that an answer will be so large that TCP will be used, you can ignore it
