I have been trying to set up a DNS server behind a firewall and I have had less than desirable results. I can successfully operate a Web server behind the firewall, by opening TCP port 80, but the DNS server does not work even when opening port 53 UPD and TCP. I have restarted named and reloaded the configuration after placing the DNS server behind the firewall. My domains do not resolve from other networks (ISP's) when I put the DNS server behind the firewall. I also use this DNS server as the primary for my local network. Is there a change that needs to be made to the named config files? Another port that needs to be opened? Thanks In Advance
