I've just acquired a new hosting box with Ensim 4.0.3-22.fc.2 (Fedora) on it and immediately noticed that port 53 tcp/udp are blocked using iptables which makes having it as a DNS server a little hard

I'm pretty new to this level of linux and especially iptables/rndc and was wondering if someone could outline the best way to proceed - even if that may be not to have this as a DNS server at all?

My plan was to use easyDNS as a secondary name server and open up tcp/udp port 53 for their specific source IP's to allow zone transfers - is this the best way to proceed or should I be looking at employing rndc more effectively?

Very lost Any help much appreciated!

Thanks, CS.
