I am attempting to set up a standalone DNS server for external resolution.
What ports need to be opened on the firewall for DNS queries to be received
and served?
TIA

53 TCP and UDP.
 
Thanks so much - I'm having trouble getting this server to respond to
requests - is there a white paper setup someplace that I could reference?

TIA
