Question BIND DNS server closed port

simplicio75

New Pleskian
Hello, I'm new in forum and plesk.

I have Ubuntu s.o 14. and plesk 17.

I have tried to create a Authoritative DNS, but I understand the port 53 closed, I opened the firewall, it is as if no service was listening on port. I thought plesk bind9 to launch automatically, in any case I do the manual start successfully [ok]. But the DNS server is not listening, does anyone have a suggestion, thanks a lot
 
Hello,
if i use nmap on localhost port 53 is open service domain
if i use namp on my pubblic IP port 53 is closed (i check from another pc too)

this is my setup on port 53:

sudo ufw allow in on eth0 from any to any port 53 proto tcp

sudo ufw allow in on eth0 from any to any port 53 proto udp
