Question BIND DNS server closed port

[simplicio75]

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
