Hi.
I recently started using Virtualmin in my VPS (a new one) with centos 6.
Unfortunately I've been unable to get BIND to work properly.
If I dig my server I get:
; <<>> DiG 9.9.5-3-Ubuntu <<>> @myserver ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached
But if I connect to it by ssh and do dig @localhost I get:
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> @localhost ; (2 servers found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4628 ;; flags: qr rd ra; QUERY: 1, ANSWER: 13, AUTHORITY: 0, ADDITIONAL: 0

I also checked my firewall and I'm accepting calls on upd port 53: " Accept If protocol is UDP and destination port is 53 "
Can you please help me find the error?
Thank you

Howdy -- it sounds like either a firewall issue, or that BIND isn't listening for or accepting external requests.
It sounds like you looked into the firewall issue, so next you'd want to take a look in /etc/named.conf, and make sure there isn't a "listen-on" directive that's limiting it to just localhost, or that there isn't an "allow-query" preventing access.
Regarding firewalls, you may also want to verify that your ISP doesn't prevent traffic on port 53.
The Support area here is for folks using Virtualmin Pro though -- if you had any followup questions, since you're using Virtualmin GPL, you'd want to open up a new Forum post to discuss those. We monitor the Forums, along with lots of wonderful folks in the community!
When creating a new Forum post, if you're still seeing problems with accessing your DNS server externally, include the contents of your /etc/named.conf file, as well as the output of these two commands:
iptables -L -nnetstat -an | grep :53

I'll open a discussion on the forum.
Thank you for your time.
