PFSense + Kloxo, setting up name-servers.
-
Add a portforward ( Firewall: NAT: Port Forward )
WAN TCP/UCP * * 50.xx.xx.51 53 first.internal.address 53WAN TCP/UCP * * 50.xx.xx.52 53 second.internal.address 53let these port forwarding rule add firewall rules.
I put these rules in, and reset all states…
Nothing.External Resolution is not working.

there is something else, because i can use 50-73-183-52-pennsylvania.hfc.comcastbusiness.net as lookup server in nslookup, but i can't make any queries
-
What could it be? I'm lost :'(
-
Can anyone shed some light into setting up an internal DNS server on a CENT OS machine behind Pfsense for external resolution?
I want all incoming dns queries to be handled by a name server behind the firewall.
-
Have you configured the server to accept such requests?
Does the server log any DNS requests?
-
It is a kloxo install with iptables turned off at the moment.
Pfsense is preventing it from being accessed somehow.
-
if you have created portforward rules, which i gave you earlier, then pfsense isn't blocking those.
-
Could it be my virtual ip mapping? What would be the proper settings for my virtual up addresses?
-
I highly doubt that, because i can connect to your dns/bind server, but can't make any queries.

Disabling iptables may not be sufficient; the name server software itself might need to be configured to respond to DNS requests from public IP addresses. (Some SSH server packages need to be configured to specify the IP addresses from which the server is allowed to accept connections.)
Pfsense is preventing it from being accessed somehow.
That might be true. Can you provide evidence? For example, does the pfSense firewall log report blocked DNS requests on the appropriate interface?

When doing a trace route, it times out after hop 14…
Also, my server does not return any records...
How can I fix this?
-
These failures are "easy" to fix:
- Missing MX-record: add mx-record to your mail-server's public ip
- Missing SOA: add Start Of Authority number, which must increased every update
but all of these seems to be dns-server problems. And that's why doesn't mean that pfsense is only quilty.
-
I think I might have fixed it…
For some reason if you check " Non-cached DNS " on that site, it'll show my SOA record.
Weird.
