Open DNS port from pfsense

  • Hello Guys,

    I have a server in my LAN and port 53 is open in local but when I test this port from pfsense GUI diagnostic/Test Port and I get "Connection failed". I have ping and all the other ports like 80 are open too, does anyone have idea what is the problem and how to resolve it?!!!

    Does it answer on tcp?

    That tool doesn't test UDP. Says so right on the top of it..

    Is the device directly connect to your lan or is it downstream?  So I have dhcp on a lan side vlan of my pfsense - using the tool to test 53, reports back fine since the dns is also listening on 53 tcp for full dns.

    When you say open - do you mean on the hosts firewall.  Since there is no rules required on pfsense to talk to lan devices - unless you put in some outbound rules on your floating rules?
