FQDN aliases are not resolved



  • Hi mates,
    I have some aliases used in my firewall rules that contains both IPs and FQDN.
    If I try to connect to a destination defined as FQDN in the aliases I cannot connect, while I can ping it.
    I use internal DNS, not the PFSense resolvers...
    If I look at the firewall log and investigate by resolving the IP it is correctly resolved.
    What's wrong?
    Thanks a lot



  • Show some examples of what you mean and how it fails.

    Lets see your rules as well.

    And if your clients are using internal DNS.. What is pfsense using for dns - if the fqdn listed in your alias resolve differently by client vs what pfsense resolves, then yeah you could have problems with those aliases in your rules.



  • After some investigation the problem is relative to 2.4.4 p1.
    Once I roll back to 2.4.4 everything works fine.

    I use the same DNS both for clients and Pfsense (Windows 2016 domain controllers with DNS)
    The IP resolved are the same for each DNS query..

    Well lets see this problem you say p1 has.. Other than it doesn't work some times..
