Some DNS problems



  • Ok before I get started, I will readily admit im not an expert by any means but I am always willing to learn.  I installed PFSense as an experiment to pick up some new skills and i've gotten nearly everything working except for a few DNS problems.

    I think the root of my problems is in my Domain setup in the main page.  Domain and Hostname really confuse me in the way it works.  I understand in Windows, that the hostname is basically what its called, something easy to identify the computer with.  I simply put 'firewall' into it.  However, I have no idea what to put into domain.  I don't own any domains nor do I have a windows domain setup.  So I just put 'firewall.com' into it to get past setup.

    What further confuses me is that whenever I ping another host using its Microsoft "computer name", e.g. examplehost, it pings as "computername.firewall.com".

    So that leads me to my 2 problems.

    1.  Remote Desktop doesn't work by computer name anymore, I have to use the IP addresses.  However, mapped drives and ping still works (as described above)

    2.  I am trying to setup some settings in DNS forwader.  I have the following checked:

    Register DHCP leases in DNS forwarder - (I think this is causing the ".firewall.com" extension on the hostname, I initially enabled it because I thought it would fix my Remote Desktop Problem)

    Register DHCP static mappings in DNS forwarder - I have some static IP's set, so I also enabled this.

    So for example here is what im trying to setup.  What a LAN client types "router", they are taken to 192.168.0.1.  I leave the "hostname" part blank (I'm honestly not sure what to put in there) and type "router" into domain and 192.168.0.1 into IP address.

    I set all the others up in a similar fashion but no matter what I type, it always takes me back to my original domain, (firewall.com)

    If there's anything I need to clear up, please let me know.  In the end, im pretty sure it has something to do with my initial domain settings.  Thanks in advance!



  • As hostname you could use firewall or pfsense.
    As domain you should use local or lan when you don't own a domain.
    Tick all 3 under services -> dns and then you can ping firewall.local or pfsense.lan

    Ahh ok thanks, I got the Remote Desktop and the other mappings understood now.

    Just wondering, is there any way to go by either hostnames or domains, rather than both?  For example 'media' instead of 'mediacenter.local but without having to make it media.com.  And also for connecting to computers using ping and RDP.



  • If you get an IP per DHCP your client will have the same DNS suffix.
    Usually if you try to ping just the first part withing the same "subdomain" it will work.

    ie: psymia.mine.nu is my domain.
    a server is called whitemage –> whitemage.psymia.mine.nu
    a client is called redmage --> redmage.psymia.mine.nu
    Now if i ping on redmage "whitemage" it will work.

    Alternatively you could enter your own names in the DNS-forwarder.

    Ah ok, thanks, before it wasn't working by only hostname but now it works.

    Now im off to learn about all these different VPN terms so I can try to setup a VPN next!  :o
