      Hi everyone

      I'm having a problem configuring DNS forwarder and i could really need some help
      I have DHCP service enabled in LAN interface

      LAN DHCP: 192.168.0.40-192.168.0.50
      LAN GW : 192.168.0.1

      So my first machine connected to the LAN and got this configuration

      ip:192.168.0.41
      subnet : 255.255.255.0
      gateway: 192.168.0.1

      I enabled the DNS Forwarder and added a static entry in the configuration, host=test, domain=example.com and applied the changes

      In the windows client , when trying to nslookup the above host i get an answer from the DNS that i use in the WAN interface and not from the Local DNS from pfsense

      C:\Users\user>nslookup test.example.com
      Server:  google-public-dns-a.google.com.
      Address:  8.8.8.8

      *** google-public-dns-a.google.com can't find test.example.com: Non-existent domain

      and of course when trying to ping the host i get

      C:\Users\user>ping test.example.com
      Ping request could not find host test.example.com. Please check the name and try again.

      The strange thing is that when i use the Local DNS i get the correct answer

      C:\Users\user>nslookup test.example.com 192.168.0.1
      Server:  pfSense.example.com
      Address:  192.168.0.1

      Name:    test.example.com
      Address:  192.168.0.41

      What am i missing in my configuration?
      Please feel free to ask for any configuration and i'll post back with settings

        "What am i missing in my configuration?"

        Your client is using google for its dns.. Make sure your client is set to get its dns from dhcp vs hard coded.  Or you have a different dhcp setup that your client its getting its dhcp from.  Simple ipconfig /all will tell you where it got its dhcp from.

          Hi and thanks for the immediate response

          Just before the comment i did an ipconfig /all to make sure of the DNS configuration and for some reason, maybe forgotten from previous troubleshooting, indeed i had static configuration in the IPV4 DNS section, i changed it automatically use the DHCP settings and i can now get the correct response :-)

          Thank you so much, you were right and my problem is solved
