      @johnpoz I have attached some of the setting you asked about. I feel like there is something telling about the response from the lookup. I would not know right now what it means but its not right. my brain might be too far gone to mush. I have tried so many things trying to get this to work i probably screwed this up further. As for disabling anything in unbound, i am unsure how i would have done that as i cannot find any menus for that at all. the Vlans are ran through a brocade switch. beyond that there is nothing seperating them from PFsense. so its PFsense/Brocade/Vlan. I guess if any of this triggers anything for you let me know. Or if you want more information i am all ears. Seems like i am in for a bad day but only on the vlans. DI=is works on the regular lan.

        @sentein Also, restart DNS Resolver after you add the VLAN interface(s).

        Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
        When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

          @sentein that server is pointing to itself for dns 127.0.0.1, where is it actually trying to go?

          Do a directed query.. with nslookup change using server to like 8.8.8.8 then try your query

          $ nslookup                                   
          Default Server:  sg4860.home.arpa            
          Address:  192.168.9.253                      
                                                       
          > server 8.8.8.8                             
          Default Server:  dns.google                  
          Address:  8.8.8.8                            
                                                       
          > www.google.com                             
          Server:  dns.google                          
          Address:  8.8.8.8                            
                                                       
          Non-authoritative answer:                    
          Name:    www.google.com                      
          Addresses:  2607:f8b0:4009:81a::2004         
                    142.250.190.132                    
                                                       
          

          Does that work? Ok set it your pfsense IP.. I take it that is that 10.10.4.4 address?

            @johnpoz sorry for the delay. the wife wanted to go out to eat. Thank you for the help with this. I ran the test you mentioned. When specifying the server the nslookup actually worked.

            I am figuring this means my actual problem is in the server itself. Please correct me if i am incorrect. If thats the case i guess i need to go root around in the setting for the server.

              @sentein so yeah linux will point to itself like that, and then forward elsewhere - but where it actually forwards to you have no idea where, which isn't working what flavor of linux are you running? prob using netplan would be my guess. Not really a fan..

              For example this version of ubuntu is doing it.

              user@UC:~$ nslookup
              > www.google.com
              Server:         127.0.0.53
              Address:        127.0.0.53#53
              
              Non-authoritative answer:
              Name:   www.google.com
              Address: 172.217.0.164
              >
              

              prob want to make sure its listening on 53..

              user@UC:~$ netstat -anl | grep :53
              tcp        0      0 127.0.0.53:53           0.0.0.0:*               LISTEN     
              udp        0      0 127.0.0.53:53           0.0.0.0:*                       
              

              And you can see where its pointing

              user@UC:~$ resolvectl status
              Global
                     Protocols: -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported

                      DNS Domain: home.arpa
              user@UC:~$

                @johnpoz Right now this server is running linux mint 21.3 edge. I tried ubuntu headless but i could not wrap my head around netplan. ubuntu wanted to route everything through the 10Gbe because it was faster. That was not working because the 10Gbe interface was and still is completely isolated. I did try to figure out what is going on with the DNS on the server. Below is the command and the output. It seems that my DNS settings are being forwaded to the server. I am a bit lost as to what it is doing. If you are sure that my problem is in the OS i can go bother someone else. At that point it is not a pfsense problem.

                nmcli dev show |grep DNS
                IP4.DNS[1]: 0.0.0.0
                IP4.DNS[2]: 9.9.9.9
                IP4.DNS[3]: 149.112.112.112
                IP4.DNS[4]: 84.200.70.40
                IP4.DNS[5]: 84.200.69.80

                    @sentein said in Vlans will not DNS resolve:

                    DNS Servers: 10.10.5.4

                    And what IP is that, you should be pointing to pfsense lan IP..

                      @johnpoz that is the DHCP server for the vlan in question. 10.10.4.4 is the LAN DHCP server. So i should requires it to point to the LAN PFsense IP? Maybe thats most of my issue.

                        @sentein does this dhcp server provide dns?

                        Doesn't seem to - do a directed query to it..

                          @johnpoz I thought it was supposed to. Maybe i have something wrong.... I have a second PC for the PFsense box. Should i just start over?

                              @sentein Huh? So you have dhcp running on pfsense.. Thought you said you had a different dhcp server?

                              Also Unless you put unbound into forwarding mode, setting those dns servers is pointless..
