    Hi all,

    I'm sure there is a simple solution to my question, but I don't really know where to look.

    All I want to do is if I am on my LAN (or VPN), when I type https://hostname,/ I want it to translate it to hostname.example.com for ALL hostnames not defined in the Host Override section of DNS Resolver.

    Current General DNS Resolver Options
    Enable DNS resolver = yes
    Listen Port = default (53)
    Enable SSL/TLS Server = no
    SSL/TLS Certificate = Let's Encrypt cert
    SSL/TLS Listen Port = 853
    Network Interfaces = All
    Outgoing Network Interfaces = All
    System Domain Local Zone Type = Transparent
    DNSSEC = no
    Python Module = no
    DNS Query Forwarding = Yes,
    - Use SSL/TLS for outgoing DNS = yes
    DHCP Registration = no
    Static DHCP = yes
    OpenVPN Clients = yes
    Custom options =
    "server:
    private-domain: "plex.direct"

    Host Overrides =
    Several entries that look something like:
    Host = a
    Parent domain of host = example.com
    IP to return = 192.168.1.x

    Some Host Overrides include alias(es)

      That is on the client side, simple search suffix for example.com

      Now when your host does query for hosta it will really do query for hosta.example.com

      example..

      My host.

      indows IP Configuration                          
                                                       
        Host Name . . . . . . . . . . . . : I5-Win     
        Primary Dns Suffix  . . . . . . . : local.lan  
        Node Type . . . . . . . . . . . . : Broadcast  
        IP Routing Enabled. . . . . . . . : No         
        WINS Proxy Enabled. . . . . . . . : No         
        DNS Suffix Search List. . . . . . : local.lan  
      

      See the search suffix - now when it pings it for say some host it auto does query for the fqdn including the domain

      $ ping brother
      
      Pinging brother.local.lan [192.168.2.50] with 32 bytes of data:
      Reply from 192.168.2.50: bytes=32 time=1ms TTL=254
      Reply from 192.168.2.50: bytes=32 time=1ms TTL=254
      

      You can see my client did a query for the fully qualified name
