ping LAN device by hostname with domain name vs without

[imthenachoman]

I have a brand new pfSense box. I converted my TP-Link Archer C7 AC1750 to a dumb AP / switch that is plugged into the pfSense box. Everything works so far.

At first I could not ping LAN devices by their hostname. I made some changes and now I can ping by hostname but not by hostname.domain. I am not able to figure out why.

Change I made / My settings:

• System / General Setup
  • System
    • Hostname = sense
    • Domain = lan
  • DNS Server Settings
    • DNS Servers = 1.1.1.1 and 1.0.0.1
    • DNS Server Override = unchecked (I don't want my ISP to set DNS servers)
    • Disable DNS Forwarder = unchecked
• Services / DHCP Server / LAN
  • Domain search list = lan
• Services / DNS Resolver / General Settings
  • Listen Port = 53
  • Enable SSL/TLS Service = unchecked
  • SSL/TLS Listen Port = 853
  • Network Interfaces = ALL
  • Outgoing Network Interfaces = ALL
  • System Domain Local Zone Type = Transparent
  • DNSSEC = unchecked
  • DNS Query Forwarding = both checked
  • DHCP Registration = checked
  • Static DHCP = checked

Now I get a response if I do ping server but not if I do ping server.lan.
