DNS Search Domain

« on: March 30, 2024, 01:36:10 am »

Hello all,

In System/Settings/General there is an option called DNS Search Domain. I recently have stood up new infrastructure, including firewalls. I have to swing my public domain name over to the new infrastructure. Can I use DNS Search Option to add the public domain to each device that sits behind the firewall?

Thanks,
Steve

The one in System>Settings>General is only for OPNsense itself.
We can use DHCP to advertise Domain search list to network clients.

HTH.

That would be great...if I was using DHCP. Maybe Unbound has something.

Not in the sense you probably want. Usually, it is uo to the client to provide a search domain. You can either set this via DHCP or specify it manually if you have static configurations.

Unbound will not help you with that, but dnsmasq can by providing a default domain if the client sends none.
