Title: (Resolved) If I enable Forwarding Mode in Unbound DNS - DNS lookup Fails
Post by: cguilford on February 12, 2020, 04:27:13 pm

OK so I'm running 20.1, and Unbound DNS, if I goto Services/Unbound/General and tick "Enable Forwarding Mode" my DNS lookup fails on my Windows boxes behind opnsense, if I do a lookup from Opnsense itself it works fine.  Anything on the LAN side fails, saying it's not getting a response from the DNS server.  I have DNS setup to 1.1.1.1 and 1.0.0.1 under System/Settings/General.   As soon as I uncheck Enable Forwarding Mode everything starts working again.   Any thoughts as to why this would be happening?  I have a single DNS setup on the Windows boxes and that's the opnsene box itself.

If I look in the Unbound log files I'm seeing alot of this -
unbound: [4579:2] error: duplicate forward zone . ignored

Never Mind, it looks that I was setup with forward-addr: 1.1.1.1@853 forward-addr: 1.0.0.1@853 under Custom Options
