"Quote from: disorganise on April 12, 2026, 02:45:09 PMFirst confusion: I don't know what DNS servers it is using, but it doesn't appear to be anything I set.
As far as I understand, I'm using Dnsmasq and Unbound, though I don't really understand the relationship between the two.
Is Unbound enabled in Services => Unbound DNS => General => Enable Unbound?
If so then Services => Unbound DNS => Query Forwarding should tell you what upstream DNS servers it's using, and whether these are the system DNS servers from System => Settings => General or not.
If Unbound isn't enabled then you're probably using Dnsmasq. Is Services => Dnsmasq DNS and DHCP => General => "Do not forward to system defined DNS servers" selected? If it is, it should be using the servers from System => Settings => General, or if not the servers from Services => Dnsmasq DNS and DHCP => Domains.
Do the log files for Unbound or Dnsmasq show any errors?
On the windows host, when getting its IP Configuration automatically from DHCP, what does "ipconfig /all" in a command prompt show? Has it picked up its DNS configuration from your OPNsense? Also it might be worth using "nslookup" to check DNS from the command line as browsers can sometimes try using their own DNS over HTTPS configuration.
Quote2nd confusion:Probably better to stick to one problem at at time for now :) Well worth trying to work out how your DNS is currently configured before getting the sites to query each other. Your plan for a forward from one site to the other sounds right though.
