Hi,
I have just set up my own OPNSense server. Everything is working well except for one thing.
I've set up a split DNS system as I'm host my Jellyfin server for some of my relative. The problem is that my mobile phone uses internet banking. The only way I can get it to log in is if i set the DNS on it to use Internet DNS server i.e 8.8.8.8 and bypass my local DNS server. This introduces other issues as I then can't access my local home assistant install using the domain name. I also sometimes access the local Sonarr, Radarr servers by domain name but I'll have to use IP's if I want to use banking as well.
Any ideas what I can do.
Most likely, correct errors in your DNS server.
What is it anyway? What is the relationship of your DNS server to Opnsense? Information is lacking here.
Split DNS as in returning public IP externally and private IP internally?
Not sure how that's relevant.
Is your local DNS not configured to forward request or do recursive resolution itself?
What do you use?
