I have setup Truenas scale 22.12.2 on my network and used Truecharts to install some apps. Inside the LAN I access the the apps through Traeffik and local FQDN’s without exposing ports. No problem with that. My problem starts when I want to access the apps remotely through OpenVPN. I use pfsense 2.6.0 with the openvpn set there. On the openVPN server I have enabled the Local DNS option, I created an access list on the DNS Resolver, but the addresses cannot be resolved. Any ideas on what should I do more in order to have access to the apps?
Do you have a different DNS server on the network or just the Pfsense firewall as DNS? It works when I point my client back to my internal DNS servers. But this was also a site to site VPN that I was using.
