When setting up a DNS forwarder for a VPN tunnel between two IPFire installation, see e.g. IPsec, DNS answers from the remote IPFire will be dropped, because no validated answers are provided.

May 28, 2013 · For quite a long time, I have been using pfSense as a router/firewall/gateway for regulation of traffic between the LAN and WAN side. PF was configured with some simple rules (mostly NAT-rules), and the software was set up with "DNS forwarding" (dnsmasq) with a static IP on the WAN side and definition of the ISP's name servers.

DNS over TLS, for example, forces your pfSense firewall (unbound resolver) to encrypt the DNS transaction as it traverses the internet; what that means is a man-in-the-middle on the internet (or a nosy upstream network provider) can’t see which hostnames you are querying and as important, no pfSense manages two physically separate networks, but accessing the server with the domain brings up the "Potential DNS Rebind attack detected" warning page when accessed from either network, however, using the IP address brings up the server's pages just fine.
