Recently trying to set up an opnsense router and properly use VLANs. I have a DMZ VLAN set up for future proofing but don’t have anything actually on it. I currently have my PiHole on the LAN, and was wondering if it is safe to create a firewall rule allowing DMZ devices access to the PiHole on port 53 for DNS services. Thanks!
