      I'm trying to set up a self-hosted chat server with one of the /29 public IPs we've got from our ISP.

      I have the virtual IP / 1:1 NAT set up on pfsense and the public DNS resolves the welcome page correctly when I try accessing it from outside our network.

      From inside it however I get the pfsense's warning page about the potential DNS rebind attack.

      What's the easiest way to fix this? Changing the pfsense's webconfigurator port?
