DNS Rebind attack with HAProxy

[erichium]

I've run out of ideas trying to get custom DNS entries to work locally. I want plex.home.arpa to navigate to my self-hosted server at 192.168.1.11:32400, but I get the DNS Rebind attack pfSense page. I don't want to worry about any of the certs/SSL stuff for now.

What I've done.

I've tried disabling DNS Rebinding Checks to (via System / Advanced / Admin Access checking Disable DNS Rebinding Checks), but that just navigates to 192.168.1.1 (pfSense admin page).

What am I doing wrong?
