PFsense DNS Rebinding issue
I am running PFsense version 2.0.2-RELEASE (i386) (FreeBSD 8.1-RELEASE-p13). On the domain registration i have forwarded it to point to where the servers are located at. Have got port 80 forwarded on the firewall to the web server. Anytime we try to view any of the hosted sites on the server we get the DNS rebinding error screen.
"Potential DNS Rebind attack detected, see http://en.wikipedia.org/wiki/DNS_rebinding
Try accessing the router by IP address instead of by hostname."
We are trying to view the sites by using their domain names for example domain.tld in firefox and getting that error screen. We want the internal users on the LAN and the external users of the WAN to be able to view the sites without needing to use the internal 192.168.x.x style of work around.
Enable NAT Reflection. You're hitting the pfSense GUI and not your web server(s).
