Squid reverse proxy

[bboy8012]

I am having a hard time getting squid reverse proxy working. I followed this http://www.moh10ly.com/blog/pfsense#Installing%20Squid3%20for%20reverse%20proxy%20(HTTP%20only), but when I disable my Nat port forward it redirects me to my pfsense management page and says potential dns rebind attack. I am new to reverse proxying and trying to understand it and set it up for my 2 webservers. Thanks
