I have been reading the forums and user guides from youtube and google, but there is some things that a evading my brain.

Current setup

Modem (wan) (Goal is to eliminate this and just use pfsense and have it directly hook to the ONT (optical network terminal))

pfsense (lan)
    /
Switch > (wireless Access Point) > Netbook, Alienware, iphone, ipod, hp tablet,

I have been doing a lot of reading, one of the things i was wanting to do was setup a squid.

I set some firewall rules to block all "http/https" communication and have it redirected through the proxy server.

After a few hours on trying to get it to work, I realized that I had to use the port "3128".

Presto magic "we have internet"

After some more reading, i discovered wpad.dat file, and i gather with this implemented there will be no need for manual settings.

Last evening i used pfsense.org tutorials and used this as a reference for my network.
I tested the script manually in the browswer and got it working.

http://doc.pfsense.org/index.php/WPAD_Autoconfigure_for_Squid

My first problem.

1. How do upload or place this script in the proper directory / directories to get this working properly (for all devices that connect to the network)

2. How do unblock certain sites.

3. How do i allow all other traffic through such as my netflix.

My final goal

I would appreciate some direction or help in the matter.
