Background & snazzy picture:
I provide internet to my Mother 4 blocks away via wireless bridge. She's unable to afford her own internet service (to disabled to work) and my younger brother an sister rely on internet for school an of course their social lives. I have this approved by the ISP. honest. I used to work for them and my wife still does.
I think my picture is pretty straight forward as far as the details pertaining to my questions.

Task:
I have a PC with pfsense installed and I would like to use it to perform additional content filtering for my mothers home. I need to install it at my home, not hers.
My network "edges" on the Router/wifi RB951 at my mothers house.
WAN is on my LAN, and then NAT and DHCP for devices in her house.
Im using OpenDNS already but I want more control over the content. They are still managing to make a mess...
