Hacking a windows process: I have an internet filter; I want to share that filter via the network. But first, what process is it? How does it filter?

Hi, (Hackers only) I want to proxy my internet filter to another machine. It's a pretty complex proxy; it captures browser traffic (probably by process name, i.e. [login to view URL]) and filters the internet. Now, this is great; I want to 'share' this filter to another computer on the network. But when I share the network, it does not pass through the proxy... Here's my setup: Machine A [[login to view URL]]: Windows 8.1 box + Internet filter + proxy Machine B [[login to view URL], Gateway: [login to view URL]]: should access internet via Windows 8.1 machine. RESULT REQUIRED: When browsing the internet on Machine B, the internet should be FILTERED just like it is on Machine A. Currently, Machine B already has Machine A as a gateway, and internet works but the internet is NOT filtered. Need this fixed. Notes: We should use teamviewer or other screen-sharing to solve this.
