Hello I am also planning to create a firewall by my own.
And I succeded in configuring a proxy on local machine using c#, but i dont know to configure a proxy on local LAN. and I have to communicate that proxy server with local machine so i can filter based on the user's login.
I dont know how to do by WCF or by Windows application or Web application. could anyone just give me a hint that from where should i start.
