VPN securing internet traffic;

[ub3rz4ch]

Firstly sorry if this is in the wrong section :P

My question is as when it comes to networking I am a complete NOOB (only reason I have managed to set up pfsense is help of tutorials haha), How could I encrypt all my internet traffic LAN and WAN (like a transparent proxy/vpn) without actually using an external VPN or some other dudes VPN service (dont know if I can trust people providing the VPN).

So using pfsense I can connect to a VPN easily but can I make the VPN local in the same network but make all traffic go through that first? I dont know if this makes any sense, but I basically wish to find a way to encrypt all my internet traffic without the use of a external VPN

Thanks :)
