Maybe this question is stupid but i have to post... I am completely new in Free BSD world but every day when i use Free BSD i realise that i have some questions about network that i didn't think about before. One of them is encryption... How is secure of data which sent to the global network using some of the many "chat" ways (MSN, Facebook, Gmail) or password... I have pf but is there a possibility to put that network connections to tunnel and encrypt it? How to do that or some instructions... Thanks
