Capabilities of IPsec for enhancing online security?

[Curley_Boy 0]

I know that IPsec allows you to filter ports on a machine, but I know it also allows you to encrypt network traffic. Does this capability extend only to machines on a LAN or corporate network, or does this feature allow you to encypt internet traffic?

 

If so is there a good online guide to get me started somewhere and what effect will this have on networking with other PC's on the local LAN that *Don't* support IPsec encryption (XP Home, NT4 etc).

 

I am running Windows 2000 Pro SP4, and am connected to the internet via an hardware adsl router.

Thanks for that, I will try and remember to tune in.

 

But do you have anything I could look at in the meantime?
