Quick advise: Racoon and IPsec

[Anders Breindahl <skrewz@skrewz.dk>]

Hello list,

I am going to be fiddling with some ipsec'ing for securing my WLAN and 
enabling tunnelling to my home network through the Internet.
I had great success last time I asked d-u for such quick advise, so I'll try 
again:

Can you please provide your preferred points of entry to the field of 
tunnelling and automatic keying?
Is IPsec and Racoon what I want? Which alternatives exist?
Are there any common sources of error in this field, that I should be aware 
of?
Anything else worth mentioning?

I should mention, that I have tried the IPsec HOWTO by Ralf Spenneberg, but it 
didn't answer all my questions. Great short introduction, though.

Regards,
Anders Breindahl/skrewz.
