I bought the book and that helped a lot. But there is definitely some  
magic involved.

Man ipsec.conf returns a ton of information about what each  
configuration directive does, but not much about how they interact.

The real hard part, for me anyway, is that when something doesn't work  
it's not at all clear why. I suppose if you're a dyed in the wool  
ipsec fanatic it's all obvious. But for someone who focuses on other  
things, it's can be rough going sometimes to get this stuff working.

But when it does work, it's great!
