How to find info on GRE/IPsec

Hi All,

I have a hard time finding any information how to setup tunnels in
Linux using GRE and/or IPsec. Google is not my friend here... The
problem is that I don't have the background and overview to even start
playing with it. I compiled support for GRE in the kernel, now what?

What I want to do is to build a VPN (a virtual LAN) using those tools.

Any pointer to a book or text or any idea how to learn to do this is
much appreciated.

Regards,
Daniel
