Have a look at some of the Open Source VPN software. 

The Linux FreeS/WAN implementation of IPsec has all its docs online at
www.freeswan.org. I'm a tad biased, since I wrote them, but I think they
should have most of what you need, and I hope they're understanable :-).

See openbsd.org, freebsd.org, netbsd.org and kame.net for other Open
Source IPsec. PoPToP is an Open Source PPTP client. vpnc.org (VPN
Consortiun) has a lot of info as well.
