This document will explain howto set up an IPSec encrypted GRE tunnel on OpenBSD. In the document, both end points are OpenBSD 4.1 systems, however it should be fairly straight forward to implement on other systems.
To start, I would advise disabling pf on gre0 and enc0 until you have the encrypted tunnel working, this […]

This paper reviews the process to configure racoon/ipsec-tools to authenticate IPSec communications via x509 certificates.
Our example does not cover howto configure a Certificate Authority (CA). This process will be examined in another paper. Our example also assumes the clients are both NetBSD, however the procedures are nearly the same for Linux, FreeBSD and […]
