OpenVPN

I've been looking at OpenVPN recently with a view to giving it a try. I've used FreeSWAN previously, and it's a nightmare to configure and setup, requiring patches applied to the code, kernel rebuilds and so on; and you get even more "issues" when you need to use NAT Traversal. A quick look on the OpenVPN site linked to this article at Fedora News, which in my case is fairly relevant as I tend towards the Redhat distributions. It all certainly looks interesting as a good and free alternative to IPSec based VPNs.
