A practical guide to VPNs, IPv6, routing domains and IPSEC

Crystal Kolipe writes in about a new article posted by the crew at Exotic Silicon on fun things to do with OpenBSD —

Implementing a self-managed, dual-stacked VPN.

Today we’re showing you how to use iked to tunnel both IPv4 as well as IPv6 to a remote server for a self-managed VPN. We’re doing all this with utilities from the OpenBSD base system so the setup is nice and sleek, completely avoiding the need to install countless programs from ports.

Not only that, but we’ll also show you how to isolate the VPN traffic in it’s own routing domain so it can be used only when required, (or if you’re really clever like us, you can even configure more than one simultaneously).

Of course, the setup supports inbound connections too, so you can run servers from diverse physical locations whilst using the inbound address space and connectivity of the datacentre. Stuck without IPv6 or inbound connectivity at home? Not anymore!
All this excitement and even more is right here waiting for you in setting up an IPv6 capable VPN. Read it today!
