Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-mobile@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I was wondering if there was currently support for Mobile IP in either FreeBSD-regular or FreeBSD-PAO? (i.e., tunnel-style forwarding/encapsulating of IP from the home network to the mobile location). I am in the process of writing a user-land IP tunnel utility for use in a VPN-environment, but as the behavior of Mobile IP is very similar, it seems applicable. I currently have an implementation of a tunnel using /dev/tun over UDP, but will have a raw-sockets direct IP encapsulation (using IP protocol 4) sometime later this week. This is something that could definitely be done kernel-side, but since FreeBSD does have a nice user-land tunnel device, this seemed like a quick way to prototype it.
