I want to set up a VPN server on my lan. My ultimate goal is to be able to connect Sedna, my MacOSX laptop, using the BUILTIN vpn tech (meaning L2TP/IPsec or PPTP), to my lan, JUST as if she was on the internal wifi connection. I want her to have a tunneled internal IP and act just as if she were local in every respect.
I have a Gentoo Linux system that I would be happy to have running VPN services. I also have the NetBSD gateway box, which I'd be happy to have running the VPN services. Attempts to figure out, from the really poor documentation I've found, how to get this /working/ have all failed. I've taken to pricing out hardware VPN solutions. The problem is that most of them do a lot more than I need (they've got builtin hubs and various other 'features', which are great for those people who want one box that does everything, but which are completely useless to me), and they're not free. While I have no concern with paying the $100-$200 I've seen for items that look like they'd meet my needs, I'd still much rather go with the software solution on one of the two available servers.
SO. Has anybody set up L2TP/IPsec (or even PPTP, tho I'd prefer the former) on either Linux or NetBSD, successfully, for a 'roadwarrior' (as they seem to predominantly call it) setup, who'd be willing to send me directions and/or config files that will Just Work?
