So I've had this working for some time now, but wanted to announce it to the group. in case anyone wants to try.
I have a VPN router on vpn.w9cr.net You can use an IP sec VPN dialer to connect to it and then get an IP out of a /28 I have set aside for it. I don't mesh with the 44net ipip encap, but I believe we have connectivity to that via the hamwan guys from Seattle.
I have no radius server or anything fancy, it's a crisco 1811 in my rack in tampa. I've confirmed it works with the apple VPN dialer. carrar has it working under windows with shrewsoft too.
If you want to test/play send me your callsign/name and a password (numbers/letters/uppercase, no special char's), and I'll provision it and send back the group ID and PSK.
