OpenVPN? SSH does support tunneling, but OpenVPN is nice and automagic. I'm sure it's lightweight enough to run on the N800, has likely been ported, and can be scripted to connect upon finding a 'net connection (or daemonized to always attempt). I know there are some in the Atlanta Asterisk Users Group that use OpenVPN for SIP around NAT (because SIP sucks on NAT - even with stun).
Sounds like a cool 'lil project! Good luck! On Mon, Nov 16, 2009 at 11:06 PM, Dave Manginelli <[email protected]> wrote: > OK.
