Dear List,

I would like to try tunneling IP packets over an encrypted link (that is,
I would like the tunneling system do the encryption for me).  I will need
to tunnel a subnet from one location to another, but right now I'd like
to test how things work using a wireless LAN as the tunnel and route my
local subnet (or one IP of it) through the tunnel.

There seem to be several devices for tunneling in NetBSD 1.5.  Which one
do I want to use?  tun, gre, ipip, gif, what? :-)

Please help me to get started.

Thanks,

  -jm
