Of course, what you're talking about is a secure access from outside, not a vpn, which
would make your outside machine appear as an insider, with full IP connectivity. That
said, it's trivial to do, at least, if this "Instant Internet" box is flexible.
All you need to do is to redirect an outside port to the vnc port of the system you
want her to have access to on the inside. Then, she just connects to your NAT box,
which actually connects her to her desktop.
If the vnc server is running on a unix system, You could even configure a user on that
box whose .forward file had a pipe to a program to parse incoming mail. Then, she
would send it mail with the correct string, it would execute a vncconnect to connect
back to her listening vncviewer, at the address given in the mail. That would remove
the necessity of port redirection.

Subject: VNC as a VPN ?
Classification:
Have been trying (in vane) for the last couple weeks to configure
VNC to work as a VPN to my internal LAN.
My LAN is behind an Instant Internet 400 box (NAT device).
I can vnc all over INSIDE the LAN, but am unable to access the LAN
devices from outside the II-box because of the NAT mappings.
I have users on all sorts of OS (Win95/98/2k/ME, Linux-RH/Mdk/SuSE) and
accessing
the net through all sorts of methods (ISDN, Dialup 56k, DSL, Cable etc...)
Primarily the users need to access their own onsite workstations (which in
turn
would access the servers).
I need to implement a solution ASAP, as one of my users is about to
head out on maternity leave and needs remote access now.
I am also researching VPN hardware solutions from WatchGuard and Cisco,
but they are pretty spendy.
Anyone ever made this configuration work? And if so, how?
