I've been looking for a while but I'd like to to implement a vpn solution for anywhere from 1-5 employees at a time (possibly 10 in a year or so)

edit:

Basically I would like outside users to fire up a client or open a web page and be able to access things inside the company network (share drives / printers/ webapps /etc)

I've looked at Astaro Gateway but im not sure if that's the right tool for the job.

I know "best" is a subjective term so i would like to break it into to different suggestions

1) what is the cheapest solution given the criteria above

2) what solution will result in the least amount of headaches from the point of view of maintenance and learning curve.
