hi there pointman,

I'm a newbie on vpn but basically you can implement vpn using hardware or software. vpn can be via gateway-gateway vpn or client to gateway vpn.

Hardware.
- you have a firewall that supports vpn and do vpn gateway. e.g symantec firewall 200R
- you have a router that supports vpn and do vpn gateway. e.g Linksys BEFSX41

Software
- you can use a win2k server box running a RAS (remote access service) as a vpn gateway.

- you can run a linux box as vpn gateway. (Done this personally ssl+pptp+redhat 7.3)
