I beleive this is the second article about VPN, the first one and also tihs one were very great and helpfull, thanks a lot, I just wanted to know if I have three overseas locations, all are connected to the Internet, what exactly do i have to do to have VPN fully functioning under windows2000! like 3 routers, 3 leased lines, 3 W2k advanced server ... what else do i need in terms of hardware or software? do i have to install a firewall on the 3 locations, or is it just an extra option, i hope wecan have some discussion about this case...
