I am looking to configure TheGreenBow VPN client (installed on his laptop) for a user that travels form one client site to another client site and he is using has his laptop (XP SP*) .

Would the user be able to connect to his office via VPN from any of those clients sites ( they have broadband connection) if he used his laptop ?

As you know I am not allowed to touch clients’ routers to configure necessary port forwarding for to the user’s laptop
