Here is the scenario.
I work for a company that offsources employees from the Philippines to do the a large amount of our graphics work. Initially they need to be trained and to do so we have been using RealVNC to connect to their desktop over Cisco VPN client connection between us and them. To this point they have all been working at home with seperate DSL connections, but now we have hired three that live together and would like to share one DSL connection using a router (likely a Netgear WGR614). How can we continue to utilize the VNC if they are sitting behind a firewall sharing the connection? Is this possible? Typically the router will assign an IP to each PC (192.168.x.x) which is useless to use when we attempt to connect. We are sitting behind a firewall as well, but we only need to be able to control their PCs, not vice-versa. Ideas? Do I need to supply more info?
