I have a Zywall 2 VPN router that connects my internal network to the internet. I do not have a server, just 12 w/s. The w/s login to a remote application server which is connected by a VPN tunnel. The tunnel is router to router.
My problem is that 4 users want to connect to the remote server from their houses as well. I have thought of allocating certain w/s in the network to be connected from the houses using Remote desktop or tight VNC. However I can only open one 3389 or 5900 port and foward to one workstation.
How can I access more than one computer through the router?
