I will start off with saying that I am not a 100% expert in networking or security.
I have a customer who is a long way from us. Their network admisn have provided us a public ip address such as email@example.com. So using "firstname.lastname@example.org" , we log on to the customers server using Remote descktop, over INTERNET - broadband. we have access to the server as administrators and can run terminal sessions.
the server has lots of client pcs. I installed VNC( free version) on all clients and the sever as well. I wanted to get access to any Client PC using VNC, so
I have the client running the VNC server - lets call the client pc "client1", ( and it is also set to start up on windows start). When I try to connect to the "Client1" usign VNC viewer on the Server (email@example.com), it just waits and says that it cannot connect "unable to connect to host - connection timed out". HOWEVER,
I can connect the same way if I am physically in the LAN ( at the customers site I mean).
I use the free version of the VNC . Only that I did not try "Tight VNC" ( i am not sure of the diffrence ). I tried with ip address, with the VNC Viewer listern running with no luck.
how can I configure VNC please ?
