I have a situation where a user has a computer that they only have a private IP address for (ISP assigned). My computer is at work and also has a private IP address.
Using TeamViewer, I can access the remote computer's desktop.
My question is: is there an open source program that can accomplish the same thing? I suspect that TeamViewer works because it has a server that can be contacted and, I assume, set up a tunnel or whatever it does. I don't have such a server with a public IP address.
This is something that I only do occasionally. So I don't want to buy a bunch of TeamViewer licenses if I do not need to.
Any ideas?
Maybe... wild idea. Get an IPv6 address (via tunnel broker? is that the name?), which is public, and access that one instead.
I have told the client to get a public IP address. He is in Portugal. Seems a complicated thing. Or so he thinks. Maybe he is asking for the wrong thing. He is connecting via a 4G wireless thing.
When this client can arrange a port forwarding from the NAT server he is behind, he will be reachable as if he has a public address. The port can be any port number and when he restricts access to his system via this port to only the public address you want access from (yours) in his firewall, nobody else can have access to his system. -- fr.gr. member openSUSE Freek de Kruijf
