RTP streaming/tunneling over Internet

[Tim Wood]

Hi

I use openvpn for this type of scenario.  You may find as time goes on 
there are other things 'at home' that you want access to while you are 
remote.  Mac support for openvpn can be handled with e.g. tunnelblick as 
a nice simple wrapper for the connections.  In your setup that might mean

- install openvpn server on "Server"

- forward a port [ to be used for vpn] from nat router -> "Server"

- install openvpn client on 'Client PC'

If your home IP is not static, that is a separate fun problem to solve 
but there's a few ways around that

Cheers

Tim
