I have one ubuntu netbook (8.04 hardy) and one ubuntu desktop (10.04) and I would like access my home computers desktop with my laptop. I can do this when I am at home in my own network, but I cannot do this outside of my own network. I have set up my router to forward the port (5900) to my computer and I have set www.dyndns.com account (forward's to my routers ip address) that I use to try to connect outside my local network. I get a "connection to host was closed". Any help would be great. Thanks!
