I'm running Windows XP on a virtual machine (Orace VirtualBox 4.0.8) on a home server and I want to be able to connect to it from outside the network. I have the domain thanks to dyndns.com which points to the computer and the router is port-forwarded to the server computer. But am I supposed to forward to the server or the virtual machine's IP? Now when I try to connect I get an error: failed to connect.
And how does these authentication methods work: null, external, guest?
