I have been using RealVNC for years so feel pretty familiar with it, however I cannot figure out a problem I am having. I have the VNC server software running on my office PC. I can connect from home to my office PC from both of my laptop computers with no difficulty. But I cannot connect to the office from my desktop computer. I can make a VNC connection from my desktop computer to my laptop and from my laptop to my desktop (using internal IP addresses). Therefore it doesn't seem that this is a NAT or router or firewall problem because I am able to make an internal connection. The laptops are wireless going through a router and the desktop uses an ethernet cable, however I can't see how that would make a difference since my desktop, going through the router can VNC connect to the laptops. The difficulty appeared after I reinstalled Windows on a new hard drive. As I recall the inability to connect didn't happen for a couple of days. It was working fine for a while. Another thing I did do that was different was change versions of Windows, from Windows XP to the Home edition, but that still doesn't explain why I can make an internal IP VNC connection but not an external one, and the laptops can make an external one going through the same router with it settings. I've turned off the desktop firewall to see if that will make a difference but it hasn't. If anyone knows how to fix, I'd appreciate letting me know.
