Dear VNC Support. I use VNC free edition via a Viewer to remote my other PC, but it does not success. For example, the remoted PC , IP : 219.130.32.180 with a router and Local IP : 192.168.1.105. I enter Server: 219.130.32.180 in "VNC Viewer : Connection Details" windows. I believe I miss something, please advise Thanks in advance Best Regards, Edmund
