First of all, I've read all the relevant questions here I could find... I use RealVNC to connect to my computer at home - everything worked without any problems, but today I couldn't connect from work. Over the weekend I was OC-ing my computer and now I noticed that the internal IP was changed to (from which is a bit weird as I have reserved the 0.2 address to my MAC. But anyways, I've to change the port forward to 0.6 but that didn't work. After router reset, I got the 0.2 address back so I've changed the port forward back to, but I'm still getting connection refused error. Windows firewall is set correctly, the VNC server is running as I can connect via the internal address but connecting using the external IP gives me an error.

Any suggestions?


Edit: OK, I see I cannot connect from local network using external IP, but when I use RealVNC iphone app and 3G connection only I can connect which is all I need ...

Your MAC is the same? Very weird you got a different IP. Is your network secured? Check the connections you have. – user127350 Apr 10 '12 at 19:30
hi, yes MAC is the same, but I wonder whether the OC-ing and moving hardware around a bit got the router confused for one restart... – scibuff Apr 10 '12 at 19:38
What to be confused about? It looks for the MAC. LOL on your edit. That is even weirder. Your ISP might block some incoming connections from certain IPs, that's all I can figure from what you're saying. – user127350 Apr 10 '12 at 19:46
Did someone else reset your router to play a joke on you? That would cause your router to stop working and give you a different IP, but normally it would change the first three octets of the IP to 192.168.1.x depending on the manufacturer of the router.... – David Apr 11 '12 at 19:30
