The problem is that things don't work that way for this particular router.
First, you are forced to select a set of computers "detected" by the router from a drop down menu list and then configure which ports are associated with that particular PC's. Problem is not all the 8 PC's appear on that list I don't know why so there's no way to select all the IP addresses from all the PC's. Unfortunately you cannot manually type the IP addresses for all PC's. Some of them are there and some aren't. Maybe I need to do a hard reset to the router so it detects all the machines connected to it.

You’ve also added a firewall exception for port 5905 on that machine (you could have just trusted the application and the firewall will figure out which port is involved). If I understand you correctly, then what’s missing is a port-forwarding rule in the router which will direct incoming connections using port 5905 to the IP address of PC5. And so on, for the other machines. Can’t remember what the 2Wire interface looks like, but many routers call these rules “Virtual Servers”. Be aware that VNC requires TWO colons if you are using anything other than the default port, so your address should be: papeleria.no-ip.org::5901 Philip Herlihy From: Roberto Meza [mailto:roberto_mez...@hotmail.com] Sent: 27 September 2009 15:15 To: christop...@custommade.org.uk; phi...@herlihy.eu.com; eshelm...@gmail.com Cc: vnc-list@realvnc.com Subject: RE: No-IP and Real VNC on multiple PC's Hello: I think I'm missing something on my 2Wire 2701HG-T router configuration or somewhere else. I can only connect to the PC (the main one) that has the No-IP client installed. I added an exception on Windows XP firewall on each of the 7 PC's So for the main PC I added the exception port TCP 5900 So for PC1 I added the exception port TCP 5901 So for PC2 I added the exception port TCP 5902 So for PC3 I added the exception port TCP 5903 So for PC4 I added the exception port TCP 5904 So for PC5 I added the exception port TCP 5905 So for PC6 I added the exception port TCP 5906 I'm entering on the VNC Viewer papeleria.no-ip.org:5901 to try to connect to PC1 but I can't. How am I supposed to configure the router? What I did was to forward ports 5900 through 5901 to the IP address if the main PC (192.168.1.71) where the No-IP client is installed. Am I missing something?
