LAN / WAN IP address with RealVNC?

Question

I need help getting up and running with RealVNC. I have a home network, and I know the LAN IP's for my two computers. I can run VNC between the two using the LAN IP. I have the info for my WAN IP, but how do I use this to access other computers on the internet? I have tried to do this with my two home computers, a they both access the internet through the router. I need to be able to connect to my relative's computers in order to help them with computer issues, but I have not been able to do this so far! Is there any way to test this out with my two home PC's?

Answer 1

As long as the computer you're trying to connect to has the RealVNC server, and your computer has the RealVNC Viewer, you should be able to connect by putting the server computer's IP address in the box.



1. Download the RealVNC server to the target computer.

2. Forward the correct ports on the target computer (usually 5900, I believe)

3. Put in the target PC's IP address into the RealVNC Viewer

4. Connect



NOTE: To get the IP address of a computer, have someone go to http://whatismyip.org



Hope this helped!

For connecting to your relatives computers when they need help you could consider using UltraVNC's Single Click option ( http://www.uvnc.com/addons/singleclick.html ). You would setup a pre-configured version that you send to them and then when they need help they initialize a connection back to you. This way your relatives don't need to do anything with their firewall/router settings (but you would on your end).



Regardless, to connect to a computer outside of your LAN, the remote computer will need to have it's port 5900 open to the outside world - i.e. setup a port-forwarding rule in their router and potentially in any software firewall they may have. Since you'll also need to know the public IP address of the other end, if you're going to do it often using a service like DynDNS.org would probably be wise. If it's only every once in a while just have your relatives visit a website like www.IPChicken.com to find out their public IP. Also, if you go the UltraVNC Single Click route, you'll want a DynDNS account for yourself and put that in the UltraVNC SC config so that if your IP changes it will still work.



REMEMBER, if you're opening up your VNC to the internet, lock it down with a good strong password and if possible use one of the encryption add-ons!



Alternatively, if it's available, just use the Windows Remote Desktop client & server (Win2000/XP Pro) The performance will be better.

Any machine you want to access needs the vnc service running. You need to open the vnc ports in the firewall and set up port forwarding on the router pointing to the machine you wish to access. You need port 5900 for the vnc client connection and 5800 for the web access on any Windows machine. This is unfortunate, as if you want to access more than one machine it will not work. You can point each router at one machine. You could then access any other machines by vnc from the first. It can make the vnc Windows a bit confusing to work with. If you leave these services running you are exposing your machine to severe risk of attack from the internet as vnc ios not that secure. It handles logon as open text with no encryption. This makes it very easy for someone to see your connection and note user names and passwords.

one side of the router has your WAN, the other side will be a network like 192.168.1.(1-255), Your cameras will have ip addresses like 192.168.1.10, 11, 12, 13 The mask will be 255.255.255.0, the default gateway 192.168.1.1 (the LAN side of the router) you will probably have to NAT the incoming traffic, so a request from your WAN port for port 200 will get forwarded to the correct IP address:200, each camera will use a different port and be mapped to a different LAN ip address. wanport:200 goes to 192.168.1.10:200 wanport:201 goes to 192.168.1.11:201
