Confused about Router Settings?

Postby 1xOdPbkVUjCbcnw8mjSh » 2011-10-13 05:04

Hello, I've begun learning about managing ports so that I can use UNVC.

I follow the directions here for port forwarding: http://portforward.com/english/routers/ ... ys/WRT54G/

I arrive at the page that looks something like this:

When I check my IP address using various sites, it shows as 25.8.13.103

I don't know what I'm supposed to put in the blank box as my IP address. The IP address I'm supposed to put there clearly begins with "192.168.1."

I don't understand how I can have multiple IP addresses on the same computer or how I would find this one, which I need in order to forward port 5900.

I can't find the answer online; so any assistance would be greatly appreciated.

The key to understanding this is first that, because you have a router, you have a LOCAL NETWORK at your home or business. That local network has its own IP address range, typically 192.168.x.1 through 192.168.x.254. Every device on your local network (your computers, your network printers, your Wii or XBox, your WiFi enabled phones, etc.) is given an IP address in that range by the router.

And second, you have a PUBLIC IP ADDRESS that exists and is visible on the Internet. The world can't see your 192.x.x.x addresses (they're "reserved" exactly for that reason) but they can see your single public IP address -- the 25.8.x.x one you listed.

Your router holds BOTH the public IP address AND a 192.x.x.x address on your LOCAL network (usually the router is 192.168.x.1.) The machines behind the router do NOT know about the public IP address; they have only their 192.x.x.x address.

You can check the local IP address of your PC by clicking Start, typing "cmd", hitting Enter, and then typing "ipconfig" at the command prompt. You can ALSO see all existing assigned local network IP addresses in a status page on many routers.

Because you want to port forward, it is better to set a STATIC LOCAL IP address on your computer (so the local IP address does not change). There should be plenty of instructions at PortForward.com and other sites for how to do this -- you use Windows' network control panel.

And then, yes, you enter the 192.168.1.x address (the one displayed by ipconfig as I described) and the VNC port you're using into the Port Forwarding screen for your router.

Good luck!

Thanks! I've set a static IP address and forwarded the port for my computer. Now I have to do the same for the server computer.

No, you only need to forward a port for the "server" computer, which in VNC parlance is always the one BEING CONTROLLED. The exceptions to that are reverse VNC connections and repeater connections.
