Hello

What's the easiest way to connect to another computer from across the
internet if their computer has been issued a private IP by there ISP ?

.... the 10.0.0.0, 192.168.0.0 ...etc

Since private ip's are non routable whats the easiest way to point my
connection to their private ip number ??

It depends on how often you're going to want to do this and the reason
you want to do it. For instance, when I remote into my brother's laptop
to do family tech support I just have him plug it directly into the
cable modem with an ethernet cable. It's the easiest way for him.

If the target computer is a desktop and you want to do this fairly
often, set it up with a static private IP and do port-forwarding to it
on the router. The ports you forward depend on what remote software
you're using (XP native, pcAnywhere, *VNC, etc.).

Hello Malke

That's the exact thing I am trying to accomplish. I am currently trying to
help a person fix up their computer. There is a multitude things wrong with
it. So far have tried using the windows remote assistance program and a
couple of other free remote pc programs.

Their ISP has a unique setup using satelite broadband. Their setup uses
gateway and router technology which assigns all users a private IP. The ISP
is in the midst of changing over from assigning private IP's to public ones.
Tho who knows how long that will take.

In the mean time I am trying to think of a way to direct my connection to
their satelite broadband connection which is a private ip. Some ideas were to
create a VPN or possibly use a 3rd party program that can do this
automatically.

All we are trying to do is get a connection by using remote assistance. So
its only for a short time.

What is the easist way to do this & what are your suggestions ?
 
Didnt mention that there is no access to the router. The person who I am
helping has only a broadband modem.

For the port forwarding suggestion its a good idea tho in this scenario will
not work.
 
Hi
When an ISP is using such an arrangement you need their cooperation in order
to connect.
Your friend should call the ISP and ask for advice on this matter.

Hello Jack

Okay will pass this info on to friend and see what their ISP says.

Thanks Jack & Malke

A machine using a straight modem would not normally be communicating via a
private IP. The modem may have its own public IP when it's connected. The page

http://whatismyip.com

should be able to tell you what this is (opened on the target PC, of course)

Even so, the connection may be firewalled on the PC or at the ISP. and this
may prevent inbound connections.

The simplest way round this is to establish an inbound port on your
computer, then have him initiate the connection from his end.

You don't say what software you're using, but with VNC you need to setup
your end by opening port 5500 inbound, and running:

vncviewer -listen

Then he runs winvnc.exe (sets a default password if it's the first time)
right-clicks the system-tray icon, and makes a connection to your IP.
