John:
Heya. With many broadband services, the IP address given
by the ISP will change very frequently. The easiest way to work
around this is to install a "dynamic DNS" client on the target
PC you're trying to connect with. Though I don't use it, this
service seems very popular (and free):
http://www.noip.com/services/page/free/dynamic/dns
Once you've got that running, the NoIP service should
automatically track the external IP address of your friend's
broadband modem, so all you'll need to do is connect with the
"text address" name, rather that the "numerical address".
As for configuring the modem itself, your friend will need
to connect to the correct *internal* IP address of that modem (ie,
it may not be the same "192.168.1.1" default that LinkSys uses),
and then navigate to the port-forwarding page. The Kaboodle
application can be very useful here: it automatically detects all
of the devices on your LAN, and puts the ones accepting web-browser
connections into a special group. Just double-click on the device's
icon, hit "Connect", and it will start a web browser connection to
the device's configuration service. You can find that app here:
http://www.Kaboodle.org
Lastly, if the modem refuses to be configured to allow
port-forwarding, you can ask your friend to try the "Add Client"
feature of VNC. In this world, you startup a VNC Viewer in "Listen
Mode", and your friend tells the VNC Server to "Add a Client",
putting in your IP (or NoIP) address. This "reverse mode"
connection still gives you remote control over your friend's
PC, it just puts the burden of work on your end. Which is where
it sounds like it belongs. :)
Hope this helps!
