Desktop remote control from the web is
assisted by a a common networking
technology called NAT (also referred to
as PAT - Port Address Translation).
NAT is an
acronym for Network Address Translation.
Whatis NAT? It is a commonly used IP translation and
mapping technology. It's a
technology that allows your network to
share internet access. Using a device or
piece of software that implements NAT
allows an entire network to share a
single internet connection over a single
IP address. A single cable modem, DSL
modem, T1, broadband or any other type
of service could
connect all the computers to the
all firewalls/routers have NAT capabilities built-in that allows you
to create maps between the internet and your computer
network - this is called
web based PC remote support software, you
configure the firewall/router to port forward the TCP port
number shown on your main user page to the tech support computer.
On your main user page, enter and use the TCP port
number you prefer or use the default TCP port number already
assigned when your account was
NAT is built into
all the most
common Internet Connection Sharing technologies around.
Microsoft has built their ICS around it and every Cable/DSL
Broadband Router on the market accomplishes its job with
NAT acts as an interpreter
between two networks. It sits
between the internet and your network as illustrated in the
diagram above. The internet is
considered the ‘public’ Internet side and your network is
considered the ‘private’ LAN side. When a computer in the
private side request data from the public side (the
internet), the NAT device will open a little conduit between
your computer and the destination computer. When the public
computer returns results from the request, it is passed back
through the NAT device to the requesting computer. With our
support software the remote computer connects to your
Viewer from the Internet public side the private LAN side.
The port number used for
control support on the web could be of your choosing and does
not exclude port 443.
Port 443 is a common port number used as well since
if a network has other all other ports closed, 443 is normally left open
since it's used widely for https Internet traffic. This
document illustrates the setup required to provide to your end-users and
on-demand remote computer support
on the web.
