YOU DON'T HAVE TO CONFIGURE ANYTHING ON THE REMOTE NETWORK'S EQUIPMENT. THIS APPLIES ONLY TO
YOUR SIDE OF THE INTERNET CONNECTION FOR
REMOTE PC CONTROL ON THE WEB.
Find the steps to configure port forwarding on your router or
firewall at the following web site:

They list hundreds of routers by manufacturer and provide
configuration screen shots. If you need help please email us. We can
try to help you only if we know you're having a problem.
Ports:
Applications
running on TCP/IP open connections to other
computers using something called ports. Ports allow
multiple applications to reside on a single computer
- all talking TCP/IP. Ports are another set of
numbers AFTER the standard IP address. Applications
often hide these port numbers to reduce the
complexity of TCP/IP. Example: web services (HTTP)
reside on port 80 by default. To reach this web
site, you could type http://www.4remotesupport.com:80
into your browser. The number 80 is the default port number
for the HTTP protocol so typing it is not necessary.
There are 65535 available ports!
The settings you enter on your main page are stored in a
database so they are "remembered" and then retrieved
and used by the software that
automatically downloads to the target
remote desktop computer which you're
trying to get
remote control of to provide
remote support over the
Internet. You could change the port
and IP address any time if your network changes.
Situations that requires an IP configuration change
is if for example you change your ISP, like going from cable to DSL
or vise versa. Or you'd like to provide
remote support from
a different office or location. One of the great
features of our system is that you aren't bound to a
single IP address or network and thus you don't have
to by multiple licenses or seats. You can provide
remote desktop control on the web from almost any
location with a single account.
Port Forwarding:
A
broadband firewall/router or other NAT application (like
Microsoft ICS)
creates a gateway between your internal network and
the Internet. A firewall keeps unwanted traffic from
the Internet away from your LAN computers. A
‘tunnel’ or "route" can be created through your firewall so
that remote computers on the Internet can communicate
to one of the computers on your LAN using a single
port. This is handy for running web servers, game
servers, ftp servers, video conferencing, and for
online desktop remote support
software.
This is called port forwarding. One of your
computers could run a web server (port 80) while
another computer could run an FTP server (port 23) -
both on the same IP address. For
computer remote support
purposes, the port forwarding is for the client
software that's run on your end-users'
computer
to connect to your Viewer that's running on a
support computer (your computer) connected to the LAN.
On
your profile page, you input your Public or Internet
IP address in the IP address field. The port
forwarding to enable the online
remote control
software is only required to be done once and only
on your side. TCP data
passing through the port
you selected and entered in the port field on your profile page is
forwarded to your computer through the router. When
supporting
remote computer
systems on the LAN, private WAN, or
through a VPN, you use your computer's private LAN
address and port forwarding isn't required.
Port forwarding can
sometimes be difficult to configure, but provides a
relatively safe way of running a server or a remote
support viewer station from behind
a firewall. This is the method we recommend for our
online remote support software
service. Since only a single port is exposed to the Internet, the
computer is easier to secure. Additionally, port
forwarding allows you to run multiple kinds of
servers from different computers on your LAN. (see
