Business Internet - Remote Access
Support
 | ||||
MyWebEx PC PRO is a subscription service that we purchase from WebEx. They take care of all the security issues, such as proper encryption and log-in when you are on public networks and how to get around our firewall.
It is avoids the security, performance, and special software problems of virtual private networks. We provide it only to those employees whose job requires them to access information on our networks from remote locations.
You must have a work-station assign-ment on our network with direct access to the Internet and a cell phone.
General
| ||||
1) Log-onto the Internet from any computer (local), preferably one with a high-speed connection, such a Wi-fi 'hot spot," Cyber Cafe, customer, hotel, or at home.
2) Browse to the MyWebex Web site and log-in.
3) WebEx will download a temporary "plug-in" to that Browser that will allow you to continue the connection with 128-Bit Encryption, which is critical on public sites.
4) WebEx will place a call to your cell phone, which we registered with them when we setup your access privileges.
5) Key-in you PIN on your cell phone and WebEx connects you to YOUR remote computer on our network.
6) You can now operate your remote computer from this local computer as if you were sitting at the keyboard and mouse. Any capabilities you have on your remote computer you now have on this local computer, such as the ability to run the MRP System, review Quotation history, review operating manual, progress reports, etc.

We provide access to our business networks using the highly secure and highly flexible service of WebEx. If you have access to an Internet Browser and your cell phone, you can log-on and operate your computer on our network from almost any other computer in the world.
We provide this service on a "need to have" basis. Please read Procedures below for more information on how this capability works.

Controlling a computer behind a Router using NAT requires a special setup. I have included it here although it is not part on our system.
Open the router's setup screen, typically a Web page located at 192.168.1.1 Go to the Port Forwarding screen (sometimes called Applications & Gaming). Each entry on this page represents a different service to be routed; simply add a new one, specifying the appropriate port number along with the IP address of the PC to be controlled.
The computers behind the NAT must have Static IP Addresses. You can't use DHCP services of the Router. You must know the Port that the Remote Access program uses. For example, VNC uses 5800, 5801, 5900, or 5901.
Give the entry a name (e.g. "remote" or "Dimitri"), and click on Save Settings.
These exceptions somewhat compromise the security of our firewall, avoid leaving them open when not using them
If the remote computer is running Windows XP SP2, the built-in Windows Firewall is likely active. Go to Control Panel | Windows Firewall and, if the firewall is enabled, choose the Exceptions tab. Click on Add Port, type the port number, come up with a name for the exception, and click on OK.
