Work remotely and connect to your office with a secure firewalled router

Posted on by Robert Collar

Whether for home use, or as part of a sophisticated corporate installation, a routers’ basic function is to inspect traffic on a network and decide what to do with it.

Most people understand the principles behind a low cost home modem router. At its basic level, the routers’ job is to provide the user with Internet connectivity by “routing” requests for information out to the Web, then allowing the requested information back in again.

Let’s now take the principle a stage further. Instead of a home PC requesting information from the Web and the router sending the request out and allowing it back in again, what if a packet of data or request for information comes knocking at the router’s door that did not originate from inside the home network? What if a hacker on the other side of the world originated the request and the request gets as far as your router?

The router is programmed to inspect incoming packets of data and if they do not meet certain criteria (in this case the incoming packets did not originate from within the internal network), they are dropped. And that at its simplest level is what a Firewall does.

All well and good, but how does that help a home worker or a worker out on the road to connect to the corporate network and work as though they were sat at their own desk? Well there’s only one piece of the story left to complete the picture of how data is allowed through a firewall thereby allowing a user to work from anywhere in the world with an Internet connection.

Accepting that a corporate router works on the same principle as a simple home router but with a lot more bells and whistles, it simply remains to configure the router’s firewall to drop all external packets of data (that don’t originate from within the corporate network) EXCEPT for the following……. and then open up the doors in the router that allow very specific types of traffic through to an individual PC

The doors…or ports as they are known include:

VPN (Virtual Private Network) and

RDC (Remote Desktop Connection)

Both of these methods of connecting to an internal PC or Server have their own setup requirements and security measures and both methods serve a different purpose with very different options.

The engineers at TAB Computers have a wealth of experience in configuring complex corporate routers, to allow specific traffic through the firewall with the correct levels of security and user permissions, allowing users to work remotely from anywhere in the world.

It may be that you wish to add the functionality to your existing network to allow you to work from home of an evening or weekend, or you may have a sales-force out on the road who wish to connect their iPads, Androids, Tablets or Blackberry to the corporate network, collect emails or upload and download files to a central server.

Whatever your requirements, the staff at TAB Computers can help. Please telephone a member of our team for further information or click to use the contact form and we will call you back as quickly as possible
