Steve Smith, host of your Technology Questions Answered, explains how to restrict access to your internet and network gateway using the media access controller address of all devices capable of network access regardless of connectivity.

This is Technology Questions Answered, and for those who don't know who I am, I'm Steve Smith, aka Zed Axis, the host of the show. My personal mission is to bring new concepts, tools and knowledge to those who will greatly benefit these, and I do this by using the internet to showcase my weekly show, available through YouTube, iTunes, Feedburner, and numerous other syndication services.
This week, I tackle issues that arise when unauthorized computer connection through gateways like routers, and offer a simple solution that may be a little time intensive at the beginning, but increases overall network security, prohibits access to all unregistered machines connected wirelessly or connected physically to your gateways, and reduces the total overall abuse of internet bandwidth from external sources. This prevents all access to networks from employees using their own equipment like laptops, net books, tablets, cellphones, etc...
This will prevent virus and malware infections, keep employees from downloading illicit materials, reduce bandwidth traffic, and prevent unauthorized file transfers. If you want to deploy an authorized connection policy for employees, you can also control which devices can connect legitimately on the network.
This also allows you the ability to accurately define the traffic type, and log computer traffic accurately by knowing which devices are abusive on the internet.
Want to know what I am talking about? I am referring to media access controller address filtration, also known as MAC Address Lock, or network filtering, depending on which company you use for your gateway needs.
The positives of this technology are:
The Negatives of this technology are:
Now to deploy this method only requires that you have:
To deploy within the gateway, if all the machines, and only the machines you want, are connected and online, you usually can select them, and add them almost automatically the first time, this may require that you define static IP addresses for each machine, which is great for logs, but not really required. If you want to use this to monitor traffic loads, defining static IP addresses will make everything easier.
Now, you can also verify a machine's MAC address by visiting each of the computers, and verifying the network connection status, under the support tab, select details, and take note of the physical address, also know as the MAC Address. Then, you may enter each MAC address, manually, as well.
The majority of gateway routers will have an option called network filter, MAC address lock or MAC address filtering. This is where you will enter the information of each authorized machine to start filtering your network traffic and keep the unauthorized users out.
Now, you only have a few precautions to follow:
Now, if you followed all my suggestions, you should enjoy a faster, more reliable network environment where bandwidth usage shall be easier to monitor, and savings in costs should be on your way. This applies not just to businesses, but also to family and co-operative home situations.

Playing yet again as Talion, infused with the spirit of the Elf Lord Celebrimbor, you continue you quest against Sauron with a new ring forged, free of his corruption. You start the story seeking out Shelob, a Spider Queen who has recently kidnapped Elf Lord Celebrimbor, and you must make a heavy sacrifice in order to return in to your body. From then on you must fight against the hordes of Orcs commanded by Sauron to free Mordor, starting with the city Minas Ithil, where the Palantir is located. The Palantir is a valuable tool that would allow anyone to see what they would like to see, making it a great tool in winning the war over the entirety of Middle-earth. Your task, prevent Sauron by gaining the upper hand, or everything is lost.
