Blocking ports to restrict online access becomes really useful when you’re running an office and your employees seem to do less work and are caught engaged in chatting or checking scraps on facebook. This is high time to restrict online access by blocking ports on all your office computers. You can have it done with the help of your IT staff (if you already have someone employed solely for this purpose). If you don’t want to hire an IT consultant or you may already have ways to put off employees from drifting into the alluring time sinks of IMs, network gaming, video strips, and more, even then this article will help you. Here we tell you an easy way to systematize a range of blockades on your own, without having to appoint anyone. I’ll explain the easiest technique first, port blocking.

Your PC segments its networking traffic across thousands of virtual ports, sort of like strands of thread in the same rope. AOL Instant Messenger keeps things orderly by communicating on one port, web traffic goes through another, and FTP downloads get their own path. Almost each and every service gets routed to a separate port; visit Wikipedia for a growing list of them all.

When you know which applications use which ports, you only have to constitute your router firewall to obstruct access from your network. Follow your router’s commands to visit its configuration page; you’ll possibly log in through a web browser. Visit the firewall settings page to control specific services. For instance, block (or drop) access to port 5190 to stop AOL Instant Messenger, block 3724 to prevent access to World of Warcraft, and block 5001 to prevent access to Slingbox video.
