Some time ago, I wrote an article giving an overview of how to configure VLANs on a Cisco Catalyst 3550. I did not go into detail on firewall configuration because this was not necessary for me at the time using a PIX 515e. However, things have changed on my network as they often do and we are now utilizing an Untangle firewall which does not currently support the use of VLANs. I have however found a workaround that functions perfectly in my environment without compromising security or efficiency. One solution would be to revert back to a single subnet; however, we would lose the benefits of network segmentation that reduces collisions and optimizes our network performance. For the sake of this discussion, I am going to build upon the discussion in the previous article located here and only focus on the configuration of Untangle to meet the needs of the network designed in that article. It would be wise to review that article before continuing with this discussion. |

Microsoft has kicked off its new ad campaign "I'm a PC" where they have a dozen or so people including Deepak Chopra and Eva Longoria explain why they are a PC. Apparently, the ad is intended to blow away the stereotype portrayed in the "I'm a Mac, I'm a PC" ads from Apple. (read more on the story here). The humorous thing to note is the images used in the Microsoft Press Pass to kick off the campaign were generated on Mac computers using Adobe Photoshop CS3 Macintosh. (read about this here). Apparently, even Microsoft's ad agency realizes that Macs are the way to go. Or is Microsoft in serious need of psychoactive medication? |

Many network administrators will discover over time that the amount of traffic on their network exceeds the capacity of their switches. To relieve some of the strain, improve speed for users, and provide security for the infrastructure it becomes advantageous to segment their network into virtual local area networks. The process is simple, but requires the environment to be thought out in advance. |

For the longest time, my users have complained that they cannot use the Out of Office Assistant in Outlook 2007 with Exchange 2007 as the backend server. It damn near took a voodoo ceremony with water never run through a pipe, the head of a brown chicken and a pentagram drawn on the floor with an iron based nail polish, but I finally found a solution to the problem. |

I have seen similar instructions selling on eBay for $4.99 on Buy-It-Now (here and here), but I question the legality of selling this information for any price. First of all, the modification is easy to figure out for any lay person with a nearby RadioShack. Second, it is illegal in most jurisdictions to bypass the video cut-off of an in-dash DVD player so that the driver can watch DVDs while driving, though experience tells me that there are some out there stupid enough to want to do just that.
Because I am an ethical darwinist, I will tell you how to perform this hack and I won't charge you a dime. If your IQ is such that you feel it is safe to drive while watching a movie, just make sure not to take anyone else out with you. But for passengers in the front seat, there is only one way to enable them to be entertained by watching their favorite movies on long road trips. Here is how to do it. |
