This is my first post about the Mikrotik Product.  I will be putting up several examples in the coming weeks and months, so if you don’t see what you are looking for, be sure to contact me directly.  Leaving a comment is fine, but not likely to be “answered” unless it is a clarification for the specific article.

Welcome to my blog!

Sunday, June 22nd, 2008

This blog will contain several tutorials and thoughts about various networking devices and technologies. Part of the intent here is to share some how-tos using various products. Since I am most familiar with the ImageStream and Mikrotik products, you will find many of my tutorials revolve around these products. Also, I will be posting various general networking tutorials. If you can think of a specific tutorial you’d like to see written up, by all means, please let me know by email or by phone. My main consulting website is here.
