Redirecting Users for Non Pay (or any other reason)…

Tuesday, April 3rd, 2012
One common question I see on forums and other places is how you can use Mikrotik to redirect non-paying users to a "pay me now" page.  This tutorial will cover one of the methods that you can use to accomplish this seemingly confusing function. (more…)

When AND Why Proxy-ARP

Tuesday, June 1st, 2010
In my training classes, I go to great lengths to teach when and why proxy arp is necessary on an interface.  I have seen (and answered) numerous questions on my mailing lists regarding proxy arp and it seems it is time to create an article that I can just point people to.  I will focus this article on Mikrotik RouterOS (as many of my articles are), but it should be noted that proxy arp is not unique to Mikrotik.

Training classes scheduled ONLINE

Friday, October 17th, 2008
I recently announced 2 new training courses that I will be offering online.  Details can be found at the registration pages linked below.  You can view ALL currently available courses HERE The first course is a WISP Basics course.  This course is a discussion of IP basics and an RF Primer.  The IP Basics portion is a detailed look at network fundamentals.  This course is perfect for those that are new to the WISP business or anyone who wishes to learn more about how data flows over an IP network, including wired and wireless networks.  There is a lot of detail in this course and it is possible that it will extend to about 2.5 days.  Registration for this course is HERE The second course is our Mikrotik Standard training course adapted for use online.  The online course is not exactly the same as our live training, however, it is similar in many ways.  The content of the course is mostly the same, however, the labs are rewritten to accomodate an online environment.  This is a 4 day training and is a detailed look at most of the features in RouterOS.  Registration and more information is HERE. Because the training is online, there is no need to make travel arrangements.  Online training offers you the ability to have multiple employees trained for the price of one.  Online training offers you the ability to learn from the comfort of your own office space.  The training we are offering is of the highest quality and should not be confused with other training offers currently in the marketplace.  We offer: * The most mature (over 4 years in development) training material * An expert in networking as trainer (not just Mikrotik) * An experienced trainer (I've been teaching in one form or another since 1998) * An experienced ISP with the expertise to adapt materials to the WISP network You don't have to spend HUNDREDS of dollars more in order to get quality training.  You don't have to spend MONTHS learning this material.  If you've ever considered attending a live training, but have been waiting for one to be "near you", then this is your chance to see what it's all about.  Registration information is available for both courses HERE.  Seating is limited and the special discounts won't last long, so don't hesitate.

So, how does routing work, anyway? (Part 1)

Thursday, September 11th, 2008
It's a question that I get from time to time and it's time to answer here.  If you understand the fundamental principles of networking, then all the other parts of building and maintaining an ISP network (wired OR wireless) are much simpler.  In this series of articles we will discuss the processes that make IP networking function by delving into the fundamentals of how subnetting works, how a router USES subnet information and the very important arp process. This topic is an easy topic to understand, but it is difficult to organize the materials and ideas needed to easily explain.  This is because there are so many pieces that are related and understanding one part is necessary to understand the next.  You, as a reader, may need to read this article more than once in order to fully understand all of the parts.  We will use the following "talking points" to cover this topic:
  1. Networking basics - what is needed to make two or more computers communicate?
  2. What is a router and why is it a necessary component in a  network?
  3. Subnet masks and what they mean.  What, exactly, IS a subnet address and why do I care?
  4. ARP - what is it and what does it do?
  5. Wrap up and tying up the loose ends.
