Techy articles for the month of January

Hey my techy readers,

I will now be writing only one article per month summarizing all the techy articles I write for Intense School so that should drive down the number of techy posts on this blog tremendously. Did I hear you guys shout hallelujah? *hehe*

For the month of January, we have the following topics:

  • Route maps: Learn the fundamentals of route maps here.
  • Bridging VPNs: This series has four parts: part 1, part 2, part 3 and part 4. It looks at the following scenario: Site A and Site B have a site-to-site VPN connection between themselves. Site C is a new site that needs to also have VPN access to Site B but for some reason, this new VPN access has to go through Site A which will then route it to site B.
  • Site-to-Site VPN with overlapping subnets (on Cisco ASA): This one has two parts but only the first part has been posted for now. It discusses what to do when you need to set up a VPN tunnel between two subnets using the same IP address space.

I actually didn’t write a lot in the past month because I was busy with other stuff. Let’s see how February plays out. Happy new month in advance!


Techy post: GNS3 connection to host machine

Hi guys, it’s that time again where I feed my techy appetite. Those in the networking world would agree with me that GNS3 was one of the best things that ever happened to us and it keeps getting better. Not only is it useful for certification exams, it is very useful as a quick lab setup for a test environment.

In these articles (part 1 and part 2) on the Intense School site, I have walked through connecting GNS3 devices such as routers and firewalls, to your host machine and even to a LAN to which your host machine is connected to. Go over there and find out the benefits of these for yourself.

I actually wrote these articles as a precursor to an upcoming series on the Cisco Configuration Professional (CCP) tool especially useful for those planning to take the CCNA Security exam. If you want to learn more about the CCNA Security exam, classes are available at Intense School!
