Cisco Security Lab

As I am quickly approaching the day when I will take my CCNA Security exam I wanted to get more hands on experience with actual Cisco gear.  Something that I could try out everything I have learned, mess things up really bad, fix the problems and see how secure I can make the test network.

My previous lab had most of what I needed, however I needed to mainly upgrade my routers as they just wouldn’t cut it for what I was looking to do.  I had three 2500, and two 2600 series routers.  So I ordered two 1841 Routers, and three WIC-2T cards, and five serial cables.

Once all the equipment arrived I went to configuring the lab.  I used the two 1841 Routers to connect to the Cisco Switches, and set them up for two different networks.  Router 3 was placed on the 192.168.3.0 network, and Router 1 was place on the 192.168.1.0 network.

The wireless APs.

Router 2 was my Cisco 2811 Router, and was connected to the two 1841 Routers with serial cables.  I setup EGIRP on the routers, and setup some routes and then it was time to setup a way to connect to my end switches without having to be in the closet with the routers.  I have two Linksys Wireless APs that I decided to use.  I configured them to be on each of the networks, after that was done I was able to connect my laptops to either AP.  I then tested to make sure connectivity was working across the entire network and was able to ping the laptop on the other side of the network without an issue.

Now that the network is up and running I can start working on the Security Labs from the CCNA Security Lab Manual.  I am really looking forward to honing my skills with the network and trying out everything I have learned.
