The Educational Network Builder is a simplistic tool for teaching ip-addresses, subnet masks, gateways, and routing. It was inspired when I saw someone using packet-tracer for trying to teach simple concepts. So much time was spent learning Cisco stuff and so little time on what was actually needed for simple routing.
So I created EduNetworkBuilder.
You put a number of devices on the "network", and then drag a "link" from one device to the other to connect them.
You double-click a device to edit it, where you can set the ip-address, subnet, gateway, and add routes.
The strength of EduNetworkBuilder is that it has lots of "puzzles". These start at a very basic level to teach you how the program works, and moves up through each piece of technology, showing you how it works. Then, they test your knowledge with a variety of networks where you need to figure out where the problem is and solve it. The following devices are currently supported in EduNetworkBuilder:
- Devices (PCs, Laptops, Servers, Printers, Copiers)
- Switches & Hubs
- DHCP (servers and firewalls can be configured to serve DHCP)
- Routers (and static routes on everything)
- Firewalls with NAT
- Tunnels (unencrypted)
- VPN (Encrypted)
- Wireless Devices (Wireless routers, Access points, Bridges, Repeaters)
- VLANs (VLAN routing, VLAN firewalling)
EduNetworkBuilder is a Visual Studio program. You should be able to download the current free edition of Visual Studio, open the project file, and make the project. You should also be able to download pre-compiled versions from: http://tyounglightsys.ddns.info/EduNetworkBuilder
