Purpose of Class
This class teaches students why they should set up a separate Computer Lab network on their home network if they will be creating test servers and networks. It also explains the basic concepts such as; Port Forwarding to Multiple Layers of Routers, the Need for Different IP Subnets on the Same LAN, and that Conflicting Server Services can cause odd problems.

Class Notes
Reasons for a Separate Computer Lab Network– DNS and DHCP issues, performance problems
Lab Network must be on a different IP Network then other LAN Networks. 192.168.1.x, 192.168.2.x, 192.168.3.x
For access to servers form outside world port forwarding on your ISP Router must be pointed at the Router for your Lab Network
Any $60 Linksys Router can be used to create a lab network.
Lab Network Router External Interface needs to be configured to be on the same network as the ISP Router’s Internal Interfaces.
