Connecting a private network is an important task, but a system administrator also needs to "tweak" the network to make it '''convenient to use''', make it '''safer from unauthorized access''', and use troubleshooting utilities to help '''troubleshoot''' network connectivity problems as they occur. This investigation will expose you to some useful tricks and utilities to help accomplish this task. '''NOTE:''' Lab 7 requires that you understand these concepts and have a good general understanding how to use these troubleshooting utilities (like '''netstat''' and '''iptables''').
