Finally, I manage to learn Cisco Configurating with one of the vendor. Lesson one is ...how to access Cisco router by using a Linux system via console (cable connection).

Lesson one detail is learn how to apply Access Control List - means to block what traffic can come in and go out. So I manage to block all staff from surfing a popular website call NeoPet.

Quite happy after many days of research, but in the middle of configuring, some hicaps and cause all internet connection to be down. But I gain some experience.

Hurray....can't wait 6:30 pm to arrive.
