Scenario 1: Inside VLAN with External Connectivity

Note
78-17612-01
A basic VLAN deployment is shown in

In this example, the network includes an internal VLAN that permits all devices
inside the VLAN to communicate with each other and an external VLAN that
permits users to communicate with devices on the Internet.
The Inside VLAN may consist of up to seven physical ports that connect desktop
computers, network printers, and other devices. The Internet VLAN consists of a
single ISP connection using an external WAN router.
This deployment is similar to the security deployments using the PIX 501. If you
already have a security deployment with PIX 501 security appliances in which
devices behind the firewall can communicate internally and externally, you can
keep the same deployment and replace the PIX 501 devices with ASA 5505
devices.
