Basic Deployment Using Two Vlans - Cisco ASA 5505 Getting Started Manual

Chapter 3 Planning a VLAN Configuration

Basic Deployment Using Two VLANs

78-18003-02
For most deployments, you only need to create two VLANs: an Inside VLAN and
an Outside VLAN, as shown in Figure 3-1.

In this example, the network includes an inside VLAN that permits all devices on
the VLAN to communicate with each other and an outside 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. In this scenario, the Outside
VLAN consists of a single ISP connection using an external WAN router.
In Figure 3-1, the Inside VLAN uses four switch ports on the ASA 5505 and the
Outside VLAN uses only one. Three switch ports are unused.
