ChalkTalk - ASA Firewall – Packet Classification in Multiple Contexts Mode

I recently posted a chalktalk article about ASA Firewall – Packet Classification in Multiple Contexts Mode... thought it might be useful to NW readers.

Security Contexts Overview
Cisco ASA Firewall OS software version 7.0 introduced the capability of creating virtual partitions within a single physical firewall – also known as security contexts; which provides the function of a virtualized logical firewall within one physical firewall. Each virtualized context is an independent firewall and provides all the capabilities of a regular firewall such as address translations, routing protocols, protocol inspection, ACL, and so on. With the exception of dynamic routing protocols, VPN and Multicast; these features are not supported when using multiple contexts mode.

There are two ways to set up multiple security contexts:

Multiple contexts in Routed mode (supports Shared Interface)
Multiple contexts in Transparent mode (does not support Shared Interface)

For more details, read my article on cisco.com
