Understanding Cisco Secure Firewall Services Module 4.x Routing and Feature Enhancements

Chapter Description

This chapter discusses the key additions to the Cisco Secure Firewall Services Module (FWSM) 4.x code.

Summary

The release of 4.x adds some very significant enhancements. The addition of EIGRP now provides the capability to integrate a FWSM into an EIGRP network without having to redistribute routes into other routing protocols. RHI allows static routes, NAT pools, and connected routes to be propagated to the routing engine on the host-chassis dynamically. Regular expressions give you the opportunity to match traffic based on custom signatures. Application inspection improvements and SNMP additions, option 82 support, and filter enhancements, make the FWSM an even better option to secure your valuable assets.
