How to turn a Cisco Router into ASA..

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Guess what your Routers  support zone-based policies, which really helps with multi-interface restrictions (rather than just one outside & one inside interface with individual access list applications). Likewise, it now supports application inspection to catch those scandalous peer-to-peer programs.

Cisco IOS® Software Release 12.4(6)T introduced Zone-Based Policy Firewall (ZFW), a new configuration model for the Cisco IOS Firewall feature set. This new configuration model offers intuitive policies for multiple-interface routers, increased granularity of firewall policy application, and a default deny-all policy that prohibits traffic between firewall security zones until an explicit policy is applied to allow desirable traffic. For more details do access this document from Cisco.

    Hey, I have a cisco 1841 router in our school but it doesn't have the security bundle (firewall, NAC, etc..) that the device is also capable of. Can you help me upgrade this router? Thanks
