it may be that you have old ios images which do not support zbf. mixing zbf with cbac is &nbsp;not recommended. have a look here<br />

Sorry, I incorrectly posted that SDM first supported Zone FW in 2.3. &nbsp;Zone FW support was introduced in SDM in 2.4:<br />

Hello,<br />
Can someone please help us identify why we have multiple Cisco routers some with the ZBF on and some with the older firewalling feature within SDM. &nbsp;I think it is something to do with the version of the IOS or the version of the SDM but I cannot find anything from Cisco which explains why we have these differences,<br />
Can someone help please?<br />
Thanks!

Cisco Zone Based Firewall and SDM

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
