FWSM鲜为人知的强悍之处在于....
从Software Release 3.1(x)开始,支持如下新功能:
Mixed L2 & L3 mode support
A mixture of L2 and L3 modes on the same FWSM is allowed, which enables flexible network deployments.
同一个FWSM模块配置多个虚拟防火墙,并且路由模式和透明模式可以共存-----够牛X

Multiple pairs of L2 interfaces per context
The number of supported interfaces in transparent mode is increased from a single pair up to eight pairs pairs. This improves scalability and reusability of L2 contexts.透明模式不仅支持多接口,而且支持8对也就是16个,非常强悍----解决了思科人心中永远的痛,过瘾!!!



从Software Release 3.2(x)开始,支持如下新功能:
Transparent Firewall NAT Support ----也够强悍的吧!!
You can now configure NAT for a transparent firewall. This feature extends the NAT/PAT functionality to transparent mode thereby reducing the need for adding a new NAT/PAT device in the network. This feature is also very useful in cases where multiple virtual routing and forwarding (VRFs) with overlapping addresses are used. NAT per VRF is not supported on the Catalyst 6500 series switches and the Cisco 7600 series routers.
Introducing NAT support for transparent firewalls addresses the NAT per VRF requirement. Transparent mode offers the capability to run routing protocols through the FWSM with minimal configuration.
