Modular Policy Framework Examples Chapter 20 Using Modular Policy Framework Applying Inspection and Connection Limits to HTTP Traffic to Specific Servers In this example (see Figure 20-2), any HTTP connection destined for Server A (TCP traffic on port 80) that enters the FWSM through the outside interface is classified for HTTP inspection and maximum connection limits. Any HTTP connection destined for Server B that enters the FWSM through the inside interface is classified for HTTP inspection. Figure 20-2 HTTP Inspection and Connection Limits to Specific Servers FWSM port 80 insp. set conns Server A 192.168.1.1 Host A 10.1.1.1 132872 Host B 192.168.1.1 port 80 insp. inside outside Server B 10.1.1.2 See the following commands for this example: hostname(config)# access-list serverA extended permit tcp any host 192.168.1.1 eq 80 hostname(config)# access-list ServerB extended permit tcp any host 10.1.1.2 eq 80 hostname(config)# class-map http_serverA hostname(config-cmap)# match access-list serverA hostname(config)# class-map http_serverB hostname(config-cmap)# match access-list serverB hostname(config)# policy-map policy_serverA hostname(config-pmap)# class http_serverA hostname(config-pmap-c)# inspect http http_map_serverA hostname(config-pmap-c)# set connection conn-max 100 hostname(config)# policy-map policy_serverB hostname(config-pmap)# class http_serverB hostname(config-pmap-c)# inspect http http_map_serverB hostname(config)# service-policy policy_serverB interface inside hostname(config)# service-policy policy_serverA interface outside Applying Inspection to HTTP Traffic with NAT In this example, the Host on the inside network has two addresses: one is the real IP address 10.1.1.1, and the other is a mapped IP address used on the outside network, 209.165.200.225 (see Figure 20-3). Because the policy is applied to the inside interface, where the real address is used, then you must use the real IP address in the access list in the class map. If you applied it to the outside interface, you would use the mapped addresses. 20-22 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
