Applying Inspection and Connection Limits to HTTP Traffic to Specific Servers
In this example (see Figure 32-3 ), any HTTP connection destined for Server A (TCP traffic on port 80)
that enters the ASA through the outside interface is classified for HTTP inspection and maximum
connection limits. Connections initiated from Server A to Host A does not match the access list in the
class map, so it is not affected.
Any HTTP connection destined for Server B that enters the ASA through the inside interface is classified
for HTTP inspection. Connections initiated from Server B to Host B does not match the access list in the
class map, so it is not affected.
Figure 32-3 HTTP Inspection and Connection Limits to Specific Servers
See the following commands for this example:
hostname(config)# object network obj-192.168.1.2
hostname(config-network-object)# host 192.168.1.2
hostname(config-network-object)# nat (inside,outside) static 209.165.201.1
hostname(config)# object network obj-192.168.1.0
hostname(config-network-object)# subnet 192.168.1.0 255.255.255.0
hostname(config-network-object)# nat (inside,outside) dynamic 209.165.201.2
hostname(config)# access-list serverA extended permit tcp any host 209.165.201.1 eq 80
hostname(config)# access-list ServerB extended permit tcp any host 209.165.200.227 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
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
inside outside
