For example, hosts on subnet 192.168.21.0 might run HTTP services on non-standard port 8000, while other traffic through the firewall uses the default port for HTTP services, which is port 80. Host-specific port mapping also allows you to apply PAM to a specific subnet when that subnet runs a service that uses a port number that is different from the port number defined in the default mapping information. This means that you can map port 8000 with HTTP services for one host, while mapping port 8000 with Telnet services for another host. With host-specific port mapping, you can use the same port number for different services on different hosts. In some environments, it might be necessary to override the default port mapping information for a specific host or subnet. User-defined entries in the mapping table can include host-specific mapping information, which establishes port mapping information for specific hosts or subnets. This section contains the following sections: Host or subnet specific port mapping is done using standard ACLs. PAM also supports host or subnet specific port mapping, which allows you to apply PAM to a single host or subnet using standard access control lists (ACLs). Now, PAM allows network administrators to customize network access control for specific applications and services. Previously, CBAC was limited to inspecting traffic using only the well-known or registered ports associated with an application.
The information in the PAM table enables Context-based Access Control (CBAC) supported services to run on nonstandard ports. Using the port information, PAM establishes a table of default port-to-application mapping information at the firewall. PAM uses this information to support network environments that run services using ports that are different from the registered or well-known ports associated with an application. PAM allows you to customize TCP or UDP port numbers for network services or applications.
