Description PAM supports two mapping mechanisms: general port mapping and host port
mapping based on basic ACL. The former is to establish the mapping relation
between a user-defined port number and an application protocol. For example,
mapping the port 8080 to the HTTP will make all the TCP packets destined to 8080
be regarded as HTTP packets. The latter is to map the self-defined port number to the
application protocol for the packets from some specific hosts. For example, you can
map the TCP packets using the port 8080, which destine to the hosts residing on the
segment 1.1.0.0 to be the HTTP packets. The range of hosts will be specified by the
basic ACL.
