Application Port Binding Overview

Application port binding on FW card is used to bind application
layer protocol and port. When FW card performs deep content
detection to application layer protocol, it will check these packets
and perform corresponding processing.
System defines parting bindings between application layer proto-
cols and standard ports by default. In case some application layer
protocols use non-standard ports or sub-connection (such as FTP)
is contained, user must bind these ports and application layer pro-
tocols, or FW card will fail to detect and process these packets.
For example, there is one FTP server in intranet SSN area and
non-standard port 2200 is used to provide FTP service for intranet
users. In case application port binding is unavailable, FW will not
process packets of this connection. Customize application protocol
port binding policy.
System has the following default standard ports:
