•
The packet's destination IP address matches the specified source IP address defined in the
ACL.
•
The packet's destination port matches the specified port in the mapping.
•
The transport layer protocol that encapsulates the packet matches the specified transport layer
protocol if you specify a transport layer protocol in the mapping.
If two port mappings are configured with the same port number, transport layer protocol, and ACL,
but with different application protocols, the most recent configuration takes effect.
A mapping with the transport layer protocol specified has a higher priority than one without it.
Examples
# Create a port mapping of port 3456 to FTP for the packets matching the ACL 2000.
