6.2.5 NAT EXCLUDE IP Setup
The purpose is to exclude certain flows of traffic from translation. Any packets (going from
inside or outside) matching the NAT EXCLUDE IP do not require NAT translation entries to be
permitted by the router.
6.2.6 NAT Port Trigger
Port triggering is a way to automate port forwarding in which outbound traffic on predetermined
ports ('triggering ports') causes inbound traffic to specific incoming ports to be dynamically
forwarded to the initiating host, while the outbound ports are in use. This allows computers
behind a NAT-enabled router on a local network to provide services that would normally
require the computer to have a fixed address on the local network. Port triggering triggers can
open an incoming port when a client on the local network makes an outgoing connection on a
predetermined port or range of ports.
