The port forwarding feature also translates the port number in
received traffic before sending it to its destination by replacing
the received destination port value with a different one.
Port forwarding is configured using port forwarding rules.
Controls for creating, modifying, and deleting port forwarding
rules are provided. The rules are applied by matching the protocol
type and destination port number in inbound packets (packets
received from the HX system gateway) against the protocol
type/port defined in the rules. If a packet matches, the port
number in the packet header is rewritten with the port number
defined in the rule and the packet is forwarded to the IP address
defined in the rule.
