Port Mapping

Firmware: 3.103m

The internal host with private address and port can send packets to certain Internet host through public address and port of this device’s WAN interface. NAT session is then established by the mapping of local private address/port to Internet public address/port through public address/port of this device’s WAN interface. When Port Restricted Cone NAT is configured, only mapped Internet host can access that internal host through the mapped public address/port of this device’s WAN interface. Other packets from Internet will be blocked due to there are no matched NAT sessions created in advance.
