Nat - NetComm 4G100W User Manual

NAT

The NAT page is used to configure the Network Address Translation rules currently in use on the router. The router is in NAT mode
by default.
This is only needed if you need to map inbound requests to a specific port on the WAN IP address to a device connected on the
Ethernet interface, e.g. a web camera.
