NAT Traversal
A broadband router allows devices on a private network (LAN) to share a single connection to the Internet. This is done by forwarding network traffic from the private network to the “outside” i.e. the Internet. Security on the private network (LAN) is increased since most broadband routers are
Use NAT traversal when your AXIS 231D+/232D+ is located on an intranet (LAN) and you wish to make it available from the other (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an external HTTP port in the NAT router will be forwarded to the camera.

Notes: • For NAT traversal to work, this must also be supported by the broadband router.
•The broadband router has many different names: “NAT router”, “Network router“, Internet Gateway”, “Broadband sharing device” or “Home firewall” but the essential purpose of the device is the same.
Enable/Disable - When enabled, the AXIS 231D+/232D+ will attempt to configure port mapping in a NAT router on your network, using UPnP™. Note that UPnP™ must be enabled in the camera (see System Options > Network > UPnP).
Use manually selected NAT router - Select this option to manually select a NAT router and enter the IP address for the router in the field provided.
If a router is not manually specified, the AXIS 231D+/232D+ automatically searches for NAT routers on your network. If more than one router is found, the default router will be selected.
Alternative HTTP port - Select this option to manually define an external HTTP port. Enter the port number in the field provided. If no port is entered here a port number will automatically be selected when NAT traversal is enabled.
