NAT (Port Mapping)
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, that is, the Internet.
Security on the private network (LAN) is increased since most broadband routers are pre-configured to
stop attempts to access the private network (LAN) from the public network/Internet.
Use NAT traversal when your network cameras are 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 is forwarded to the network camera.
NOTES:
• For NAT (port mapping) to work, this must 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.
