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.
