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,” ”Inter-
net Gateway,” ”Broadband sharing device” or ”Home firewall,” but the essential purpose
of the device is the same.
