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”, 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 traversal 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.
