⑥ ⑥ ⑥ ⑥ 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.
• NAT traversal Settings:
- Enable: when enabled, the Network Transmitters attempt to configure port mapping in a NAT
router on your network, using UPnP™. Note that UPnP™ must be enabled in the network
camera. (Please see Setup > System > Network > UPnP, on "4.5.5 System > 4) Network > ④
UPnP".).
