Host Name Configuration

The video encoder can be accessed using a host name, instead of an IP address. The host name is usually the same as the

assigned DNS Name.

For more information see the online help .

Link-Local IPv4 Address

This is enabled by default and assigns the video encoders an additional IP address for use with UPnP™. The video encoder can

have both a Link-Local IP and a static/DHCP-supplied IP address at the same time – these will not affect each other.

HTTP and HTTPS

The default HTTP/HTTPS port numbers (80 and 443 respectively) can be changed to any port within the range 1024-65535.

This is for example useful for simple security port mapping.

NAT traversal (port mapping) for IPv4

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 video encoder is 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 video encoder.

Notes:

• For NAT traversal to work, this must be supported by the broadband router. The router must also support UPnP™.

• 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.

Enable/Disable - When enabled, the video encoder attempts to configure port mapping in a NAT router on your network,

using UPnP™. Note that UPnP™ must be enabled in the video encoder (see System Options > Network > UPnP).

Use manually selected NAT router - Select this option to manually select a NAT router and enter the IP address for the

router in the field provided.

If a router is not manually specified, the video encoder automatically searches for NAT routers on your network. If more than

one router is found, the default router is selected.

Alternative HTTP port - Select this option to manually define an external HTTP port. Enter the port number in the field

provided. If no port is entered here a port number is automatically selected when NAT traversal is enabled.
