AXIS 216FD/FD-V - System Options

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 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.

Enable/Disable - when enabled, the network cameras attempt to configure port mapping in

a NAT router on your network, using UPnP™. Note that UPnP™ must be enabled in the

camera (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 n

etwork cameras automatically search 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.

Notes:

• An alternative HTTP port can be used/be active even if NAT traversal is disabled. This is useful if your NAT

router does not support UPnP and you need to manually configure port forwarding in the NAT router.

• If you attempt to manually enter a port that is already in use, another available port is automatically

selected.

• When the port is selected automatically it is displayed in this field. To change this enter a new port number

and click Save.

FTP - The FTP server running in the network cameras enables the upload of new firmware,

and user applications. Check the box to enable the service.

RTSP - The RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the

box to enable the server and enter the RTSP port number to use. The default setting is 554.

Note that MPEG-4 video streams will not be available if this service is not enabled.
