Axis Communications 216FD/FD-V - Manual (Page 39)

39 AXIS 216FD/FD-V - System Options
Use NAT traversal when your AXIS 216FD/FD-V 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 will be
forwarded to the camera.

ISP
Notes:
• For NAT traversal to work, this must also 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 AXIS 216FD/FD-V will 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 AXIS 216FD/FD-V will automatically search for
NAT routers on your network. If more than one router is found, the default router will be
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 will
automatically be 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 e.g. 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 will automatically be
selected.
• When the port is selected automatically it will be displayed in this field. This can be changed by entering a
new port number and clicking Save.
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.
