Axis 212 PTZ-V User Manual page 35

NAT traversal (port mapping) - 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" i.e. the Internet. Security
on the private network (LAN) is increased since most broadband routers are pre-configured to stop any attempts to access the
private network (LAN) from the public network/Internet.
Use NAT traversal when your AXIS 212 PTZ/-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.
LAN (intranet)
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, AXIS 212 PTZ/-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).
AXIS Internet Dynamic DNS Service - Use this free service to assign a host name (user-friendly name) for easy access to your
camera. If the IP address of the camera or NAT router changes, the AXIS Internet Dynamic DNS Service will automatically be
updated with the new IP address.
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, AXIS 212 PTZ/-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 for example,
your NAT router does not support UPnP and you need to manually configure port forwarding in the NAT
router.
• If a manually selected port is already in use, another 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.
FTP - The FTP server running in AXIS 212 PTZ/-V enables the upload of for example, new firmware, user applications, etc.
Check the box to enable the service.
RTSP - The RTSP protocol allows a connecting client to start an MPEG-4 stream. Enter the RTSP port number to use. The
default setting is 554.
Network Traffic - The default connection setting is Auto-negotiate, which means that the correct speed is automatically
selected. If necessary, you can set the connection speed by selecting it from the drop-down list: 10BaseT (Half/Full Duplex), or
100BaseTX (Half/Full Duplex).
