AXIS P1311 - 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 - w

hen 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 o

ption 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 network cameras automatically sea

rch for NAT routers on your network. If more than

one router is found, the default router is selected.

Alternative HTTP port - Select th

is 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 tr

aversal 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 H.264/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 and H.264 video streams will not be

available if this service is not enabled.

SOCKS

SOCKS is a networking proxy protocol. The Axis network camera can be configured to use a SOCKS server to reach networks

on the other side of a firewall/proxy server. This functionality is useful if the network camera is located on a local network

behind a firewall, and notifications, uploads, alarms, and such need to be sent to a destination outside the local network (such

as the Internet). See the online help for more information.
