AXIS 214 PTZ 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 214 PTZ 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. 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 214 PTZ 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 214 PTZ 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 number is entered here, a number will automatically be selected when NAT traversal is enabled. Notes: • An alternative HTTP port number 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 number that is already in use, another available port number will automatically be selected. • When the port number 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 the AXIS 214 PTZ 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. 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), 100BaseTX (Half/Full Duplex). Maximum bandwidth - Specify, in Mbit/s or Kbit/s, the maximum bandwidth that the AXIS 214 PTZ is allowed to use on your network. This is a useful function when connecting the AXIS 214 PTZ to busy or heavily loaded networks. The default setting is Unlimited. For more information, please refer to the online help. Network - SOCKS SOCKS is a networking proxy protocol. The AXIS 214 PTZ 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 AXIS 214 PTZ is located on a local network behind a firewall, but notifications, uploads, and alarms need to be sent to a destination outside the local network (e.g. to the Internet).

AXIS 214 PTZ
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 214 PTZ 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.
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 214 PTZ 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 214 PTZ 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 number is entered here, a number will automatically be selected when NAT
traversal is enabled.
Notes:
•
An alternative HTTP port number 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 number that is already in use, another available port number will
automatically be selected.
•
When the port number 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 the AXIS 214 PTZ 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. Enter the RTSP port number to
use. The default setting is 554.
Network Traffic

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), 100BaseTX (Half/Full Duplex).
Maximum bandwidth
- Specify, in Mbit/s or Kbit/s, the maximum bandwidth that the AXIS 214 PTZ is
allowed to use on your network. This is a useful function when connecting the AXIS 214 PTZ to busy or
heavily loaded networks. The default setting is

networks on the other side of a firewall/proxy server. This functionality is useful if the AXIS 214 PTZ is
