AXIS M3106-L Network Camera
System Options
NAT traversal (port mapping) for IPv4
A network 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”, that is, the Internet. Security on the private network (LAN) is increased
since most routers are pre-configured to stop attempts to access the private network (LAN) from the public network (Internet).
Use
NAT traversal
when the Axis product 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 is forwarded to
the product.
NAT traversal is configured under
System Options > Network > TCP/IP > Advanced
.
Note
• For NAT traversal to work, this must be supported by the router. The router must also support UPnP
TM
.
• In this context, router refers to any network routing device such as a NAT router, Network router, Internet Gateway,
Broadband router, Broadband sharing device, or a software such as a firewall.
Enable/Disable -
When enabled, the Axis product attempts to configure port mapping in a NAT router on your network, using UPnP
TM
.
Note that UPnP
TM
must be enabled in the product (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. If no router is specified, the product automatically searches 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 a port in the range 1024–65535. If the
port field is empty or contains the default setting, which is 0, a port number is automatically selected when enabling NAT traversal.
Note
• An alternative HTTP port can be used or 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 Axis product enables upload of new firmware, user applications, etc. The FTP server can be disabled
under
System Options > Network > TCP/IP > Advanced
.
Note
This FTP server has nothing to do with the product’s ability to transfer images via FTP to other locations and servers.
RTSP
The RTSP server running in the Axis product allows a connecting client to start an H.264 stream. The RTSP port number can be
changed under
System Options > Network > TCP/IP > Advanced
. The default port is 554.
Note
H.264 video streams will not be available if the RTSP server is disabled.
SOCKS
SOCKS is a networking proxy protocol. The Axis product can be configured to use a SOCKS server to reach networks on the other
side of a firewall or proxy server. This functionality is useful if the Axis product is located on a local network behind a firewall, and
notifications, uploads, alarms, etc need to be sent to a destination outside the local network (for example the Internet).
SOCKS is configured under
System Options > Network > SOCKS
. For more information, see the online help
