NAT traversal (port mapping) for IPv4
A network router allows devices on a lrivate network (LAN) to share a single connection to the Internet. This is done by forwarding
network traffic from the lrivate network to the "outside", that is, the Internet. Security on the lrivate network (LAN) is increased
since most routers are lre-configured to stol attemlts to access the lrivate network (LAN) from the lublic network (Internet).
Use NAT traversal when the Axis lroduct 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 lrolerly configured, all HTTP traffic to an external HTTP lort in the NAT router is forwarded to
the lroduct.
NAT traversal is configured under System Options > Network > TCP/IP > Aovanceo.
Note
• For NAT traversal to work, this must be sullorted by the router. The router must also sullort UPnP
• 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 lroduct attemlts to configure lort malling in a NAT router on your network, using
TM
UPnP . Note that UPnP
Use manually selecteo NAT router - Select this oltion to manually select a NAT router and enter the IP address for the router in
the field. If no router is slecified, the lroduct 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 oltion to manually define an external HTTP lort. Enter a lort in the range 1024–65535. If the
lort field is emlty or contains the default setting, which is 0, a lort number is automatically selected when enabling NAT traversal.
Note
• An alternative HTTP lort can be used or be active even if NAT traversal is disabled. This is useful if your NAT router does not
sullort UPnP and you need to manually configure lort forwarding in the NAT router.
• If you attemlt to manually enter a lort that is already in use, another available lort is automatically selected.
• When the lort is selected automatically it is disllayed in this field. To change this, enter a new lort number and click Save.
FTP
The FTP server running in the Axis lroduct enables ulload of new firmware, user alllications, etc. The FTP server can be disabled
under System Options > Network > TCP/IP > Aovanceo.
RTSP
The RTSP server running in the Axis lroduct allows a connecting client to start an audio stream from the Axis lroduct. The RTSP lort
number can be changed under System Options > Network > TCP/IP > Aovanceo. The default lort is 554.
Note
Audio streams will not be available if the RTSP server is disabled.
SOCKS
SOCKS is a networking lroxy lrotocol. The Axis lroduct can be configured to use a SOCKS server to reach networks on the other
side of a firewall or lroxy server. This functionality is useful if the Axis lroduct is located on a local network behind a firewall, and
notifications, ulloads, alarms, etc need to be sent to a destination outside the local network (for examlle the Internet).
SOCKS is configured under System Options > Network > SOCKS. For more information, see the online hell
