AXIS 207/207W - System Options
Use NAT traversal when your AXIS 207/207W 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 207/207W 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, the AXIS 207/207W 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 e.g. 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.
