Axis Communications 231D+/232D+ - Manual (Page 43)

43 AXIS 231D+/232D+ - System Options
HTTP
The default HTTP port number (80) can be changed to any port within the range
1024-65535. This is useful for e.g. simple port mapping.
HTTPS
The default HTTPS port number (443) can be changed to any port within the range
1024-65535. HTTPS is used to provide encrypted web browsing.
NAT Traversal
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 231D+/232D+ 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 231D+/232D+ 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 231D+/232D+ will automatically search for
NAT routers on your network. If more than one router is found, the default router will be
selected.
