Axis Communications AXIS 233D - Manual (Page 45)

45 AXIS 233D - System Options
Link-Local IPv4 Address
This is enabled by default and assigns the AXIS 233D an additional IP address for use with
UPnP
™
. The AXIS 233D can have both a Link-Local IP and a static/DHCP-supplied IP
address at the same time - these will not affect each other.
HTTP
The default HTTP port number (80) can be changed to any port within the range 1 - 65535.
This is useful for e.g. simple port mapping.
HTTPS
If applicable, enter the HTTPS port the AXIS 233D will use. The default setting (443) can be
changed to any port within the range 1024-65535. HTTPS is used to provide encrypted
web browsing.
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 233D 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.
