Link-Local IPv4 Address
This is enabled by default and assigns the AXIS 210A/211A an additional IP address for
™
use with UPnP . The AXIS 210A/211A 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
1024-65535. This is useful for simple security 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 (port mapping) for IPv4
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 attempt to access the private network
(LAN) from the public network/Internet.
