How does UPnP

work?
UPnP
TM
networking technology provides automatic IP configuration and dynamic discovery
of devices added to a network. Services and capabilities offered by networked devices,
such as printing and file sharing, are available among each other without bothersome
network configuration. In the case of Network Cameras, you will see Network Camera
shortcuts at My Network Places.
Enabling UPnP port forwarding allows the Network Camera to open secondary HTTP

port on the gateway, not HTTP port 80, meaning that you have to add the secondary
HTTP port number behind the Network Camera's public address in order to access the
Network Camera from the Internet. For example, when the HTTP port is set to 80 and the
secondary HTTP port is set to 8080, refer to the list below for the Network Camera's IP
address.
From the Internet
In a LAN
http://203.67.124.123 : 8080
http://192.168.4.160 or
http://192.168.4.160 : 8080
If the PPPoE settings are incorrectly configured or the Internet access is not working,

restore the Network Camera to factory default; refer to Restore on page 67 for details.
After the Network Camera is reset to factory default, it is accessible in a LAN.
HTTP
Authentication:
Depending on your network security requirements, the Network
Camera provides two types of security settings for a HTTP transaction: basic and
digest. If basic authentication is selected, the password is sent in plain text format;
there can be potential risks of being intercepted. If digest authentication is selected,
user credentials are encrypted in MD5 algorithm and thus provide better protection
against unauthorized accesses.
HTTP port or Secondary HTTP port:
By default, the HTTP port is set to 80 and
the secondary HTTP port is set to 8080. Also, they can be assigned with another
port number between 1025 and 65535. If the ports are incorrectly assigned, the
following warning messages are displayed:
