7.2.2.1 Configuration Server Contacts IP-852 Device
In this scenario, the IP-852 device needs the following parameters set in order for the
configuration server to contact the device. The remaining parameters are retrieved from the
configuration server.
IP address/netmask/gateway (either via DHCP or manual entry), see Section 6.2.4
Auto-NAT or manual NAT address if used behind a firewall/NAT router, see Section
6.2.10
MD5 secret if authentication is required, see Section 6.2.10
If multiple CEA-852 devices behind one NAT router are added, the Auto-NAT setting in
the L-IP is recommended to be used with the CEA-852 configuration server.
7.2.2.2 IP-852 Device Contacts Configuration Server
In this scenario, the IP-852 device needs the following parameters set in order to contact the
configuration server. The remaining parameters are retrieved from the configuration server.
IP address/netmask/gateway (either via DHCP or manual entry), see Section 6.2.4
Auto-NAT or manual NAT address if used behind a firewall/NAT router, see Section
6.2.10
MD5 secret if authentication is required, see Section 6.2.10
Configuration server IP address and port number, see Section 6.2.10
If the “Auto member” feature is enabled in the configuration server, the CEA-852 device
can add itself to the IP-852 channel without explicitly adding the device at the configuration
server. Note, that enabling auto member is a potential security hole since any device can
add itself to the IP-852 channel.
7.2.2.3 Using the Built-In Configuration Server
For security purposes, the configuration server contacts each CEA-852 device on the IP-852
channel. Therefore, one must enter a list of all channel members in the CEA-852
