When you set DNS IP with one fixed Internet IP, NetDVR will send some information such as NetDVR name, NetDVR serial number, NetDVR current IP to that fixed
IP address. We call that fixed Internet IP as DNS IP. The DNS server with that fixed Internet IP can receive NetDVR information and used to resolve NetDVR dynamic
IP. This DNS is special software, not the normal domain name server.
Multicast IP:
It is one D-class IP address, among 224.0.0.0 --- 239.255.255.255.
If you do not use multicast function, please set it null.
Some routers prohibit multicast function in case of network storm.
Alarm Host IP and Port:
If you set this IP and port,
when alarm or exception happens, NetDVR will send information to that host IP.
The center with this IP can receive alarm and exception information from NetDVR.
NFS:
Network Access Storage.
NetDVR will regard network HDD as local HDD and
send the real time image to that network HDD.
NFS IP: The IP of that network storage server.
Dir: The directory name shared by that network storage server.
WebPort:
The port is for IE browser. The default value is 80. It can be modified.

NetDVR support PPPoE dial-up function.
