IP Version: There are two options: IPv4 and IPv6. Right now, system supports these two IPaddress format and you can access via them. MAC address: The host in the LAN can get a unique MAC address.

Usually it includes an organization of multiple-level. Default gateway: Here you can input the default gateway. Please note system needs tocheck the validity of all IPv6 addresses. The IP address and the default gateway shallbe in the same IP section. That is to say, the specified length of the subnet prefix shallhave the same string. DHCP: It is to auto search IP. When enable DHCP function, you can not modify IP/Subnetmask /Gateway. These values are from DHCP function. If you have not enabled DHCPfunction, IP/Subnet mask/Gateway display as zero. You need to disable DHCP function toview current IP information. Besides, when PPPoE is operating, you can not modifyIP/Subnet mask /Gateway. TCP port: Default value is 37777. You can change if necessary. UDP port: Default value is 37778. You can change if necessary. HTTP port: Default value is 80. RTSP port: Default value is 554.Important: System needs to reboot after you changed and saved any setup of the abovefour ports. Please make sure the port values here do not conflict.
