All documentation rights reserved. 435.6.5 NetworkThis Menu section allows you to input network information (see Figure 5-31).Figure 5-31 IP Version: ‘IPv4 and IPv6’ are the two options to choose from. Right now, the system supportsthese two IP address formats and you can access the network through them. MAC address: The host in the LAN can acquire a unique MAC address. It is to allow you to gainaccess in to the LAN (read-only). IP address: Here you can use the up/down buttons () or input the correspondingnumber to input the IP address. Then you can set the corresponding subnet mask to get thedefault gateway address. Subnet prefix: The input value ranges from 0 to 128. This is to mark a specified networkMAC address. Usually it includes an organisation made up of multiple-levels. Default gateway: Here you can input the default gateway.Note: system needs to check the validity of all IPv6 addresses. The IP address and thedefault gateway shall be in the same IP section, which means that the specified lengthof the subnet prefix shall have the same string. DHCP: This will automatically search for the IP. When you enable the DHCP function, youcannot modify IP/Subnet mask /Gateway. These values are from the DHCP function. If youhave not enabled DHCP function, IP/Subnet mask/Gateway displays this as zero. You needto disable DHCP function to view current IP information. Although, whilst the PPPoE isoperating, you cannot modify IP/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.
