●DHCP vendor class ID:Exchanges vendor class ID by clients and servers to
convey particular configuration or other identification information about a client.
Default isHT8XX.

Use PPPoE Set the PPPoE account settings. If selected, ATA attempt to establish a PPPoE
session if any of the PPPoE fields is set.
●PPPoE account ID:Defines the PPPoE username. Necessary if ISP requires you
to use a PPPoE (Point to Point Protocol over Ethernet) connection.
●PPPoE password:Specifies the PPPoE account password.
●PPPoE Service Name:Defines PPPoE service name. If your ISP uses a service
name for the PPPoE connection, enter the service name here. This field is
optional. Default is blank.
Preferred DNS server Specifies preferred DNS server to use when DHCP or PPPoE are set.
Statically configured as IP address Configure IP address, subnet Mask, default router IP address, 1stpreferred DNS
server, 2ndpreferred DNS server. These fields are set to zero by default.
IPv6 Address
Allows users to configure the appropriate network settings on the HT80x to obtain
IPv6 address. Users could select “DHCP”, “Static IP”. By default, it is set to “DHCP”.
●DHCP mode:all the field values for the static IP mode are not used (even though
they are still saved in the flash memory.) The HT801/HT802 acquires its IP
address from the first DHCP server it discovers from the LAN it is connected.
●Static IP mode:configure IP address, 1stand 2ndDNS server, preferred DNS
server. These fields are set to zero by default.
●Full Static: When enabling the option full static, users need to specify the Static
IPv6 and the IPv6 Prefix length.
●Prefix Static: When enabling the option prefix static, users need to specify the
