Users can configure the whitelist for WAN Side to be used for remote management.
Multiple IPs are supported and need to be separated by "space".
Example: 192.168.5.222 192.168.5.223 192.168.7.0/24
Note: If both blacklist and whitelist are not empty, the blacklist is processed first, followed by
the whitelist.
Users can configure the blacklist for WAN Side to ban WAN side web access.
Multiple IPs are supported and need to be separated by "space".

Allows users to configure the appropriate network settings on the HT80x to obtain IPv4
address. Users could select "DHCP", "Static IP" or "PPPoE". By default, it is set to "DHCP".
All the field values for the static IP mode are not used (even though they are still saved in the
flash memory.) The HT801/802 acquires its IP address from the first DHCP server it
discovers from the LAN it is connected.
● DHCP hostname: Specifies the name of the client. The name may or may not be qualified
with the local domain name. This field is optional but may be required by ISP.
● DHCP domain name: Specifies the domain name that client should use when resolving
hostname via the Domain Name System.
● 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.
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.
Specifies preferred DNS server to use when DHCP or PPPoE are set.
