Note: If both blacklist and whitelist are not empty, the blacklist is processed first, followed by  

the whitelist.  

Whitelist for WAN Side  

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”.  

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.

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”.  

IPv4 Address  

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.  

Dynamically assigned via DHCP  

● 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.  

Use PPPoE  

● 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.  

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.  

Statically configured as IP 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.

These fields are set to zero by default.

the IPv6 Prefix length.  

● Prefix Static: When enabling the option prefix static, users need to specify the IPv6 Prefix  

(64 bits).
