Addr select DHCP, or Static IP. By default, it is set to DHCP.
ess 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 ATA 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 IPv6 Prefix (64 bits).

NAT/DHCP Server Information & Configuration
Controls whether the device is working inNAT router, Bridge, or WAN Only mode.
NAT Router: In this mode, the WAN port acts as a DHCP client. LAN port is used as DHCP Base IP; devices
Devi connected behind the LAN port will be assigned an IP from HT813 DHCP Server.
ce Bridge: In this mode, the WAN port acts as a DHCP client and pass-through to the LAN port; devices connected
Mod behind the LAN port will get an IP from your network DHCP server (same as the WAN port).
e WAN Only: In this mode, only the WAN port is active. LAN port is not used.
The default mode is NAT Router.
Save the setting and reboot prior to configuring the HT813.

Uplin Specifies the maximum uplink bandwidth permitted by the device. This function is disabled by default. The total
k bandwidth can be set as: 128K, 256K, 512K, 1M, 2M, 3M, 4M, 5M, 10M or 15M. The primary function of this setting
Band is to limit the uplink bandwidth for the device internal system, signaling and NATed traffic. Example: When 512k is
