disabled by default. The total bandwidth can be set as: 128K, 256K, 512K, 1M, 2M,
3M, 4M, 5M, 10M or 15M.
The primary function of this setting is to limit the download bandwidth for the device
internal system, signaling and NATed traffic. Example: if 128 is configured, there will
be at least 128kbps limited for internal system, signaling and NATed traffic. Voice or
RTP stream will never be limited.
When set to "Yes", the HT812/HT814 acts as an UPnP gateway for your UPnP enabled

addresses to internal network. Connect the WAN port to ADSL/Cable modem or any
other equipment that provides access to public Internet
LAN DHCP Base IP Base IP Address for a LAN port. Default factory setting is 192.168.2.1. Note: When the
device detects WAN IP is conflicting with LAN IP, the LAN base IP address will be
changed based on the network mask -- the effective subnet will be increased by 1.
For example; 192.168.2.1 will be changed to 192.168.3.1 if net mask is 255.255.255.0.
Then the device will reboot
LAN DHCP Start IP
Default value is 100. The last segment of IP address assigned to the HT812/HT814 in
the LAN Network.
Default configuration assigns IP address (to local network devices) starting from
192.168.2.100.
LAN DHCP End IP
Default value is 199. This parameter allows a user to limit the number of local network
devices connected to the internal router.
Default configuration assigns IP address (to devices connected to the LAN port) in a
range from 192.168.2.100 up to 192.168.2.199.
LAN Subnet Mask
Sets the LAN subnet mask.
Default value is 255.255.255.0
