Enable DHCP Server: Select to enable DHCP server.
Start and End IP Address: Specify the range of IP addresses assigned to DHCP
clients. The range of IP addresses must be on the same subnet as the LAN
interface of the Device, and cannot include the IP address of the LAN interface.
Subnet Mask: The subnet mask address assigned by the DHCP server to the
intranet computers automatically. This subnet mask must match the subnet mask
of the LAN interface.
Gateway IP: Specify the gateway IP address assigned by the DHCP server to the
intranet computers automatically. This gateway IP address must match the
gateway IP address of the LAN interface.
Lease Time: The leasing time for the network computers to obtain the IP address
assigned by the Device (Unit: Seconds).
Primary DNS Server: The primary DNS server IP address assigned by the DHCP
server to the Intranet computers automatically.
Secondary DNS Server: The secondary DNS server IP address assigned by the
DHCP server to the Intranet computers automatically.
Option 43: By modifying the variable length fields of option 43 attribute in the
DHCP protocol packets which is used to carry the IP address of AC, AP analyze
the AC address carried by option 43 to discover AC. The available options are
Disable, HEX Length, ASCII Length, and Customized.
AC Address: The IP address of AC.
Enable DNS Proxy: Select to enable DNS Proxy. When acting as a DNS proxy,
the Device listens for incoming DNS requests on the LAN interface, relays the
DNS requests to the current public network DNS servers, and replies as a DNS
resolver to the requesting LAN hosts.
ISP DNS Server 1 or ISP DNS Server 2: Specify the IP address of ISP's DNS
server that is available to a DHCP client.
Note:
1) If the DHCP Server is enabled, the LAN computer could obtain an IP address and
other TCP/IP parameters from the Device's built-in DHCP server after setting the
way of computer's getting IP address as "obtain an IP address automatically".
2) If the DNS proxy is enabled on the Device, in order to use DNS proxy service
normally, the LAN hosts' primary DNS server needs to be set same to the
Device's LAN IP address. Note: If the DHCP server is also enabled on the Device,
the Device will assign its LAN IP address as the primary DNS server address to
the LAN hosts automatically.
3) To ensure that the DNS proxy works well, you should at least specify the primary
