through the Ethernet port or WiFi would obtain a dynamic IP address from CPE.
Enable DHCP Server: enable/disable DHCP server
DHCP Starting IP Address: The starting IP address assigned by DHCP server.
DHCP Ending IP Address: The ending IP address assigned by DHCP server.
Notice that WiFi and Ethernet share the same DHCP server, the range of IP
addresses should not be narrow.
Otherwise, clients cannot get LAN IP
addresses.
From ISP: When the checkbox is ticked, clients set CPE as DNS server, but CPE will only act as a “DNS
relay”.
If users want to know DNS Servers obtained from ISP, It can be found in
“Network > Status > WAN Information > DNS Server”
DNS 1/ DNS2 / DNS3: If the checkbox “From ISP” is not ticked, users can designate the DNS server for
DHCP clients. Two pictures below are captured from CPE and a PC in LAN, DNS fields are “1.1.1.1”,
“2.2.2.2” and “3.3.3.3”. Clients’ DNS request will be directly sent to the first operative server in the
order of primary, secondary and tertiary DNS.
Network > DHCP Server> not From ISP
“1.1.1.1”, “2.2.2.2” and “3.3.3.3” are examples.
DHCP Lease Time: The life time of the IP assigned by DHCP server( range: 2 minutes-365days)
Lease Reservation Table: This table records the mapping of MAC and IP addresses. Clients with the
specific MAC address in the table would get the corresponding IP address. Click “Add +” button to
add a new mapping, clicking “Delete” icon ( ) to delete it. To enable the mapping, users have to
tick the “Enable” checkbox.
An example is illustrated below. If a client with MAC Address “11:22:33:44:55:66”requests IP, DHCP
server will assign IP “192.168.15.123” and the host name “Example” to it.
