Telrad CPE12000 Series User Manual page 61

CPE has a built-in DHCP server to manage the distribution of IP addresses. A device connected to
CPE 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.
From ISP: When the checkbox is ticked, clients set CPE as DNS server, but CPE will only act as a
"DNS relay".
Primary/Secondary/Tertiary DNS: 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.
