The start and end IP addresses must belong to the same network segment as the IP
address of the LAN port of the device.
Subnet Mask
It specifies the subnet mask assigned by the DHCP server. The default value is
255.255.255.0.
Gateway Address
It specifies the default gateway IP address assigned by the DHCP server. Generally,
it is the IP address of the LAN port of the egress router. The default value is
192.168.0.254.
A client can access a server or host not in the local network segment only through
a gateway.
Primary DNS Server
It specifies the primary DNS server IP address assigned by the DHCP server. The
default value is 8.8.8.8.
To enable clients to access the internet, set this parameter to a correct DNS server
IP address or DNS proxy IP address.
Secondary DNS Server
It specifies the secondary DNS server IP address assigned by the DHCP server. This
parameter is optional. The default value is 8.8.4.4.
Lease Time
It specifies the validity period of an IP address assigned by the DHCP server to a
client.
When half of the lease time has elapsed, the client sends a DHCP request to the
DHCP server to renew the lease time. If the request succeeds, the lease time is
extended according to the request. Otherwise, the client sends the request again
when 7/8 of the lease time has elapsed. If the request succeeds, the lease time is
extended according to the request. Otherwise, the client must request an IP
address from the DHCP server after the lease time expires.
It is recommended that you retain the default value 1 day.
