or Use WAN:
Specifies that the DNS server address received from the WAN-side DHCP server is to be provided to
DHCP clients on the LAN.
• Domain Name:
Specifies the DNS domain name for the DHCP server resident on your SpeedStream device. This
value must be entered as an alpha-numeric string. This parameter is optional.
• Lease Time:
IP addresses are leased from the DHCP server and are valid for a specified period of time, the lease
time. At the end of the lease period, the DHCP client will transmit a request to the server to extend the
lease, at which time the server will extend the lease period of the IP address assigned to the client. If
the lease period expires without the server receiving a request from the client to extend the lease, the
server will assume that the client's connection no longer exists, and the server will release the IP
address assigned to the client and return the address back to the pool of available addresses.
• or Infinite Time:
Leaves the lease time open-ended, preventing the server from releasing the IP address.
To specify the DHCP configuration settings:
The DHCP operating mode defaults to
Enable, and the system auto-generates the
current IP address range, IP netmask, and
