Router User's Guide
4. In End IP Range, enter the ending IP address of the range of addresses from which the DHCP server
will lease to requesting DHCP clients.
This range definition should consider the following address restrictions:
• The range of IP addresses may extend over only one IP subnet.
• The maximum size of the address pool that may be managed by the DHCP server is 64.
Therefore, the range of addresses must not exceed 64.
• The range of IP addresses should not include any IP address maintained internally by your
SpeedStream device for other purposes. This includes the device's LAN-side static IP address, as
well as the Default Router IP address, Primary or Secondary DNS IP addresses, and Primary or
Secondary Relay IP addresses
• Commonly used non-Internet routed IP address ranges include:
10.0.0.0
172.16.0.0
192.168.0.0
5. In IP Netmask, enter the IP subnet mask that corresponds to the range of IP addresses defined
above.
6. In Default Gateway, do one of the following:
• Enter the IP address of a default gateway, or router, to be provided to DHCP clients.
• Click Self to specify that the SpeedStream Router is to be used as the default gateway.
7. In DNS Server (primary), do one of the following:
• Enter IP address of the primary Domain Name System (DNS) server to be provided to DHCP
clients. A DNS server may be used by clients to resolve domain names to IP addresses.
• Click Use WAN to specify that the address of the DNS server provided by your ISP is provided to
DHCP clients on the LAN.
8. In Domain Name, optionally enter the DNS domain name for the DHCP server resident on your
SpeedStream device. This value must be entered as an alpha-numeric string.
9. In Lease Time, do one of the following:
• Enter the period of time an IP addresses leased from the DHCP server is valid. 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 the client's connection no longer exists. The server will release the IP address
assigned to the client and return the address back to the pool of available addresses. (If you select
this option, you must specify a DNS Server.)
• Click Infinite Time:
Leaves the lease time open-ended, preventing the server from releasing the IP address.
10. Click Save Settings.
