Netopia 3300 - Manual (Page 211)

IP Setup 7-19
• The DHCP Next-Server field allows you to enter the IP address of the next ser ver in the boot process,
which is typically a Trivial File Transfer Protocol (TFTP) ser ver.
• The default DHCP Lease time is one hour. This may be unnecessarily brief in your network environment.
Consequently, the DHCP lease time is configurable. The DHCP Lease Time (Hours) setting allows you to
modify the gateway’s default lease time of one hour. You can enter any number up to and including 168
hours (one week) for the DHCP lease.
Note: About DHCP Auto-configuration:
Cer tain model gateways will allow the IP Address Ser ver to auto-configure when the gateway is configured with
a new IP Address and Subnet Mask. This applies according to the following guidelines:
• If you configure the gateway with a 24 bit Subnet Mask (Class C), the gateway will continue ser ving from
100-199, with the new IP Address.
• If you configure the gateway with a subnet smaller than a Class C subnet, the gateway will ser ve all available
addresses.
• If you explicitly configure the DHCP pool, auto-configuration of the DHCP pool is suppressed.
• If you configure the gateway manually and you would like the gateway to auto-configure DHCP, you must
explicitly set the IP Address and Subnet Mask to 0.0.0.0 and reboot.
If you have configured multiple Ethernet IP subnets, the appearance of the IP Address Ser ving screen is altered
slightly:
Three menu items are hidden, and Configure Address Pools... appears instead. If you select Configure
Address Pools... you will be taken to the IP Address Pools screen that allows you to configure an address
ser ving pool for each of the configured Ethernet IP subnets. See
“IP Address Pools” on page 7-20 .
