Consequently, the DHCP lease time is configurable. The DHCP Lease Time (Hours) setting allows you to 
modify the router’s default lease time of one hour. You can enter any number up to and including 168 hours 
(one week) for the DHCP lease.

About DHCP Auto-configuration:

Beginning with Firmware Version 5.3.4, routers whose model number ends in “-T” will allow the IP Address 
Ser ver to auto-configure when the router is configured with a new IP Address and Subnet Mask. This applies 
according to the following guidelines:
• If you configure the router with a 24 bit Subnet Mask (Class C), the router will continue ser ving from 100-199, 
   with the new IP Address.
• If you configure the router with a subnet smaller than a Class C subnet, the router 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 router manually and you would like the router 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
