Subnet Mask A mask used to determine to what subnet an IP address be-
longs. An example of a subnet mask value is 255.255.0.0.
Lease Time In Minutes Each device will be assigned an IP address by
the DHCP server for a this amount of time, when it connects to the network.
When the lease expires the server will determine if the computer has discon-
nected from the network. If it has, the server may reassign this IP address to a
newly-connected computer. This feature ensures that IP addresses that are not
in use will become available for other computers on the network.
Provide Host Name If Not Specified by Client If the DHCP client does
not have a host name, the gateway will automatically assign one for him.
Click 'OK' to save the settings.

 DHCP Relay – Your gateway can act as a DHCP relay in case you would like
to dynamically assign IP addresses from a DHCP server other than your gate-
way's DHCP server. Note that when selecting this option you must also change
Watson's WAN to work in routing mode. For more information, refer to Section
8.6.2.2.
After selecting 'DHCP Relay' from the drop down menu, a 'New IP Address' link
will appear:
