WINS Server
Type the IP address of the WINS (Windows Internet Naming Service) server that you
want to send to the DHCP clients. The WINS server keeps a mapping table of the
computer names on your network and the IP addresses that they are currently using.
Default Router If you set this interface to DHCP Server, you can select to use either the interface’s IP
address or another IP address as the default router. This default router will become the
DHCP clients’ default gateway.
To use another IP address as the default router, select Custom Defined and enter the
IP address.
Lease time Specify how long each computer can use the information (especially the IP address)
before it has to request the information again. Choices are:
infinite - select this if IP addresses never expire
days, hours, and minutes - select this to enter how long IP addresses are valid.

Description Enter a description to help identify this static DHCP entry. You can use alphanumeric
and
()+/:=?!*#@$_%-
characters, and it can be up to 60 characters long.
Connectivity Check The interface can regularly check the connection to the gateway you specified to make
sure it is still available. You specify how often the interface checks the connection, how
long to wait for a response before the attempt is a failure, and how many consecutive
failures are required before the ZyWALL stops routing to the gateway. The ZyWALL
resumes routing to the gateway the first time the gateway passes the connectivity
check.
