First WINS
Server, Second
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.
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.
Edit static DHCP
table
Click this if you want the ZyWALL to assign static IP addresses to computers.
The Static DHCP screen appears.
Figure 183 Network > Interface > Edit > Edit static DHCP table
The ZyWALL checks this table when it assigns IP addresses. If the computer’s
MAC address is in the table, the ZyWALL assigns the corresponding IP
address. Otherwise, the ZyWALL assigns the IP address dynamically using the
IP Pool Start Address and Pool Size.
Note: You must click OK in the Static DHCP screen and then
click OK in this screen to save your changes.
Ping Check The interface can regularly ping the gateway you specified to make sure it is still
available. You specify how often the interface pings the gateway, 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
acknowledges the ping.
Enable Select this to enable the ping check.
Check Period Enter the number of seconds between ping attempts.
