ZyWALL USG 50-H User's Guide
DESCRIPTION
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.
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.
Click this to associate a MAC address to a specific IP address.
Click this to have the ZyWALL record instances when associated IP address
and MAC addresses do not match.
Click this if you want the ZyWALL to assign static IP addresses to computers.
The Static DHCP screen appears.
Figure 162 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.
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.
Select this to enable the ping check.
Enter the number of seconds between ping attempts.
Enter the number of seconds to wait for a response before the attempt is a
failure.
Enter the number of consecutive failures before the ZyWALL stops routing
through the gateway.
Select this to ping the default gateway.
Select this to ping a specified domain name or IP address. Enter that domain
name or IP address in the field next to it.
Click OK to save your changes back to the ZyWALL.
Click Cancel to exit this screen without saving.
