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.
Select this option to have this interface enforce links between specific IP
addresses and specific MAC addresses. This stops anyone else from manually
using a bound IP address on another device connected to this interface. Use
this to make use only the intended users get to use specific IP addresses.
Select this option to have the ZyWALL generate a log if a device connected to
this interface attempts to use an IP address that is bound to another device's
MAC address.
Click this to configure static IP addresses for the ZyWALL to assign to
computers connected to this interface. See
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.
Select this to turn on the connection check.
Select the method that the gateway allows.
Select icmp to have the ZyWALL regularly ping the gateway you specify to
make sure it is still available.
Select tcp to have the ZyWALL regularly perform a TCP handshake with the
gateway you specify to make sure it is still available.
Enter the number of seconds between connection check 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 use the default gateway for the connectivity check.
Select this to specify a domain name or IP address for the connectivity check.
Enter that domain name or IP address in the field next to it.
This field only displays when you set the Check Method to tcp. Specify the port
number to use for a TCP connectivity check.
Click OK to save your changes back to the ZyWALL.
Click Cancel to exit this screen without saving.
