DESCRIPTION
Specify the IP addresses up to three DNS servers for the DHCP clients
to use. Use one of the following ways to specify these IP addresses.
Custom Defined - enter a static IP address.
From ISP - select the DNS server that another interface received
from its DHCP server.
ZyWALL - the DHCP clients use the IP address of this interface and
the ZyWALL works as a DNS relay.
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 Edit static DHCP table to configure static IP addresses for the
ZyWALL to assign to computers connected to this interface.
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.
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.
