10.14  Auxiliary Interface Screen
Use the auxiliary interface as a backup WAN interface or a way to access the ZyWALL for 
remote management. 
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.
Check Timeout
Enter the number of seconds to wait for a response before the attempt is a 
failure.
Check Fail 
Tolerance

through the gateway.

name or IP address in the field next to it.

Click OK to save your changes back to the ZyWALL.
