This section introduces port groups and then explains the screen for port groups.

Use port grouping to create port groups and to assign physical ports and port groups to 
Ethernet interfaces.

Edit static DHCP 
table

Click this if you want the ZyWALL to assign static IP addresses to computers. 
The Static DHCP screen appears.

Figure 126   Network > Interface > Ethernet > 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.
