Address

Select this if you want to specify the IP address, subnet mask, and gateway

Enter the IP address for this interface.

Subnet Mask

This field is enabled if you select Use Fixed IP Address.

mask indicates what part of the IP address is the same for all computers in the 

network.

This field is enabled if you select Use Fixed IP Address.
Enter the IP address of the gateway. The ZyWALL sends packets to the 

gateway when it does not know how to route the packet to its destination. The 

gateway should be on the same network as the interface.

Enter the priority of the gateway (if any) on this interface. The ZyWALL decides 

which gateway to use based on this priority. The lower the number, the higher 

the priority. If two or more gateways have the same priority, the ZyWALL uses 

the one that was configured first.
