LABEL DESCRIPTION
Gateway This field is enabled if you select Use Fixed IP Address.
Enter the IP address of the gateway. The Zyxel Device sends packets to the gateway when
it does not know how to route the packet to its destination. The gateway should be on the

Metric Enter the priority of the gateway (the ISP) on this interface. The Zyxel Device 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 Zyxel Device uses the one that was configured
first.
IPv6 Address These IP address fields configure an IPv6 IP address on the interface itself.
