For static IP mode, you usually receive a fixed public IP address or a public subnet, namely
multiple public IP addresses from your DSL or Cable ISP service providers. In most cases, a
Cable service provider will offer a fixed public IP, while a DSL service provider will offer a
public subnet. If you have a public subnet, you could assign an IP address or many IP
address to the WAN interface.
To use Static or Dynamic IP as the accessing protocol of the internet, please choose
Internet Access from WAN menu. Then, select Static or Dynamic IP mode for WAN2.
