You can also configure Firewall on the Zyxel Device for secure Internet access. When the Firewall is on,
all incoming traffic from the Internet to your network is blocked by default unless it is initiated from your
network. This means that probes from the outside to your network are not allowed, but you can safely
browse the Internet and download files.
Connect the WAN port to the broadband modem or router. This way, you can access the Internet
through an Ethernet connection and use the QoS, Firewall and parental control functions on the Zyxel
Device.
