You can also configure firewall and content filtering on the ZyXEL Device for
secure Internet access. When the firewall is on, all incoming traffic from the
Internet to your network is blocked 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.
Use content filtering to block access to specific web sites, with URL's containing
keywords that you specify. You can define time periods and days during which
content filtering is enabled and include or exclude particular computers on your
network from content filtering. For example, you could block access to certain web
sites for the kids.
Use QoS to efficiently manage traffic on your network by giving priority to certain
types of traffic and/or to particular computers. For example, you could make sure
that the ZyXEL Device gives voice over Internet calls high priority, and/or limit
bandwidth devoted to the boss's excessive file downloading.
