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 web sites with URLs 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.
