6.5.14 Firewall

The firewall controls the travel of traffic between or within zones. You can also
configure the firewall to control traffic for NAT (DNAT) and policy routes (SNAT).
You can configure firewall rules based on schedules, specific users (or user
groups), source or destination addresses (or address groups) and services (or
service groups). Each of these objects must be configured in a different screen.
To-ZyWALL firewall rules control access to the ZyWALL. Configure to-ZyWALL
firewall rules for remote management. By default, the firewall only allows
management connections from the LAN, WLAN, or WAN zone.
