interfaces and VPN tunnels. The ZyWALL uses zones, not interfaces, in many
security settings, such as firewall rules and remote management.
Zones cannot overlap. Each interface and VPN tunnel can be assigned to at most
one zone. Virtual interfaces are automatically assigned to the same zone as the
interface on which they run. When you create a zone, the ZyWALL does not create
any firewall rules, assign an IDP profile, or configure remote management for the
new zone.

6.5.10 NAT

Use Network Address Translation (NAT) to make computers on a private network
behind the ZyWALL available outside the private network.
The ZyWALL only checks regular (through-ZyWALL) firewall rules for packets that
are redirected by NAT, it does not check the to-ZyWALL firewall rules.
