the ZyWALL use its permanent, pre-defined NAT address mapping rules.
Select
Full Feature

This lets the ZyWALL use the address mapping rules that you configure. This is the

configured. The first number shows how many address mapping rules are
configured on the ZyWALL. The second number shows the maximum number of
address mapping rules that can be configured on the ZyWALL.
