NetModule NB3710 User Manual page 88

Parameter
Source netmask
NAPT Inbound Rules
Inbound rules can be used to modify the target section of IP packets and, for instance,
forward a service or port to an internal host. By doing so, you can expose that service
and make it available from the Internet. You may also establish 1:1 NAT mapping for
a single host using additional outbound rules.
Please note that the specified rules are processed by order, that means, traversing the
list from top to bottom until a matching rule is found. If there is no matching rule
found, the packet will pass as is.
