NB3000-Line-Hd User Manual 4.2
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.
Figure 5.27.: Inbound NAPT
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.
