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.
