Forward Ports
(6)
The firewall supports “port forwarding”, which is commonly used
together with NAT zones (NAT = Network Address Translation, a.k.a.
“masquerading”). It allows traffic arriving at a certain port of an interface to
be forwarded to a certain port of another interface, e.g. of an “internal”
interface like a virtual container interface (“veth”), whose IP address is not
“visible” to the “outside world”.
Port forwarding settings are displayed in the
Forward Ports
table of the
zone.
