Description: Network Mask of the GW behind the Bridge (an empty mask will be denoted by 0.0.0.0)
What is fwNetIfNetmask?
The desc explicitly states this is the network mask of the gateway behind the bridge, and that an empty mask is denoted by 0.0.0.0. This field is specifically meaningful when fwNetIfFlags marks the interface as a Bridge (flag value 8); on that kind of interface, 0.0.0.0 simply means no gateway mask has been learned or configured yet behind the bridge. e.g. netmask = 255.255.255.0 for the network sitting behind a transparent bridge, telling the firewall the /24 it is bridging traffic for.
