Hello all... (again...) Well, as I trudge down my upgrade to rhel 7, I'm now trying to fully understand firewalld. The bit which has me a bit confused with the documentation is the zone bit. rhel 7 comes with a bunch of predefined zones. What I'm thinking is that each one of these zones is a particular firewall setup and then you assign a network interface to a zone. So if I have 3 NIC cards on my computer, running on 3 different networks, by assigning each of the NIC cards to different zones gives each NIC card that particular firewall configuration as defined by the zone. So if I want to setup my own configuration for one of my NIC cards, which is completely unique, I then have to create a new zone, and assign the NIC card to that zone. What I can't do (I believe) is assign a NIC card to a zone, then and and extra port which would be just specific to that NIC card. Correct? Thanks in advance. Cheers. Steve.
