I have been thinking about nftables for our use cases. iptables is (slowly)
on its way out. firewalld does provide some abstraction from this, in that
firewalld could provide an interface to translate from iptables to nftables
without application changes. But, I am concerned that firewalld is not
sophisticated enough to meet requirements, and I am hesitant to really
invest in it if it is too simple for requirements.
Just some food for thought I had to offer...
