An old problem I was involved in fixing is still rampant on 8.5 while fixed on Centos and RHEL The problem can be described here: [virtual machines - Port forward on CentOS 8 to VM with firewalld not working - Server Fault](https://serverfault.com/questions/1005400/port-forward-on-centos-8-to-vm-with-firewalld-not-working) There was an old workaround I had to utilize for the longest time: [firewall-cmd - add-forward-port don't work - Super User](https://superuser.com/questions/1474254/firewall-cmd-add-forward-port-dont-work/1475915#1475915) I thought this was a KVM (libvirt) issue, but it’s not existent on Centos8 or RHEL8 ---

One can see the entire ruleset with: `sudo nft list ruleset` ---
