I am using nftables with my own config files. I write the tables to /etc/sysconfig/nftables.conf so that nftables.service loads them at boot time.
firewalld.service is disabled
After reboot the nftables are loaded OK but the following rules are unexpectedly appended. The word "bridge" gives a clue.
I am not using virtual machines.
I have done: virsh net-autostart default --disable - no bridge devices are created (virbr0 etc).
What is adding to my rules and how can I disable it? It could be ebtables related but I have not found where.
Any ideas where to look?
Thanks
Alan
