Code:
# systemctl status firewalld

   Loaded: loaded (/usr/lib64/systemd/system/firewalld.service; enabled; vendor preset: disabled)

mei 11 09:34:28 <hostname> /firewalld[472]: 2016-05-11 09:34:28 ERROR: ebtables not usable, disabling ethernet bridge firewall.

The firewall itself seems to function. Nevertheless, how can I fix this error (message)? (There is no further information in the logs. A google search turns up other, real issues in which the logs also contain this message.)

I have ebtables installed:
Code:
# eix -I ebtables
[I] net-firewall/ebtables
     Available versions:  2.0.10.4 ~2.0.10.4-r1 {+perl static}
     Installed versions:  2.0.10.4(22:15:51 01-05-16)(-static)
     Homepage:            http://ebtables.sourceforge.net/
     Description:         Utility that enables basic Ethernet frame filtering on a Linux bridge, MAC NAT and brouting

Iptables is the firewall...... only
ebtables and iproute2 is what?? Routing, here you need also some rules.....
listen, for someone new in firewalling it can be dangerous with just one wrong line and setting.. what are you planing in detail?

Hmm, it seems I don't have this warning anymore. I'll mark this as solved.

I'm having the same issue right now on Gentoo with kernel 4.9.76-r1.

I wonder if it has something to do with kernel configuration.

Code:
kernel: Ebtables v2.0 unregistered

This issue has been marked as solved, so if you want to get assistance, you better start a new thread.
