and I noticed that the last update did add and ebtables.
Code:
Selecting previously unselected package ebtables.^M
Preparing to unpack .../24-ebtables_2.0.10.4-3.5+b1_amd64.deb ...^M
I was running iptables.service and all the rules pve generated and I added myself are in there `iptables -L`.
Now the iptables.service is not running anymore but the ebtables.service. Unfortunately the rules are empty and no connections are dropped anymore.

If I add new rules in the WebUI the change is reflected in /etc/pve/nodes/<hostname>/host.fw, but not in ebtables nor iptables.

Another side effect, I recognized is that NAT containers are not working anymore, is this intended?
I would be ok with a change to ebtables, if the rules I specified in pve would still work, how can I fix this?

Thanks
Conrad
 
same problem here.

I was importing rules with this command:
ebtables-restore < /root/scripts/ebtables.txt

Now, after a few seconds, my rules disappears. No more filtering between my CTs :(
 
@conrad784, ebtables runs in addition to iptables, if your iptables are empty there must be some other issue, you should check your rules and logs.
@arteta, that's a different issue, you already had ebtables rules which now get replaced - please open a feature request on our bugzilla
 
One more reason to switch finally to single common nftables, instead of {ip,ip6,arp,eb}tables.
