Since upgrade to Router OS 6.47.4 from 6.43.2, i'm not able to create switch rules and switch vlans with Winbox 3.27. (RB3011UiAS).
I did upgrade to from Winbox 3.18 to Wonbox 3.27 at the same time.
The rules or vlans are added but appear colored in red inside Winbox. If i use Winbox 3.18, then adding rules work again.
If i try to add it through the console it's working.
And i suspect that some rules are not working correctly anymore since the upgrade as i have now some IPv4 leaking on IPv6 interfaces. This leaking was filtered here before.
I'm not sure that this last problem does come from the switch filter nevertheless, because this traffic should be catched before in the bridge filter. but it is not.
