"Use ip firewall" on Mikrotik 6

RouterOS General
1

Hello,

I have attach Ether 3(myPC) to Bridge_vlan122. Vlan122 is in Bridge_manage and Brdige_vlan122.
Ether1(Internet) is directly assigned to Bridge_manage.

Why, when I enable “use ip firewall” and “use ip firewall for VLAN” i dont have connection to Internet from PC ?
When it’s disabled Internet work OK.

Bridge->filter, bridge->nat, Firewall->NAT, Firewall->Filter rules = all empty.
On Mikrotik 5.7 this configuration work OK.

Thanks
Pawel R.
