Security Group wont apply to VM

Hi,

I’ve had a couple of VMs and dummy VNETs. Then I created a new fw VNET and attached to one of the VMs. Deleted all&all rules of default Security Group. So I expect all in&out traffic should be disallowed on the new interface of new VM (ID:19). But it wont work.

Checked the security group on cli:
[oneadmin@node01 ~]$ onesecgroup show 0
SECURITY GROUP 0 INFORMATION
ID : 0
NAME : default
USER : oneadmin
GROUP : oneadmin
PERMISSIONS

VIRTUAL MACHINES
UPDATED : 13,15,16,17,18,20,21,22,23,24
OUTDATED :
ERROR :

That VM is not in the list. onesecgroup commit 0 doesnt make any change.
VNET details:
[oneadmin@node01 ~]$ onevnet show 6

Could you send the output of iptables-save for the host?
