Traffic restriction between two vlan

Julio Calle 
I have an interface with two vlan assigned, vlan A and Vlan B, both work fine, but I can not restrict traffic from Vlan A to Vlan B

any ideas?

    As long as you have a Sophos UTM in between and have the Sophos UTM as default gateway (and not route VLAN on L3-switches) there should be no access if you do not specifically allow it through firewall.

    However if both VLAN's use web filtering you may need to take additional steps to prevent HTTP(s) traffic between the 2 VLAN's.

    Please explain in more detail your configuration so we are able to give you more specific help.
