Vlan Firewall Issue

Hi,

I was wondering if it is possible to deny traffic from an Ethernet vlan interface to another ethernet vlan interface?

Details:

1 Physical Interface -> 2 Vlan interfaces with VLAN 110 & VLAN 120
1 Physical Interface -> 1 ethernet WAN port

VLAN 110: Production Network
VLAN 120: Guest Network

L3 Switch: 2 vlan's allowed, 110,120 and setted up as an DOT1Q trunk port.
no native vlan has specified.

Currently there are no FW rules setup between these 2 subnets / vlans.
However these 2 subnets are capable to communicate to each other what i like to prevent.

I tried already making deny rules between guest and production VLAN, seems they are ignored somehow.
