crs and firewall

Is there any option to use firewall on CRS?
I have trunk port on ether1 with vlan 20,30,40 and ether 2 with vlan20, ether with vlan30 and ether 4 with vlan40

I have setup vlan-s with switch by example

Some of my idea is to block some traffic to servers on vlan10, vlan20 and vlan30

Or if some1 have some better idea how to do this I am open for solutions.

You can use the switch rules, bridge rules, or even the ip firewall depending on where and what you are trying to block. Can you give some more details?

I am trying now with bridge rules so if I make some progress I will post is.
