Untangled security between networks

Hello,

I have an untangled box with 5 nic's

Nic 1 - Internet
Nic 2 - 192.168.1.1
Nic 3 - 192.168.2.1
Nic 4 - 192.168.3.1
Nic 5 - 192.168.4.1

I have everything configured as default using version 10, and all networks can see each other. I tried putting in a filter rule to deny all traffic between nic 2, 3 and 4. And I need them all to see network 5 (print server) however every rule I put in place I can still ping across all networks. Is there anything I'm missing?
