I created a secondary by following the instructions on this link below. it works great but the two internal subnets are able to ping each other. I need to have two subnets and have a block so that one subnet can not reach the other. Example, lan subnet primary is 192.168.2.1
secondary is 192.168.0.1 I don't want anything on 2.1 to be able to access 0.1 subnet

I would have to assume that the subnets are on two separate VLAN/zones.  Check your firewall policy from zone A>zone B and set a rule to deny all and then create another policy for zone B>zone A for deny all.  That should block all your traffic between the two LANs.

If you can't do it through the firewall just redirect the traffic between the LAN subnets with an intentional bad gateway.  Not nearly as clean but it will stop the traffic.

Source                Dest                    Gateway
192.168.0.x       192.168.2.x          1.1.1.1

Try the firewall route if at all possible.

haven't had a chance to try it.  I'm not exactly sure of how to create those zones. I will try though.

Configuring Zones - Chapter 17.  This is assuming you have the 4.0 enhanced OS.
