Firewall not blocking traffic

[cubert]

I have a 2 LAN / 2 WAN network that I wanted to stop all traffic between the 2 LANs.  I placed in several rules in both Lan segment to prevent access but I could not stop a ping in progress or prevent it from starting when we killed ping and restarted the ping.

except for the antilockout rule my block rules were first inline. Any ideas on why I could'nt get ping to drop between interfaces?

Active connections aren't affected by firewall rule changes on any stateful firewall, kill the states if you want them to be dropped.
