Physical port isolation in EdgeRouter Lite

I am trying to basically isolate the two physical ethernet ports eth1 (192.168.1.24) and eth 2 (192.168.2.0/24) in EdgeRouter Lite.  I have created two firewall rulesets one for each as mentioned in the other post in the forum as follows:

Ruleset 1:

eth1 interface direction local,

Default action accept,

Rule 1: Destination (192.168.2.0/24) - All Protocols - Drop

Ruleset 2:

eth2 interface direction local,

Default action accept,

Rule1: Destination (192.168.1.0/24) - All Protocols - Drop

But still i can able to access the devices in the other network apart from my current network i am in.  How to achieve the isolation between eth1 and eth2.  Pleae advise me how to achieve this.  I am using web GUI for configuring thi setup.
