Summary0004470: Inter-zone Traffic And Policy Routing Issue

Not sure if this is a bug or it was supposed the way on version 2.5.1.

Traffic from Orange zone to Green zone on open ports was failed when Policy Routing was applied to Orange zone too.

By just setting up a rule on Inter-zone Traffic, where
            Orange -> Green, <ports>
the traffic would be dropped, as logged in firewall log as "ZoneFW.Drop"

To solve this, do following,

1. Setup Static Routing, and enable it
      Source Network: <Orange Zone Net IP/CIDR>
      Destination Network: <Green Zone Net IP/CIDR>
      Route Via -> Static IP : <Green Zone Gateway IP>

2. Setup Inter-zone Traffic, and enable it
      Orange -> Green, <ports>

3. Apply the Policy Routing that you want

Doesn't matter of the steps sequence, once all setup properly, it would work.

Additional InformationIn my case, Endian Firewall was setup with BLUE, ORANGE and GREEN Zones.

The Policy Routing was setup to divert all traffic from ORANGE and BLUE zone to use 2nd uplink connection, where GREEN zone was using main uplink card.
