Just installed EFW 2.3 and cannot access blue from green.

My setup:
----------------
green = eth0 = 192.168.0.1
blue = eth1 = 192.168.1.1
orange = eth2 = 192.168.2.1
red = eth3 = dhcp

Inter-zone firewall rule GREEN BLUE <ANY> ->  is installed by default.

Computer A gets ip = 192.168.0.10 DNS 192.168.0.1 Gateway 192.168.0.1 from DHCP on green

Code:
IPv4 Route Table
===========================================================================
Active Routes:
Network Destination        Netmask          Gateway       Interface  Metric
             0.0.0.0          0.0.0.0      192.168.0.1  192.168.0.10     10
         192.168.0.0    255.255.255.0         On-link   192.168.0.10    266
        192.168.0.10  255.255.255.255         On-link   192.168.0.10    266
       192.168.0.255  255.255.255.255         On-link   192.168.0.10    266
===========================================================================
Persistent Routes:
  None

Computer B gets ip = 192.168.1.10 DNS 192.168.1.1 Gateway 192.168.1.1 from DHCP on blue

If I can ping both green and blue ips of efw box, but not anything else on blue.
Code:
Pinging 192.168.0.1 with 32 bytes of data:
Reply from 192.168.0.1: bytes=32 time<1ms TTL=64

Code:

Try to create a global inter-zone rule, to accept ANY traffic from ANY (i.e. like disabling the firewall). Just to test if traffic passes this way.
 Enable all logs on inter-zone to see what happens.

Give us more tracert, from computer A to B, EFW and Red DHCP server. The same from computer B and endian box.
