Micrel KSZ8993 eth1/eth2 comm with eth0

I am using 2011R1-RC3, the BF537, DSA, and a 3-port Switch, the KSZ8993.
My board's system is connected to the KSZ8993's internal interface, eth0.

 

The KSZ8993's external port, eth1, is connected to the LAN through an external Switch.
The KSZ8993's external port, eth2, is connected to PC #1.

 

Another PC, PC #2, connected to the LAN elsewhere, and can communicate with the system
app running on the bf537, as its LAN cnxn is thru external interface, eth1, setup with
the board's IP addr.

 

PC #1, however, connected thru eth2, cannot communicate with the system app running on the bf537.
But, PC #1 can communicate with any other device on the LAN.

 

All 3 interfaces have the same MAC addr.


Question:

 

Is it possible that only 1 of the KSZ8993's two external interfaces, eth1 or eth2,
can communicate with the internal interface, eth0, but not both? Or, am I missing something?


Thanks,

 

Steven
