About synchronizing predict session on A-A with asymmetric routing environment.

Hello,

I am testing to allow for FTP(all both active & passive mode) on A-A with asymmetric routing environment.

Session of control channel on FTP such as login has no problem. But I can not connect data-channel.

It seems cutting data session.

So I tried packet capture in FW.

Syn/Ack packet on data-channel  was dropped by FW.

I guess root cause of this issue is FW can not synchronize predict session on A-A with asymmetric routing environment?

Is it right?

I need your advise.

Thanks,

KC Lee
