Nat 1:1 passthrough

I've banged my head against the wall on this 1:1 NAT and I cannot get packets to flow back from the FTP box. I see the count go up on the destination rule, but the source rule stays at zero.

 

I've got a 13 IP block and i need to peel one IP out to attach directly to a external FTP server. My understanding is 1:1 NAT would do this for me, but for the life of me i cannot get the packets flowing properly.

 

I've put a VERY basic example together on an ERX with an administrative port eth0, a wan address on eth1 and a final destination on eth2. I have a FTP box with a public IP, so it is currently pluged into the ISP modem. I'd like to plug the FTP box into eth2 and plug the ISP into eth1 and have the address pass through.

 

If this is possible, would someone be so kind as to point out my mistake? I created all my entries via the GUI so if i'm missing a CLI only entry please let me know.

 

Steve
