FTP Issue driving me crazy

[maeltor]

I have a single PFSense based firewall running 1.2.2
I CANNOT get FTP to work to servers behind the firewall.

I am NOT using NAT.  I have several routed interfaces of PUBLIC IPs on the LAN side of the firewall.
I have an ALLOW rule basically allowing any protocol, and any port, from my IP on the internet INBOUND to the FTP Server(s).

The problem is that I can create the FTP session, but it can't transfer any files.  An "LS" will just sit there forever until it times out.

I know the problem isn't the ftp servers because it is happening on multiple ftp servers (some linux, and some windows based).

Ideas?

As a side note, OUTBOUND ftp from a server behind the firewall to a server on the internet works JUST fine.

Since you're not using NAT:
Have you disabled the FTP-helper on all interfaces?

Yes I have disabled the FTP Helper application on both the WAN and LAN interfaces.
