RHAS piranha version? FTP support?

We are still running the piranha that came with RH 6.2.
Does anybody know if the problem with active and passive ftp has been 
fixed in the newer version?
I reported this to redhat support July 11, 2001 (ticket request is still 
open).  According to Redhat support on the phone last year, RH 6.2 OS 
could not handle this to to wait for a newer version of the OS.

Problem below:

When a user ftp through the high availability server to one of the ftp servers
using active ftp, he connects with no problems.  But when he issuses a command,
the users remote firewall rejects the request because it comes from the high
availability servers's ip address and not the virtual servers's address.

I have already try using NAT on my firewall to correct the problem but it still 
happens in either IE or netscape (can't remember which)
