1. Need Simple Help With Port Forwarding And FTP

I don't think I've ever seen so much confusion over how to get something
done as I have in searching for documentation on how to do this.

Here's typical documentation: ...if you have this kernel, then you need that
patch, but for that kernel, you need this patch, along with that module,
however if you have the old patch you need the new module or the patched
patch, else the patched kernel re-compiled with the old kernel patch module
that's been compiled like the new kernel with no patch at all, except when
you've patched the kernel patch with the non-compiled module patched kernel
patch module kernel written in Chinese patch, translated to Russian module,
patched to thousand island and Italian, of course unless it's after 7PM EDT
in which case you just patch your RTC, after that you won't need any patch
at all, hell you don't even need a kernel...

It's ridiculous.

I'm running RHL v7.0, kernel 2.2.16-22
I'm running ipchains and ipmasqadm
I'm running ProFTP v1.2.1

I have machine A running the above Linux config acting as a firewall/file
server.
I have machine B running behind the firewall with Windows 98 and an FTP
server on port 21.
I want people who request an FTP session with machine A to be forwarded to
the FTP server on machine B.
Real simple.

So far, all I've found is this:

/usr/sbin/ipmasqadm portfw -a -P tcp -L $machineAip 21 -R $machineBip 21
/usr/sbin/ipmasqadm portfw -a -P tcp -L $machineAip 20 -R $machineBip 20

But it doesn't work. I've checked connectivity and I've disabled anything
else that could mess with ports 20 & 21.

What am I missing? Can I do this - meaning forward FTP users to an internal
server?
