The problem is not on your Mac!

The problem is that the ftp destination host,, does not know
how to get back to your Mac's address

Unfortunately, there is really no way to "teach" how to reach
the Mac, since it's address is in RFC1918 "unroutable" (aka private)
address space.

So, you'll need to configure ipnat on the PC so that whenever it gets a
packet from it translates that into the PC's registered PPP
address.  Then, will know how to get back to your PC, and
your PC's ipnat will forward the packets back to the Mac.
