  One thing I noticed missing, mind you, I don't use masq, but I believe
the 'input' and 'output' rules in ipchains is whats causing your problems.
My system isn't using masq so I have no rules in 'forward' but you still
need to accept ftp with the 'input' and 'output' in order to forward them
to the other systems.
  Of course I could be completely out in right field here, as I havn't
messed with masq, but I would assume its the same, everthing still has to
come through 'input' and 'output' before it can goto 'forward'.
