You will probably need to set up additional routing tables via the "ip
route" command.  One table will need to be the machine default and one will
need to be the table that FTP traffic uses.  Each table would use the upstream
gateway for the connection that you want them to use as their default route. 
You will probably have to MARK the traffic that qualifies as FTP traffic via
iptables and use an "ip rule" to match on the fwmark stating that
marked packets need to use the FTP routing table.
