Connect to ftp thru another machine

[Sub Zero]

Hello,

I need to connect to a remote FTP server via a machine. The machine that I
have to connect has 2 eth interfaces. I connect via eth0 and the machine
should connect to a non-internet routable address using eth1 to a 10.x.x.x
type static address.

What is your recommendation? The server in the middle is CentOS with cPanel.

Have a nice day.
