Bassackwards IP Forwarding?

I have a V5R1 machine that makes a PPP connection to a remote host. I can
FTP to that remote host from the V5R1 machine, no problem.

I have an V4R5 machine that can't do PPP due to no suitable hardware. The
two machines are connected via token-ring for both TCP/IP and SNA.

I would like to FTP from the V4R5 machine to the remote host via the V5R1
machine, using V5R1 as a gateway.

I have turned on IP Datagram forwarding in the TCP attributes of the V5R1
machine. I have defined a route on the V4R5 machine, specifying the full
address of the remote host, subnet mask of 255.255.255.255, and next hop as
the IP address of the V5R1 machine.

I did not IPL or cycle TCP/IP after changing the IP Datagram forwarding from
*NO to *YES on V5R1 machine.

It does not work (V4R5 FTP client just sits there - I assume it would
eventually time out).

Can this be done & any ideas what I am doing wrong?

Thanks,
-Marty
