FTP Proxy IP Masquarading?

I have an ftp proxy (jftpgw) running on a box between two networks. Each
interface is behind a linksys firewall/router, and has a non routable IP
address (192.168.x.x). My problem is when my ftp proxy goes and connects to
an external site, the address it feeds the ftp server to return to is the
internal address of the interface. How do I mask it to the external
interface of the firewall/router?

Will this software work in passive mode? Use this if possible, then the
"reverse" connection is not needed.

If not you will need to run an active FTP proxy on the firewall. With
Linux you would use the ip_nat_ftp module. What the linksys equivalent
is or even if it has one I would not know, it is not really a question
for this group.
