I'm having a little problem here with FTP.  I'm trying to ftp from a machine
behind a linux firewall, across the internet to a machine behind a linux
firewall ... the target machine is an SCO Unix system behind a RH 6.2
firewall running ipmasqadm to reverse-map port 21.  I can get a control
connection just fine, but can't get a data connection.  

I'm running on a Win2k system using CuteFTP.  The error I get is:
   "425 Can't build data connection: No route to host." 

and prior to the error message I see where the client sent "PORT
10,5,10,18,13,111".  This all makes sense and I understand the error, but
I'm not sure how to get around it. 

I already know PASV mode won't work 'cause the SCO system is using a private
address.

Access from the linux firewall on my site works fine, but I'd like to be
able to access from behind my firewall.

Any ideas?
