Yes. Just set up ipfwadm to do that (it's a firewall thing, not
necessarily an IP Masquerade thing).

Nate,

Look for a program called 'redir'.  I think it is on sunsite.unc.edu.
Try the system/Network/daemons directory.

1. IP Masq'd Workstation to connect to IP Masq'd Workstation

I have setup my Linux Box with IPMasq. Everything runs fine from my win box
behind the proxy. Now I just encountered a problem. I have tried to connect
to an ftp server that is behind NAT server which are both on winboxs

I can't seem to connect to the FTP even when the FTP Client is set to
passive mode. Does anyone know whether there is anything I can do on my side
of the connection such as reconfiguring my Linux Box to fwd properly?
