I'm having a bit of difficulty getting my system to correctly handle
portwarding and ftp traffic.

Here is the issue.  I have a redhat 7.0 server with IPchains and ipmasqadm
all loaded and running fine.  I am forwarding all traffic from port 2001 on
the extif to a dedicated ftp server at 192.168.100.5 on my internal net.
The forward rules seem to work fine, and the firewall is letting the traffic
in, and out, but i can't seem to get the system to work right.  I can login
to the ftp server from the outside and I pass all the authentication, but
when i try to get a directory, the system responds 

ftp> dir
200 PORT command successful.
425 Can't build data connection: Connection timed out.
ftp>

I tried this using the standard Windows ftp client and using CuteFTP with
PASV on and then with PASV off.  I can't figure it out.

I saw somewhere that inorder to work properly the ftp masq module needed to
be patched, but I couldn't figure out how to patch the module.  I found a
file that seemed to be the right patch, but it wouldn't apply correctly,
gfiving errors about entry lines and the like.

If patching is the right solution, could someone send me a link to the
latest patch for the module and give me a hint as to the correct command to
get the patch to apply correctly.  

BTW I'm running Redhat 7.1 on the internal ftp server with glftpd as the ftp
server on port 21.

thanks
