why ftp won't work behind the NAT ?!
You can insmod the ip_masq_ftp and work with ftp fine .

Subject: [SQU] ftp via proxy-firewall
Hello.
 I have a squid proxy set up behind a firewall.
The packets from the squid proxy are diverted
threw a NAT dameon on the firewall.  Having failed
to configure squid to use ftp-gw on the firewall,
I am attempting to have ftp work using NAT as
well.  I understand why normal-mode ftp doesn't
work.  I've adjusted the squid.conf option
"ftp_passive" to "on". When I ftp from netscape
(configed to use the proxy)  an error is returned
after a short while stating " Squid sent the
following: NLST and recived the reply: No files
found".  The packet log below is a capture of this
conversation.  The logs on the proxy will display
the error: "proxy2# Feb 16 15:41:24 proxy2
squid[3137]: ftpTimeout: timeout in SENT_PASV
state."
 If I ftp to the same server from the command
prompt on the proxy,  I recive an error that looks
simular to the error that is returned while
attempting the same with normal mode ftp. The
error reads "425 Can't build data connection:
Connection timed out."
 Would anyone know what the problem may be, or
have a better solution?  I really don't want to
run any proxy like software on the firewall if it
can be advoided, and would rather not have clients
connect direct to the firewall,  I'd like to have
the proxy as the only trusted internal host.
ftp-gw was an attempt at gettting around the ftp
normal-mode issue.  Thanks for your time,  please
let me know if you require more information.

some  information:
- 3 NICs in the firewall
-two different internet links
- FTP,  WEB, routers and external NICs on the firewall have internet
IPs.
-The proxy and internal NIC have registered IPS,
but they are not known or in any routing tables on
any internet routers.
-Web stuff works fine.
-natd alias outgoing traffic to the interface that points towards the
web and ftp server.
-FreeBSD firewall using natd
222.222.222.222= ftp server
222.222.222.111=NIC IP that natd alias to.
(I have changed the IPs from what they really are for this letter)
