Did you try taking out the FTP_PORT and FTP_PASSIVE out of the rule and just
leave normal FTP in? Maybe you could create a 2nd rule right under the
normal FTP rule to allow FTP_PORT and FTP_PASSIVE. I've seen problems when
you have FTP and FTP_PORT in the same rule with it not allowing people to
connect to a simple FTP. It allows the login, but will disconnect
immediately after the login as soon as you issue the first command. Just
letting the rule say "FTP" as the service fixed this.

Actually we also have had this problem.
Only a downgrade to SP2 brought a solution.

Betreff: [FW1] Help!! Simple FTP Problem
Does anyone tell me how i can deal with
simple FTP connection via FW1-v4.1 SP 3 (on AIX) ??
This was like a duplicated question, but probably
my case would be simpler.
FTP server is on DMZ, FTP clients are in both
internal network and Internet.
FTP server itself should be no problem because
another machine on DMZ is able to connect with ftp.
it would be a problem when ftp was going through the FW1.
i am trying FTP connection from Internet (or internal) side
towards DMZ, and the first connection
(which means just connect to the server,)
is no problem.
when the server is trying to reply to the client, the Firewall
drop the connection based on rule zero!!
the client cannot log in, that is..,
it droped before the ftp control would be established.
i checked that both "Enable FTP Port" and "Enable
FTP PASV" are checked, on the "service" of "Properties Setup."
Address translation would be quite simplly set.
ANY FTP(Global)------>ANY FTP(Private)
ANY FTP(Private)----->ANY FTP(Global)
Also, the current policy is just:
Source Destination Service
ANY FTP_server(Global IP) ftp accept
ANY ANY ANY Drop
Please help me!!
appriciate with regards
