Sorry, I meant to say that the "FTP-PASV" option was in fact checked on both firewalls (recall 1 worked, 1 doesn't), as is the "FTP-PORT" option on both firewalls. There was some suggestions in previous postings that disabling those options made them work?? so I tried that on the firewall that doesn't work, but still no luck. Any other ideas??
Thanks,

There are multiple suggestions on solving such problems
in the list archives. ( www.securepoint.com <http://www.securepoint.com> ).Try enabling passive-mode FTP on the FW.
(Under Policy->Properties)

Subject: [FW1] MS FTP behind NAT
I'm having a rather irritating problem: someone behind one of our FW-1
firewalls has to use Microsoft's command-line FTP (from win98, win2k, and
winnt) as part of a batch script (I know it's junk, but the scripter won't
use anything else). I tried it behind a different FW-1, and it worked.
Here is the common configuration between the 2 firewalls:- FW-1 4.1 on NT sp 6a
- hosts are being NATted, the test PC's are statically mapped to valid IP's
(doing it without the static NAT gives a host of errors)- ftp is enabled in the rulebase for outbound connections
Here's what's different between the 2 firewalls (firewall A functions
properly, firewall B does not):- firewall A is running FW-1 service pack 2, firewall B is running FW-1
service pack 3- SYNDefender is set to "none" on firewall A and is set to "passive gateway"
on firewall B- under "logs and alerts" in Policy > Properties, "log established TCP
connections" is checked on firewall A and is unchecked on firewall B.Those are the only differences I can find. What happens when I try to
connect to an ftp server behind firewall B is that I can log in, but when I
try to do a directory listing or cd to a directory I get an error saying
"invalid port command" - no such error from behind firewall A.Any suggestions??
thanks,
Glenn
