Hi all,
We have a server behind ASA/inside network with PVT ip. Nat to internet via ASA public/outside. When initiate FTP to a outside vendor site using windows command line ftp..
1. The login successful
2. ftp> ls
200 PORT command successful.
550 Cannot connect to 20.20.20.20:30997 - Error 0.
20.20.20.20 --> outside IP of the ASA
The port changes for every attempt..(random port like 31000, 31007): but message is same.
The server able to FTP to another vendor with no issues via the ASA.
on ASA:FTP commands are enabled.
ftp mode passive
inspect ftp
Any Suggestions..?
Thank you
MS
