Problem FTP on ASA 5510 (port not stantard)
Posted on 2014-10-30
I configured a dedicated server (on my LAN) just for the FTP function.
I configured many ftp ports, 21, 2101, 2102, 2103...etc...etc...
From my LAN, It works perfectly.
I configured a NAT translation on my ASA 5510. (with a rule which accepts all tcp connections)
From external, it works on the port 21,
but for the others ports, I have always an error message during the listing of the folder...(timeout)...
The problem is the ASA...somewhere it blocks the communication....
Can you help me ?
