Hi,

I have two out FTP service, one in 21 port and work ok,
another in port 2121 (in another server), WS_FTP send "500
invalid PORT comand". Both service in W2YK machine's and
in IIS service.

In my MN-700 I "open" only port 2121 to my PC

Any idea?

Active mode issues are generally the fault of the client (not server side).
Active mode behind a firewall/shared connection is generally difficult to
do, because listening ports need to be dynamically opened (port is
determined by the ftp client during directory listings or transfers).

Many routers provide an ALG on port 21 to listen on FTP commands to sniff
out the port that needs to be open for active mode to work. However, that
only works on port 21 in most causes.... so it doesn't work on non-standard
ftp ports.

Your best bet is to setup your FTP server for passive mode FTP (you'll need
to forward an additional range of ports to the computer running the FTP
server, specify within IIS to use those forwarded ports, and tell IIS to use
your WAN ip as the passive mode ip).

Thank

I change FTP service in Server 1 to port 21, but not work:

"Timer cancelled blocking call"
"Accept error: blocking call cancelled"
"Retrieve of folder listing failed"

Error in WS_FTP in passive or not passive mode

Both server have equal config.!

Any idea?

Are you testing access from inside your own network, using external names?

If so, it will fail due to the MN700's lack of loopback support.

Loopback support should be added in the next firmware update.

Thank

Yes I all test from inside network, but why in one server
(1) run OK and other (2) NOT?. Both server with the same
config., but diferent IP and diferent ISP

Thank
