Hi,

I have a server, Version 6.1, that has SSH, SSL, and plain FTP running. Every time a client tries to log into the regular FTP, they receive the following errors when pasv support is enabled on the client.

I have configured the firewall set up on the server which dictates the pasv ports. I have had these ports opened on the network firewall as well.

Any ideas?

Thanks,

That looks almost like the client does not have the correct port range opened on their side in their firewall or network equipment. Did they allow the corrects inbound for your FTP server external IP address?

I am having a similar issue - from the box itself.  I have tried 3 clients, IE, Filezilla and WSFTP Home.  WS Home appears to be able to connect to WS Server, but the other two will not connect in Passive mode (only active.)

As much as most people will respond with "tell people to use WS", this is client facing FTP server and I do not have the option to demand they change their client.  I need help resolving this so it works with more than just WSFTP.

This is running on a 2K3 Server (all latest SP,) with WSFTP Server 6.0, no software firewall - again, local so no hw firewall being utilized for this test.

Below is a log from Filezilla:

Status: Connecting to 10.30.0.3:21...
Status: Connection established, waiting for welcome message...
Response: 220-ftp.alllanguages.com V2 WS_FTP Server 6.0(54062500)

Response: 230 User logged in
Status: Connected
Status: Retrieving directory listing...
Command: PWD
Response: 257 "/Administrator" is current directory
Command: TYPE I
Response: 200 Transfer mode set to BINARY
Command: PASV
Response: 227 Entering Passive Mode (127,0,0,1,21,125). <-- IP Masked, was public space address
Command: LIST
Error: Connection timed out
Error: Failed to retrieve directory listing

From other computers it goes about the same until the last 4 lines where I do not get a response for PASV.

If anyone has seen this issue before and has any suggestions I would greatly appreciate it.
