Trying to FTP: error 421 Service not available

[humayun]

I am trying to ftp to a client site and I am getting the following error message. What could be wrong?

421 Service not available, remote server has closed connection
Passive mode refused.

Thanks.

Also, can someone please elaborate on this error I am getting.

IP address mismatch in port/227 command - header IP different from command IP

Thanks.

Check which mode is used on client and server side (active or passive, you can change mode by command passive after logon to ftp server), and check which ftp rule you created in rule base (with ftp or ftp_pasv).

How do you change mode to " command passive", as you mentioned. And where exactly can I check on the remote client's ftp server.

Thanks.

after logon on ftp server (like "ftp x.x.x.x", then input user login & pass);
you'll see command prompt "ftp>";
input "passive";
and you'll see "passive mode off"
