      Hi,

      This is my HAproxy conf. file and everything works right without FTP connection.

      I can not access the servers via FTP.

       global

 log 127.0.0.1   local1 notice
#log loghost    local0 info
maxconn 4096

    acl server4_URL hdr_dom(host) -i domain4.com

use_backend server1 if server1_URL
use_backend server2 if server2_URL
use_backend server3 if server3_URL
use_backend server4 if server4_URL
use_backend server5 if server5_URL   

backend server1

server web-first 192.168.1.2:80

backend server2
mode http
server web-first 192.168.1.3:80

backend server3

backend server4
mode http
server web-second 192.168.1.6:80
 
backend server5
mode http
server web-third 192.168.1.7:80

      I tried this: it did not work

      listen FTP :21,:10000-10250
mode tcp
server ftp01 192.168.1.4 check port 21

      What should I do for it?
      Thank you.

        Have you set pasv_address on the FTP machine?

              I added this lines in HAproxy conf. file:

               listen 
    bind <public IP>:21
    mode tcp  
    server web-second <local IP>:21 check

              Result:

                The configuration file has an issue, I am
                reviewing the configuration file. Before restarting running ‘haproxy check’ so you make sure it doesn’t fail on restart.

                  You're missing a name declaration beside the listen in the last example that you posted.
                  listen <my_service_here>
                  and optionally the hostname and bind port:
                  listen <my_service_here> localhost:8080

                    I have one "listen" and for statistics.
                    Could you give an example for FTP listen?

                      @emsanator : Check line 81 of your file. The error states that it couldn't find a declaration for listen on that line. (/etc/haproxy/haproxy.cfg:81)
                      I expect that you're missing "listen myftpserver" or similar.

                         listen FTP  
       bind *:21,:10000-10250
       mode tcp 
       server ftp01 192.168.1.4 check port 21
       server ftp02 192.168.1.5 check port 21

                        I do not get HAproxy error with this method

                        FileZilla Log:

                         Status:	Connecting to <Public IP>:21...

                        I tried every way in few days but I can not connect with FTP.

                          As @scottalanmiller mentioned above, you'll have to configure pasv on ftp and ensure your client is configured to use it as well.

                          within vsftpd.conf :

                          pasv_enable=YES
port_enable=YES
pasv_min_port=10000
pasv_max_port=10250
pasv_address=IP.OF.BOUND.INTERFACE
pasv_addr_resolve=NO
