Change FTP Default Port To A Custom Port

Make sure you have installed VSFTPD server and its service is running.

Then edit VSFTPD configuration file and change the default port as described below.

On Debian / Ubuntu :

Edit /etc/vsftpd.conf file,

$ sudo vi /etc/vsftpd.conf

On RHEL / CentOS / Fedora / AlmaLinux / Rocky Linux:

Edit /etc/vsftpd/vsftpd.conf file,

$ sudo vi /etc/vsftpd/vsftpd.conf

Find the following line. If it is not found, add it.


And change the FTP default port 21 to a custom port, for example 210.


Save and close the file. Restart vsftpd service to take effect the changes.

In RHEL and its clones, make sure the port number 210 is not blocked in SELinux and Firewall.

$ sudo semanage port -a -t ftp_port_t -p tcp 210

If semanage command is not found, install the following package:

$ sudo yum install policycoreutils-python

To allow port 210 via firewall do the following steps.

In RHEL 7/ CentOS 7:

$ sudo firewall-cmd --permanent --add-port=210/tcp
$ sudo firewall-cmd --reload

In RHEL 6 / CentOS 6 :

$ sudo vi /etc/sysconfig/iptables

And add the new custom port line:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 210 -j ACCEPT

Save and exit the file and restart iptables service.

$ sudo service iptables restart

Finally restart vsftpd service.

$ sudo systemctl restart vsftpd


$ sudo service vsftpd restart

Now verify the port using command:

$ sudo netstat -tulpn | grep :210

Sample output:

tcp6       0      0 :::210                  :::*                    LISTEN      2610/vsftpd

If netstat command is not found in CentOS/RHEL, install the following package.

$ sudo yum install net-tools

Now, you can access the FTP server from all clients using URL: ftp <ftp-server-ip> <port-number>


$ ftp 210

Here, is my FTP server’s IP address and 210 is the FTP custom port.

Sample output:

Connected to (

220 (vsFTPd 3.0.2)

Name ( ostechnix

331 Please specify the password.


230 Login successful.

Remote system type is UNIX.

Using binary mode to transfer files.


As you see in the above output, we have accessed the ftp server using the custom port 210. You can use any port number of your choice. But, just make sure that custom port is not used by any other services.

Access FTP server using FTP client or Web browser

Similar to CLI method, you need to mention the custom port number while accessing the FTP server via a FTP client or a web browser.

Open your FTP client, for example FileZilla, and enter username, password and custom port in the respective fields and then click the connect button.

Access FTP server using Filezilla

To access the FTP server from a browser, the URL must be:
