• I host my website on EC instance. It was working fine today I add security group for tcp 6001 after that I use command sudo ufw enable after that my EC2 instance is not connect through ssh.
• The quickest way to manually add a new rule for a different SSH port would be with the following command: sudo ufw allow /tcp inserting your particular port into the command. While you haven't specifically asked, remember that you need to make your port number change in the file /etc/ssh/sshdconfig.
• Sudo ufw allow ssh. After this enable ufw if it is disable. Sudo ufw enable. Now check the status wheter ssh or port no 22 is allow. Sudo ufw status UFW status. Now you are ready to use. In few step you are ready to use OpenSSH server,just make sure that ssh port is enable in UFW Firewall. There are many options in ssh, if you want.

Ubuntu comes pre-installed with a firewall configuration tool, UFW (Uncomplicated Firewall). UFW is easy to use for managing server firewall settings.

This tutorial shows you how to disable and enable an Ubuntu UFW firewall using the command line.

• Command line / terminal window
• User with root or sudo privileges

Before disabling the UFW firewall, it is a good idea to check its status first. In Ubuntu, the firewall is disabled by default. How do you know if your firewall is on?

To check the current status of the firewall, execute the command in your command terminal:

In this example below, the output shows that the firewall is active.

As we have determined the current state, now we can proceed to disable the UFW firewall.

A firewall is a vital element in a network and server security. However, while testing or troubleshooting, you might need to shut down or stop the firewall.

To disable the firewall on Ubuntu, enter:

The terminal informs you that the service is no longer active.

If you disable the firewall, keep in mind that your firewall rules are still in place. Once you enable the firewall again, the same rules that were set up prior to the deactivation will apply.

Learning how to enable the firewall on Ubuntu is vital.

Ufw Ssh Port

To enable the firewall on Ubuntu, use the command:

As with the ‘disable’ command, the output confirms that the firewall is once again active.

UFW does not provide complete firewall functionality via its command-line interface. However, it does offer an easy way to add or remove simple rules.

A good example is opening an SSH port.

For example:

Once the terminal confirms that the rule is now in place, check the status of the firewall with the ‘status’ command:

The output is going to reflect the fact that an SSH port is now open.

If you need to reset all rules back to default settings, use the reset command:

After confirming the action, by typing y, the firewall settings revert to their default values.

In this guide, you learned how to disable and stop the firewall on Ubuntu. We also showed you how to enable the firewall and reset settings.

Now you know the options available with the UFW tool. These commands provide an excellent foundation to explore firewall functions and settings.
