How To Ufw Allow Nginx Http Digitalocean
What is UFW for Nginx on DigitalOcean?
UFW (Uncomplicated Firewall) is a firewall application package for use with the Ubuntu Linux operating system. It is designed to ease the process of setting up and maintaining an effective firewall solution on a DigitalOcean hosting machine. UFW works by controlling network access to specific hosts or services. It can be used to protect a DigitalOcean hosted machine from malicious incoming traffic by blocking access to vulnerable services or ports. It can also be used to allow appropriate incoming traffic, such as web requests, to be passed to the desired service, such as Nginx.
Ubuntu Firewall Setup for Nginx on DigitalOcean
Before you can UFW allow Nginx http on DigitalOcean, you need to configure the firewall. To do this, you need to access the command line of your DigitalOcean hosted server. This can be done using the built-in terminal in the DigitalOcean control panel or an SSH connection. Once you are connected to the server, you need to install UFW:
$ sudo apt-get install ufw
You can then start the firewall:
$ sudo ufw enable
By default, all incoming connections to the server are blocked. To allow all outgoing connections from the server to the internet, you need to allow the default outgoing connection policy:
$ sudo ufw default allow outgoing
Allowing Nginx Http on DigitalOcean
Once you have the firewall enabled on your server, you need to configure it to allow incoming traffic through port 80, which is the port typically used for HTTP requests. You can do this by running the following command:
$ sudo ufw allow 80/tcp
This will allow all incoming connections to port 80 on the server. You can also specifically allow connections to the Nginx web server by running the following command:
$ sudo ufw allow proto tcp from any to any port 80
Checking UFW Status on DigitalOcean
Once you have allowed Nginx HTTP on DigitalOcean, you should run the “ufw status” command to check that the firewall has been successfully configured. This will show an output similar to the following:
$ ufw status
Status: active
To Action From
— —— —-
80/tcp ALLOW Anywhere
80/tcp (v6) ALLOW Anywhere (v6)
Disabling and Deleting Firewall Rules on DigitalOcean
If you need to delete or disable a rule on the firewall, you can use the “ufw delete” command. For example, if you wanted to delete the rule that allowed HTTP access on port 80, you would run the following command:
$ sudo ufw delete allow 80/tcp
You can also use the “ufw disable” command to turn off the firewall completely. This is not recommended unless you really need to turn off the firewall.
$ sudo ufw disable
