Once you are on the server dashboard, look for the firewall settings. Vultr offers a built-in firewall feature that allows you to set up rules to control traffic to your server.
Step 3: Create Firewall Rules
Click on the "Create Firewall Group" button to start creating firewall rules. You can define rules based on IP addresses, ports, and protocols. For example, you can allow traffic on port 80 for web traffic and block all other ports.

After defining the firewall rules, apply them to the server you want to secure. The firewall will now filter incoming and outgoing traffic based on the rules you have set up.
Step 5: Test Firewall Configuration
It is essential to test your firewall configuration to ensure that it is working correctly. You can use tools like nmap to scan your server and check which ports are open and closed.
Step 6: Monitor Firewall Activity
