Certainly! Let's explore how to manage firewalls in Linux Mint using the terminal. There are a couple of options available:

1. UFW (Uncomplicated Firewall):

UFW is a straightforward and reliable firewall interface with both command-line and graphical tools.
To install UFW, open the terminal and run:
```
sudo apt install ufw
```
Verify if UFW is active with:
```
sudo systemctl status ufw
```
To allow specific ports (e.g., OpenSSH), use:
```
sudo ufw allow 22/tcp
```
To disable a port, run:
```
sudo ufw deny 22/tcp
```

Gufw (GUI for UFW):
- Gufw provides a graphical interface for managing UFW.
- Install it with:
```
sudo apt install gufw
```
- Open it from the menu: "Firewall Configuration."

Remember, firewalls protect your network by filtering traffic based on predefined rules. Choose the method that suits your preference! 😊🔥
