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
|
|
```
|
|
|
|
2. **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."
|
|
- For example: In Firewall configuration make sure Port TCP:32400 is open for Plex Server.
|
|
|
|
Remember, firewalls protect your network by filtering traffic based on predefined rules. Choose the method that suits your preference! 😊🔥
