### Linux

On Linux, firewall settings can be managed by using `ufw` or `iptables`. The commands below are provided for reference only. Please verify the exact commands for your Linux distribution before making any changes.

#### ufw

1. Check the firewall status:
   ```bash
   sudo ufw status
   ```

2. Enable or disable the firewall:
   ```bash
   sudo ufw enable
   sudo ufw disable
   ```

3. Check the ufw version:
   ```bash
   sudo ufw version
   ```

4. Set the default policy for external access:
   ```bash
   sudo ufw default allow
   sudo ufw default deny
   ```

5. Allow or deny external access to port 53:
   ```bash
   sudo ufw allow 53
   sudo ufw deny 53
   ```

6. Allow a specific IP address to access all local ports:
   ```bash
   sudo ufw allow from 192.168.0.1
   ```

#### iptables

1. Check the firewall status:
   ```bash
   service iptables status
   ```

2. Start or stop the firewall:
   ```bash
   service iptables start
   service iptables stop
   ```

3. Restart the firewall:
   ```bash
   service iptables restart
   ```

Alternatively:

1. Go to the `init.d` directory:
   ```bash
   cd /etc/init.d/
   ```

2. Check the firewall status:
   ```bash
   iptables status
   ```

3. Temporarily stop the firewall:
   ```bash
   iptables stop
   ```

4. Restart `iptables`:
   ```bash
   iptables restart
   ```

For Linux environments, search Baidu or Google for the exact procedure required to disable the firewall on your current distribution.

## Disable Windows Defender Antivirus

Disable the built-in antivirus protection on the system, and install third-party antivirus software if needed.

### Server 2019

Open **Server Manager** > **Local Server** > **Windows Defender Antivirus** > **Real-time Protection**, then disable all cloud-delivered protection options.
