3. Enter the port number of the other device in the Peer Port field.
4. Click on the Apply button.

The WireGuard connection will now be active.

Advanced Configuration

WireGuard on Synology NAS offers advanced configuration options to meet diverse networking requirements. These options allow users to configure multiple clients or networks, customize security settings, and enable advanced features like split tunneling and load balancing.

Configuring Multiple Clients or Networks

To configure WireGuard for multiple clients or networks, users can create multiple profiles within the Synology Network Manager. Each profile represents a separate WireGuard tunnel with its own set of peers, keys, and settings. This allows users to establish secure connections with different devices or networks simultaneously.

Advanced Use Cases

WireGuard’s advanced features enable various use cases:

• • -*Split Tunneling

    Directing specific traffic through the WireGuard tunnel while allowing other traffic to pass through the local network connection.

-*Load Balancing

Distributing network traffic across multiple WireGuard tunnels to improve performance and reliability.

-*Custom DNS Servers

Configuring custom DNS servers to enhance privacy and control DNS resolution.

Security Considerations

WireGuard offers significant security benefits, including:*

-*Strong Encryption

WireGuard uses modern and robust encryption algorithms, such as ChaCha20 and Poly1305, to protect data in transit.

• • -*Simplified Configuration

    WireGuard’s configuration is straightforward, reducing the risk of misconfigurations that could compromise security.

-*Open-Source Code

WireGuard’s open-source code allows for independent auditing and verification of its security.

However, it’s important to be aware of potential security risks associated with WireGuard:*

-*Client Compromise

If a client device is compromised, an attacker could gain access to the WireGuard connection and intercept or manipulate data.

• • -*Network Exposure

    WireGuard connections can expose internal network resources to external clients if not properly configured.

-*Denial of Service (DoS) Attacks

WireGuard is vulnerable to DoS attacks that can disrupt the availability of the VPN connection.

Recommendations for Securing a WireGuard Connection on a Synology NAS

To enhance the security of your WireGuard connection on a Synology NAS, consider the following recommendations:*

-*Use Strong Passwords

Generate complex and unique passwords for both the server and client devices.

• • -*Restrict Client Access

    Limit access to the WireGuard connection to authorized clients only.

-*Enable Two-Factor Authentication (2FA)

Implement 2FA to add an extra layer of protection against unauthorized access.

-*Use a Firewall

Configure a firewall on the Synology NAS to block unauthorized access to the WireGuard port.

-*Keep Software Up-to-Date

Regularly update WireGuard software on both the server and client devices to patch any vulnerabilities.

Troubleshooting

If you encounter issues setting up or using WireGuard on your Synology NAS, here are some common troubleshooting tips and solutions:

First, ensure that you have correctly configured WireGuard on both your NAS and the client device. Check that the IP addresses, ports, and keys match on both ends.

Connection Issues

• Cannot establish a connection: Verify that the WireGuard interface is enabled on both the NAS and the client. Check if there are any firewall rules blocking the connection.
• Connection drops intermittently: Ensure that the network connection between the NAS and the client is stable. Check for any network congestion or interference.

Error Messages

• “Interface is not found”: The WireGuard interface may not be properly configured. Check the interface settings and ensure that the correct device is selected.
• “Handshake failed”: The keys or IP addresses used for the connection may be incorrect. Verify that the keys and addresses match on both the NAS and the client.

Collecting WireGuard Logs

To collect WireGuard logs for troubleshooting, enable logging in the WireGuard settings on the NAS. The logs can be found in the following location:
