In addition to firewall configuration, ensure that the network infrastructure, such as routers and switches, is properly configured to allow VPN traffic to pass through. If the Sophos Firewall is behind another firewall or router, configure port forwarding or a DMZ to ensure VPN traffic reaches the Sophos Firewall.

Configuring VPN Authentication

Authentication is a crucial aspect of VPN security. Sophos Firewall supports a variety of authentication methods to verify the identity of VPN users. The most commonly used authentication protocols are PAP (Password Authentication Protocol), CHAP (Challenge-Handshake Authentication Protocol), and MS-CHAP (Microsoft Challenge-Handshake Authentication Protocol). Choose the appropriate authentication protocol based on your network's security requirements and compatibility with client devices.

To configure authentication in Sophos Firewall, navigate to the "Authentication" section in the VPN settings. Here, you can choose the desired authentication protocol, configure user credentials, and enable additional security features such as two-factor authentication for enhanced security.

Ensure that strong and unique passwords are enforced for VPN users to prevent unauthorized access. Consider implementing multi-factor authentication (MFA) for an extra layer of security. Sophos Firewall integrates with popular MFA methods such as SMS-based codes, email-based codes, or third-party authentication apps like Google Authenticator or Duo Security.

Encryption and VPN Protocols

Encryption is vital for securing VPN connections and ensuring the privacy of data transmitted over the network. Sophos Firewall supports various encryption protocols, including IPsec (Internet Protocol Security), SSL/TLS (Secure Sockets Layer/Transport Layer Security), and OpenVPN. These protocols provide different levels of security and performance, so it is important to choose the appropriate protocol based on your network requirements and the devices or applications accessing the VPN.

In the VPN configuration menu, navigate to the "Encryption" section to choose the encryption protocol and set the encryption parameters. It is recommended to use AES (Advanced Encryption Standard) with a key length of 256 bits for optimal security. However, if compatibility with older devices or applications is a concern, you may need to choose a less secure encryption algorithm. Evaluate the balance between security and compatibility when configuring encryption for your VPN.

In addition to encryption protocols, Sophos Firewall also supports various VPN protocols, including IPsec and SSL VPN. IPsec is widely used for site-to-site VPNs, connecting entire networks together, while SSL VPN is popular for remote access VPNs, allowing individual users to securely connect to the network from anywhere. Choose the appropriate VPN protocol based on your network architecture and user requirements.

Creating VPN Connections

Now that the Sophos Firewall is properly configured and the necessary authentication and encryption settings are in place, it is time to create the VPN connections. Sophos Firewall supports various VPN connection types, including site-to-site VPN and remote access VPN. The steps for creating these connections may vary slightly, but the overall process remains similar.

To create a site-to-site VPN connection, navigate to the "Site-to-Site" section in the VPN settings. Here, you can define the VPN gateway, specify the remote network, and configure routing options. Ensure that the remote network's IP addresses do not overlap with the local network to prevent routing conflicts. Configure the appropriate routing rules to allow traffic between the local and remote networks.

For remote access VPN, navigate to the "Remote Access" section and choose the desired VPN protocol, such as IPsec or SSL VPN. Specify the user authentication method, encryption parameters, and configure additional settings such as split tunneling or access control lists (ACLs). Split tunneling allows users to access both the VPN and the internet simultaneously, while ACLs allow fine-grained control over which resources users can access over the VPN.

Once the VPN connections are created, Sophos Firewall generates configuration files or connection details that can be provided to clients or other network administrators to establish the VPN connections. Sophos Firewall supports various VPN client software and compatibility with popular operating systems and devices.
