Introduction
Setting up a Virtual Private Network (VPN) on Windows Server 2019 is an excellent way for businesses to ensure secure remote access to their network. This guide will walk you through the steps of installing and configuring a VPN server using the Remote Access role in Windows Server 2019.
Step 1: Install the Remote Access Role
First, you need to install the Remote Access role. Log in to your Windows Server 2019 system as an Administrator. Open the 'Server Manager' dashboard and click on 'Add roles and features'. Proceed through the wizard until you reach the 'Roles' page. Here, check the 'Remote Access' role and click 'Next'. On the 'Role Services' page, select 'DirectAccess and VPN (RAS)', then click 'Next' and 'Install'. The installation might take a few minutes.
Step 2: Configure Routing and Remote Access
Once the role installation completes, open 'Server Manager' again, and in the 'Tools' menu, select 'Routing and Remote Access'. Right-click your server name and select 'Configure and Enable Routing and Remote Access'. In the wizard that appears, choose 'Custom Configuration', then select 'VPN access'. Follow through the wizard, finish the configuration, and start the service.
Step 3: Configure Authentication and Network Policies
Authentication is crucial for VPN security. Open the 'Routing and Remote Access' management console. Navigate to 'Remote Access Logging & Policies', then right-click 'Network Policies' and select 'New'. Name your policy and set conditions based on your security requirements (e.g., Windows Groups containing VPN users). Under 'Constraints', configure the authentication methods, such as MS-CHAP v2 or EAP. Finish by setting the access permission to 'Grant access'.
Step 4: Set Up User Accounts and Groups
For users to access the VPN, they need proper credentials. In the 'Server Manager', go to 'Tools' > 'Active Directory Users and Computers'. Create a new user group specifically for VPN access. Add users to this group as necessary. Ensure these users are enabled and have permission to dial in remotely, which can be set in the user profile under the 'Dial-in' tab.
Step 5: Configure Your Firewall and Test the Connection
Adjust your firewall settings to allow VPN traffic. Typically, this involves allowing port 1723 for PPTP or the appropriate port for your chosen protocol. Finally, test your VPN connection using a client computer. Set up a VPN connection pointing to your server's public IP address, authenticate with a user’s credentials, and verify that the connection is secure and stable.
Conclusion
Setting up a VPN on Windows Server 2019 enhances your network’s security by providing a secure method for remote access. By following these steps, you can ensure that your VPN is correctly configured and ready to serve your organizational needs. Remember, regular maintenance and updates are crucial to keep your VPN server secure.
