Core planning steps before you deploy
- Decide on tunnel type and authentication: IKEv2 with certificate-based authentication is a common, secure choice for Always On VPN on Windows. It’s efficient and widely supported on client devices.
- Plan certificate infrastructure: you’ll typically need a PKI with a server certificate on the VPN gateway and client certificates issued to each device. You’ll also need root and intermediate CAs trusted by clients.
- Choose where to run the VPN gateway: Windows Server with RRAS Routing and Remote Access for on-prem setups, or a cloud gateway that supports this feature, depending on your architecture.
- Determine traffic routing strategy: full tunnel all traffic goes through VPN vs split tunneling only corporate traffic goes through VPN. Full tunnel is more secure, but it can impact performance if your gateway isn’t sized appropriately.
- Set up device management: use Group Policy for Windows, Intune, or another MDM solution to push VPN profiles to clients automatically and enforce connection rules.
- Prepare red-team-ready monitoring: ensure you have logging on your gateway, IDS/IPS in place, and a plan for monitoring VPN health, certificate expiry, and traffic patterns.
Server-side setup: Windows Always On VPN in a nutshell
Note: This is a high-level guide. The exact steps vary depending on Windows Server version and your network layout. Always test in a lab before rolling out to production.
Step 1: Prepare a PKI
- Install a Certificate Authority CA if you don’t already have one.
- Issue a server certificate for the RRAS VPN gateway from an enterprise CA.
- Issue client certificates for each user or device that will connect.
- Ensure the client devices trust your root CA or the intermediate CAs that chain to it.
Step 2: Install and configure the RRAS role
- On Windows Server, add the Remote Access role and select the VPN IKEv2 after the wizard.
- Configure the VPN gateway with the server certificate.
- Enable IKEv2 and VPN encryption settings that align with your security policy.
Step 3: Configure NPS Radius for authentication Free vpn addon for edge
- Install Network Policy Server NPS and configure RADIUS clients your VPN gateway and any network devices that will rely on RADIUS.
- Create policies that define who can connect and under what conditions e.g., certificate-based authentication, user groups, device posture.
Step 4: Set up VPN profiles and routing
- Configure a VPN connection with IKEv2, using certificate-based authentication.
- Set up a “full tunnel” policy if you want all device traffic routed through the VPN, or a split-tunnel policy if you only want corporate traffic routed.
- Ensure DNS is pushed to clients to prevent DNS leaks when connected.
Step 5: Push and enforce client profiles
- Use Group Policy or Intune to distribute VPN connection profiles to users’ devices.
- For Windows, create a VPN connection with the correct server name, authentication method, and tunnel type, then deploy it.
Step 6: Verify client connectivity and health
- Test on a handful of devices across different networks home, mobile data, public Wi-Fi.
- Confirm that the VPN connects automatically on startup and reconnects after interruptions.
- Check logs on the RRAS gateway and NPS for any authentication or connection issues.
Client-side configuration: making it automatic on Windows
- Create a VPN connection that uses IKEv2 with certificate authentication.
- Ensure the client machines trust your CA.
- Push the VPN profile through GPO/Intune with “Always On” behavior in the sense of auto-connect settings and on-demand rules.
- You can configure Windows to connect automatically by setting the VPN connection to connect on startup and to reconnect if the connection is dropped.
Cross-platform considerations: macOS, iOS, Android Best edge vpn extension for secure browsing, edge computing, and cross-platform vpn extensions 2025
- macOS: Use the built-in Network preferences or a management tool to push a VPN profile. IKEv2 with certificate-based auth is well-supported. You’ll want to ensure the profile includes the correct server address, EAP/TLS settings, and a trigger to connect automatically when the device starts or wakes.
- iOS: Use an MDM profile to deploy an IKEv2 VPN with On Demand rules so the device auto-connects when it needs to reach corporate resources. Ensure the profile includes necessary app extensions and trusted root CAs.
- Android: Modern Android versions support Always On VPN in the Network & Internet settings or via enterprise mobility management EMM. Configure a per-device or per-user VPN profile with IKEv2 and certificate-based authentication, and enable “Always-on” plus “Block connections without VPN” if your policy allows.
Security best practices and gotchas
- Certificate-based authentication wins: It’s harder to compromise than password-based logins. Issue unique client certs and revoke them when devices are decommissioned.
- Use strong cryptography: IKEv2 with strong ciphers AES-256, SHA-256, PFS and robust CA validation.
- Consider DNS and traffic routing: Route all traffic through VPN for maximum privacy and corporate resource protection, unless you have a clear split-tunnel use case.
- Regularly rotate certificates and keys: Set expiry-aware workflows and automated renewal to avoid sudden disconnects.
- Multi-factor authentication: If possible, combine with device-based or user-based MFA for tighter security.
Performance and reliability tips
- Plan gateway capacity: The VPN gateway must handle concurrent connections and encryption workloads. If you’re growing, scale up or add additional gateways.
- Optimize MTU and fragmentation: Ensure MTU settings are tuned to avoid packet fragmentation, which can cause connection instability.
- Use keep-alives and dead-peer detection: These keep sessions healthy and allow for fast recovery if the tunnel drops.
- Monitor VPN health: Centralized dashboards on the gateway, NPS analytics, and device-level health checks help catch issues before users complain.
Common issues and how to fix them
- Issue: VPN won’t auto-connect on startup
Fix: Verify the profile is set to auto-connect and that the device starts the VPN service early in the boot process. Check the startup scripts or MDM policies. - Issue: Certificate trust errors
Fix: Make sure the client devices trust the root CA and that intermediate certs are in place. Reissue client certs if needed. - Issue: Slow performance
Fix: Check gateway load, network bandwidth, and encryption settings. Consider upgrading hardware or distributing load across multiple gateways. - Issue: DNS leaks
Fix: Push DNS servers to clients or force DNS through VPN. Verify that requests resolve through the VPN DNS. - Issue: Intermittent disconnects
Fix: Enable robust keep-alives, check for network instability, and ensure the gateway and NPS logs don’t show recurring authentication failures. - Issue: Mac/iOS/Android auto-connect not working
Fix: Confirm the MDM profile contains accurate server details and that On Demand rules iOS or Always-On settings Android are properly configured.
