IKEv2 requires the VPNUK root certificate to be installed in Windows. Download the certificate and install it using the Microsoft Management Console (MMC).

mmcand press Enter - In MMC: File → Add/Remove Snap-in → Certificates → Add → Computer account → Local Computer → OK
- Expand Certificates (Local Computer) → Trusted Root Certification Authorities
- Right-click Certificates → All Tasks → Import
- Browse to the downloaded
vpnuk.crtfile and import it - Ensure it is placed in Trusted Root Certification Authorities and click Finish
Part 2 — Add the VPN Connection
- Open Control Panel → Network and Internet → Network and Sharing Centre
- Click Set up a new connection or network
- Select Connect to a workplace → Use my Internet connection (VPN)
- Enter your VPNUK server address (from Client CP or Welcome email). Name it VPNUK IKEv2. Click Create
- Go to Change adapter settings, right-click the VPNUK connection → Properties → Security
- Set Type of VPN to IKEv2
- Set Authentication → Use Extensible Authentication Protocol (EAP) → Microsoft: Secured password (EAP-MSCHAP v2)
- Click OK. Right-click the connection → Connect. Enter your VPN username and password
Connected! Your internet traffic is now encrypted and routed through VPNUK.
Troubleshooting
