RRAS IPsec Configuration

Applies To: Windows Server 2008 R2

For L2TP-based virtual private networking (VPN) connections, a certificate infrastructure is required to issue computer certificates used to negotiate authentication for Internet Protocol security (IPsec). If a computer certificate required for IPsec is not available, the connection will fail.



Event ID Source Message



Failed to apply IP security on port: %1 because of error: %2. No calls will be accepted to this port.



A certificate could not be found. Connections that use the L2TP protocol over IPsec require the installation of a machine certificate also known as a computer certificate. No L2TP calls will be accepted.
