The intention of this blog post is to describe the steps to configure certificate authentication for FlexVPN on a Cisco IOS router. This post will not describe all the steps to enrol for a certificate or all the steps to configure FlexVPN, refer to the previous blog posts list below.
The configuration used is based on the FlexVPN sVTI blog post below and has successfully enrolled for certificates on all routers. VPN connectivity has been established using PSK, the configuration below will convert from PSK to certificate authentication.
Requesting a certificate on Cisco IOS router using SCEP or manual enrolment
Configuring FlexVPN VTI and Hub-and-Spoke on Cisco routers
Configure FlexVPN for Certificate authentication
All certificates in this FlexVPN lab are signed by the CA called lab-PKI-CA
Run the command show crypto pki certificates to identify the issuer, in this instance lab-PKI-CA

The intention of this blog post is to describe how to configure a Cisco IOS router to request a certificate from a Microsoft SCEP (NDES) server to use for VPN authentication. A Windows Server must be configured as a Certificate Authority and with “Network Device Enrollment Service”. In the lab a Windows 2008 R2 server is configured as a Domain Controller, CA and NDES server – in production these roles would ideally located on separate servers.
Windows Server Configuration
