By default, all the traffic passes through the VPN tunnel if the split tunnel is not configured. This access list consists of the destination networks that can be accessed through the VPN tunnel. (Optional) Configure a standard access list to be used for the split tunnel. You can refer to Certificate Enrollment for a PKI for more details on the certificate creation.Ĥ. Create a Trustpoint in order to install the identity certificate, if not already present for local authentication. Configure the RADIUS server as aaa authentication and authorization as local.Īaa group server radius FlexVPN_auth_serverĪaa authentication login FlexVPN_auth group FlexVPN_auth_serverĪaa authorization network FlexVPN_authz localģ. The IP address of the RADIUS server must be the IP of the Duo Authentication Proxy.Īddress ipv4 10.197.243.97 auth-port 1812 acct-port 1813Ģ. Configuration Steps on C8000V (VPN Headend)ġ. In order to complete the configuration, take into consideration these sections. If successful, the An圜onnect connection is established.Duo authentication proxy receives the authentication response.
The Duo service then authenticates the user, depending on the secondary authentication method (push, phone call, passcode).Once the primary authentication is successful then the Duo authentication proxy requests secondary authentication via the Duo server.The authentication response is sent back to the Authentication Proxy.Duo Authentication Proxy then sends the primary request to the Active Directory or RADIUS server.The C8000V sends an authentication request to the Duo Authentication Proxy.The user initiates a RAVPN connection to the C8000V and provides a username and password for Primary Authentication.Flow DiagramĪuthentication Flow Diagram Communication Process The Duo Authentication Proxy server also sends an additional authentication in the form of a push notification to the mobile device of the user.
