3. IKE/IPsec configuration
4. Dynamic VPN configuration
5. Policy configuration

    Note: The first User Auth (at step 8) is being used to download the configuration and to establish an IKE security association. The second credentials (at this step) is used to establish IPSEC Security association and make the connection. Both the user credentials can be either same or different based on the configuration on the SRX Appliance.



  12. If the user credentials are accepted then the connection is established. The status of the connection shows as ‘Connected’




  13. To verify the connection, go to command prompt and type IPCONFIG /ALL.  Look for the Juniper Network Agent Virtual Adapter.  This is required to successfully access protected resources.  The address is assigned with the Framed-IP-Address and Framed-IP-Netmask attributes on the RADIUS server.
