Lab Document: 
<Please login to see the content>
The video walks you through configuration of VPN RADIUS authentication on Cisco ISE 1.2 with AnyConnect Client SSL VPN. We will try to solve the problem of users having to select a VPN group at login by dynamically assigning them to a group-policy via Class RADIUS attribute. We will also attempt to enforce per-user ACL via the Downloadable ACL on ISE. This video is a counterpart of SEC0096 - ACS 5.4 AnyConnect VPN RADIUS Authentication and Authorization.
Part 1 of this video provides overview of the lab setup and completes all required configuration on ISE.

Does this still work if you put an IPN in the middle here? Need to do posturing on laptops. Yes, I know 9.2 code is out but these will be with older 5510 ASAs.

Configuration on the ASA would be the same but instead of using the PSN as the RADIUS server, you need to use the IPN. IPN will act as a RADIUS proxy relaying RADIUS messages between the ASA and PSN and also handle all of the CoA and dACL. 

I have Question.
first of all, we are using IPEP because ASA doesn`t support the COA, ok
regardless the Posture, we are using COA in authorization through VPN, why we don`t use IPEP node ?

- The Question in other words.
why we don`t use IPEP node in the (VPN without Posture) connection although there is ASA and we need COA for authorization. ?

Thanks alot.

Since ASA (as of 9.2) now supports CoA, there is almost no reason to complicate the design with iPEP. Nowaday, iPEP is pretty much strictly used when you deal with non-Cisco device (wireless or VPN). CoA is only needed when you want to switch authorization mid-session which is usually required in posture assessment. If you don't need to posture on VPN, there is not really reason for CoA on ASA or iPEP.

i need example for cisco ise with VPN and use IPEP in bridge mode

Hello labminutes team,

I hope you are fine.
I wanted to ask if it is possible to perform radius authentication and authorization on Cisco ISE 1.4, using cisco ASA and Cisco VPN Client 5.x? Or this function is limited only to anyconnect client?

Thank you for the great work

Absolutely. At the end of the day, it is still RADIUS. ISE does not care if it's SSL or IPSec VPN. Configuration on ISE should be similat if not the same.

Thank you LabMinutes, It worked perfectly with cisco vpn client 5.0

Kind Regards

I have an authorization profile for Group Policy mapped with radius class 25 and name showing under "ASA VPN" . I can see the ASA debug radius for COA and Radius push with new Group policy via authorisation of ISE. BUT ITS NOT GETTING REFLECTED OR CHANGED IN SH VPN-SESS DETAILS ANYCONNECT . ANy idea why its not reflecting for user though its getting pushed from ISE and showing in debugs
