Do you have something like?

access-list inside_nat0_outbound extended permit ip 192.168.10.0 255.255.255.0

nat (inside) 0 access-list inside_nat0_outbound

Yes, I have this...

when I have local-user on ASA ; it works.

But how could the traffic forward to ACS Server...

Are you sure, you have something like this on configuration,

aaa-server RADIUS-SERVER protocol radius

aaa-server RADIUS-SERVER () host

tunnel-group PAK-TEL general-attributes

authentication-server-group RADIUS-SERVER

Assuming that you are using Radius protocol for authentication and ACS is configured accordingly.

Try to use following test command to ensure that authentication is working against the ACS server,

test aaa-server authentication host

e.g.,

test aaa-server authentication RADIUS host 1.2.3.4

Thanks.

I dont see any failed/passed info under Reports-logging on ACS..

On ACS the following is done

ASA added under AAA client with shared key

Radius authentication

rename group5 on ACS as PAK-TEL

No Luck so far...

Renaming Group to PAK-TEL is not required, its only for your management comfort only.

One question, are you able to authentication using the current ACS against any other device ? Or is ASA is the only one that you are trying to authenticate. Could be that ACS is not configured properly, by that I mean "Proxy Distribution Table" is not configured properly.

If this is the first time you are trying to authenticate on ACS, then please enable Passed Reports as it is disabled by default.

The very first thing that should be successful, in order to get VPN users authenticated is, to ensure that the "test aaa...." command is successful from the ASA, if that does not succeed, then no point in testing using VPN client.

Make sure that nothing is blocking the Radius traffic in between i.e b/w ASA and ACS.

What is the result of the test command, is it,

"ERROR: Authentication Server not responding: No error" ?

Or something else ?
