Hello,

I've spent hours trying to make heads or tails of the example: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a00806de37e.shtml

XX for privacy

Any direction would be greatly appreciated.

Thanks for the tip, http outside turned off now!

Looks like I've got some more noodling to do, don't recall how to setup a local database.  Its been almost 10 years since I've configured a pix, beleive or not I used to work for Cisco in Austin in QA security appliances.  Back when it was IDS, fun stuff!

Cheers,

Troy

To configure the username and password, just configure the following:

username password

Then to assign the vpn group to use local authentication:

tunnel-group vpn general-attributes

     authentication-server-group LOCAL

========================================================

BTW, just look at your config again, and radius authentication server is not assigned to your vpn group, so before you try the above, can you try the following:

tunnel-group vpn general-attributes

     authentication-server-group (inside) vpn

And test to see if VPN Client connection with IAS authentication works.

========================================================

You might want to remove this too:

tunnel-group DefaultRAGroup general-attributes
     no  authentication-server-group (outside) vpn

Ok, I did the following:

1.) executed:

tunnel-group vpn general-attributes

      authentication-server-group (inside) vpn

2.) I added a user to local db.

3.) executed:

tunnel-group DefaultRAGroup general-attributes
     no   authentication-server-group (outside) vpn

Here is the behavior now... When attempting to login via the VPN Client, I get prompted for uname and pass.  When I enter an account that we know works on the IAS radius server I get prompted 3 times before it fails on the third attempt.

When I try with the locally added db account, I only get one try and it fails immediately.

You would need to change the authentication depending on which you are testing.

If you are going to test authenticating to IAS radius, then you would need to have the following configured:

tunnel-group vpn general-attributes

      authentication-server-group (inside) vpn

If you are going to test authenticating to local database, then the following is required:

tunnel-group vpn general-attributes

      authentication-server-group LOCAL

Please kindly make sure that you only have 1 or the other when you are configuring it. To check the current configuration, issue: sh run tunnel-group vpn
