How to Configure the VPN 3000 for Windows 2000 Support

Follow the instructions provided below to configure the VPN 3000 Concentrator.

1. Go to Configuration > User Management > Groups and click Add Group.

   1. Enter a Group Name and a Password. The Group Name must be the same as the Organizational Unit (OU) field in the Windows 2000 Client's digital certificate. The Password is not used so you can set it to anything you choose.

   2. On the General tab, select Tunneling Protocols = L2TP over IPSec.

   3. On the IPSec tab, select IPSec SA = ESP-L2TP-TRANSPORT, Authentication = None, and Mode Configuration = None (unchecked).

2. Go to Configuration > System > Tunneling Protocols > IPSec > IKE Proposals and activate the IKE-3DES-MD5-RSA or IKE-3DES-SHA-DSA proposal depending on the client certificate type (RSA or DSA). Move the proposal to the top of the list.

3. Go to Configuration > Policy Management > Traffic Management > Security Associations. Select ESP-L2TP-TRANSPORT and click Modify. Under Digital Certificate, click the drop-down menu and select the certificate you created for the VPN Concentrator.
