Chapter 4 Remote Access VPN Services
Creating Remote Access VPN Policies
Table 
| 
 | Field Name | Type | Instructions | 
 | |||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | Name | text box | Enter a name for the policy. However, the name cannot contain spaces because it is | ||||
| 
 | 
 | 
 | 
 | 
 | used as the VPN group name. | ||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | Owner | radio button | Click Customer > Select and choose the customer for which the remote access VPN | ||||
| 
 | 
 | 
 | 
 | and Select | is intended. When you click Customer > Select, the Customer for IPsec Policy dialog | ||
| 
 | 
 | 
 | 
 | button | box appears. Click the button next to the customer you want to select and click Select | ||
| 
 | 
 | 
 | 
 | 
 | (to choose that customer), or click Cancel to exit the dialog box without saving | ||
| 
 | 
 | 
 | 
 | 
 | changes. Both return you to the main page. | ||
| 
 | 
 | 
 | 
 | 
 | Do not select Global. It is important to associate remote access policies with a | ||
| 
 | 
 | 
 | 
 | 
 | specific customer because many remote access VPN parameters are | ||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | Encryption Policy | Select button | Choose the name of an encryption policy you created in previous steps by clicking | ||||
| 
 | 
 | 
 | 
 | 
 | Select. The encryption policy specifies the IKE and IPsec proposal parameters for the | ||
| 
 | 
 | 
 | 
 | 
 | IPsec VPN and determines the level of encryption used in the IPsec VPN tunnels. | ||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | Group Type | Select the policy type. An internal group is configured on the VPN device while an | |||||
| 
 | 
 | 
 | 
 | list | external group is configured on an external AAA server. | ||
| 
 | 
 | 
 | 
 | 
 | • Internal – Group attributes are on the target device. If the user profiles and group | ||
| 
 | 
 | 
 | 
 | 
 | attributes are maintained on the CPE device itself, select Internal. | ||
| 
 | 
 | 
 | 
 | 
 | • External – Group attributes are obtained from a AAA Server. If the user profiles | ||
| 
 | 
 | 
 | 
 | 
 | and group attributes are maintained on a AAA Server, select External. | ||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | Group Password | text box | Required when you select Internal for the Group Type field. Enter the password | ||||
| 
 | 
 | 
 | 
 | 
 | (IKE preshared key) for the group. The policy name and password are very important | ||
| 
 | 
 | 
 | 
 | 
 | because they are the group name and password that remote users must use when | ||
| 
 | 
 | 
 | 
 | 
 | connecting through the Cisco VPN Client. | ||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | Confirm Password | text box | |||||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | XAuth | checkbox | Check to enable IKE Extended Authentication (XAuth). | ||||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | XAuth Timeout | text box | Enter the idle timeout value for XAuth. The range is from 5 to 90 seconds. The default | ||||
| 
 | 
 | 
 | 
 | 
 | value is 5 seconds. | ||
| 
 | 
 | 
 | 
 | 
 | |||
| 
 | Use Mode | checkbox | Mode Configuration is also known as the ISAKMP Configuration Method or | ||||
| 
 | Configuration | 
 | Configuration Transaction. Specifically, when enabled, this option exchanges | ||||
| 
 | 
 | 
 | 
 | 
 | configuration parameters with the client while negotiating Security Associations | ||
| 
 | 
 | 
 | 
 | 
 | (SAs). | ||
| 
 | 
 | 
 | 
 | 
 | Check the Mode Configuration checkbox to use Mode Configuration with the IPsec | ||
| 
 | 
 | 
 | 
 | 
 | clients in this group. You must enable Mode Configuration for IPsec clients because | ||
| 
 | 
 | 
 | 
 | 
 | IPsec uses Mode Configuration to pass all configuration parameters to the client. | ||
| 
 | 
 | 
 | 
 | 
 | Otherwise, these parameters are not passed to the client. Also, you must check this | ||
| 
 | 
 | 
 | 
 | 
 | box to use split tunneling. | ||
| 
 | 
 | 
 | 
 | 
 | Uncheck the box if you are using L2TP over IPsec as your tunneling protocol. | ||
| 
 | 
 | 
 | 
 | 
 | Note The Cisco VPN Client supports Mode Configuration, but other IPsec clients | ||
| 
 | 
 | 
 | 
 | 
 | may not. For example, the Microsoft Windows 2000 IPsec client does not | ||
| 
 | 
 | 
 | 
 | 
 | support Mode Configuration. (The Windows 2000 client uses the PPP layer | ||
| 
 | 
 | 
 | 
 | 
 | above L2TP to receive its IP address from the VPN Concentrator.) If you are | ||
| 
 | 
 | 
 | 
 | 
 | using other client software packages, check for compatibility in the | ||
| 
 | 
 | 
 | 
 | 
 | documentation for your client software before using this option. | ||
