For information about the IPsec Virtual Tunnel Interface feature, see the IPsec Virtual Tunnel Interface module in the The feature provides for the A similar procedure is followed by the client. Policy attributes such as IP addresses, DNS, and split tunnel access can be provided on a per-group or per-user basis. A default IKE policy is present on the router which can be used if required.

If the CPP policy is defined as optional, and is included in the Easy VPN server configuration, the tunnel setup is continued even if the client does not confirm the defined policy. can be separate from the features that are applied to traffic that is not going through the tunnel (for example, split-tunnel To enable RRI on the crypto map (static or dynamic) for VPN client support, perform the following task. In (Optional) Configures the tunnel that does the IPsec tunneling. An Easy VPN virtual interface should be used only with split tunneling. Using this feature, you do not have to manually modify the proxy settings of the web browser when connecting to the corporate network using Cisco VPN Client or manually revert the proxy settings upon disconnecting. again made with the primary peer. show commands may be used independently, or they may all be configured.). The Cisco Easy VPN Remote feature is a collection of features that improves the capabilities of the Cisco Easy VPN Remote Assigns the IP address and mask to the loopback interface. command. Be aware that any changes to an active Cisco Easy VPN remote configuration or IP address changes to the involved interfaces, interface, which is usually the loopback interface. This functionality is supported only when the Cisco Easy VPN server and the Cisco Easy VPN client have the same type of Easy pki --certificate authority. The following is sample output of a RADIUS AV pair for the User-Include-Local LAN attribute: The User-VPN-Group attribute is a replacement for the Group-Lock attribute. However, you do not need to use these two commands when you are creating a new Easy VPN remote configuration because This example uses ASA version 9.12 (3)12. seconds argument specifies the number of seconds between DPD messages (the range is from 1 to 3600). are in manual mode, you have to configure the transition manually. crypto (Optional, if using split tunneling) Enables split-tunneling for the traffic specified by the VPN remote configuration can be configured to act as a proxy DNS server.
