Este ejemplo de configuración muestra cómo conectar un VPN Client a un PIX Firewall usando comodines, mode-config, el comando sysopt connection permit-ipsec y la autenticación extendida (Xauth).
Para ver la configuración TACACS+ y RADIUS para PIX 6.3 y posteriores, consulte Ejemplo de Configuración de TACACS+ y RADIUS para PIX 6.3 y PIX/ASA 7.x.
El cliente VPN admite el estándar de cifrado avanzado (AES) como algoritmo de cifrado en Cisco VPN Client versión 3.6.1 y posteriores y con PIX Firewall 6.3. VPN Client soporta tamaños de clave de 128 bits y 256 bits solamente. Para obtener más información sobre cómo configurar AES, consulte Cómo Configurar Cisco VPN Client a PIX con AES.
Consulte Ejemplo de Configuración de Autenticación de PIX/ASA 7.x y Cisco VPN Client 4.x para Windows con Microsoft Windows 2003 IAS RADIUS para configurar la conexión VPN de acceso remoto entre un Cisco VPN Client (4.x para Windows) y el PIX 500 Series Security Appliance 7.x usando un servidor RADIUS de Servicio de Autenticación de Internet (IAS) de Microsoft Windows 2003.
Consulte Ejemplo de Configuración de IPsec entre un Concentrador VPN 3000 y un Cliente VPN 4.x para Windows que usa RADIUS para la Autenticación de Usuario y la Configuración de Contabilización para establecer un túnel IPsec entre un Concentrador VPN 3000 de Cisco y un Cliente VPN 4.x de Cisco para Windows que usa RADIUS para la autenticación y contabilidad de usuario.
Consulte Configuración de IPsec entre un Cisco IOS Router y un Cisco VPN Client 4.x para Windows Usando RADIUS para la Autenticación de Usuario para configurar una conexión entre un router y Cisco VPN Client 4.x usando RADIUS para la autenticación de usuario.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
El comando sysopt connection permit-ipsec permite implícitamente que cualquier paquete que provenga de un túnel IPsec omita la verificación de un comando access-list, conduit o access-group asociado para las conexiones IPsec. Xauth autentica al usuario IPSec hacia un servidor externo TACACS+ o RADIUS. Además de la clave previamente compartida comodín, el usuario debe proporcionar un nombre de usuario/contraseña.
Un usuario con un cliente VPN recibe una dirección IP de su ISP. Esto se reemplaza por una dirección IP del conjunto de direcciones IP en el PIX. El usuario puede acceder a todo el contenido del escudo de protección, incluidas las redes. Los usuarios que no ejecutan VPN Client pueden conectarse solamente al servidor web usando la dirección externa proporcionada por la asignación estática.
En esta sección encontrará la información para configurar las funciones descritas en este documento.
Nota: Use la Command Lookup Tool (sólo clientes registrados) para obtener más información sobre los comandos utilizados en este documento.
En este documento, se utiliza esta configuración de red:
Los hosts de Internet que acceden al servidor web utilizando la dirección IP global 192.168.1.1 se autentican incluso si no se establece una conexión VPN. Este tráfico no está cifrado.
Los clientes VPN pueden acceder a todos los hosts de la red interna (10.89.129.128/25) una vez que se haya establecido su túnel IPsec. Todo el tráfico del VPN Client al PIX Firewall está cifrado. Sin un túnel IPsec, sólo pueden acceder al servidor web a través de su dirección IP global, pero aún así se les requiere autenticarse.
Los clientes VPN vienen de Internet y sus direcciones IP no se conocen de antemano.
Este documento usa estas configuraciones.

La sintaxis del comando para agregar contabilidad es:
aaa accounting include acctg_service inbound|outbound l_ip l_mask [f_ip f_mask] server_tag
Por ejemplo, en la configuración de PIX, se agrega este comando:
aaa accounting include any inbound 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 AuthInbound
Nota: El comando sysopt connection permit-ipsec, no el comando sysopt ipsec pl-compatible, es necesario para que la contabilidad Xauth funcione. La cuenta Xauth no funciona sólo con el comando sysopt ipsec pl-compatible. La contabilización Xauth es válida para conexiones TCP, no para ICMP o UDP.
