Este exemplo de configuração demonstra como conectar um VPN Client a um PIX Firewall usando curingas, mode-config, o comando sysopt connection permit-ipsec e autenticação estendida (Xauth).
Para ver a configuração TACACS+ e RADIUS para PIX 6.3 e posterior, consulte TACACS+ e RADIUS para PIX 6.3 e PIX/ASA 7.x Configuration Example.
O VPN Client suporta AES (Advanced Encryption Standard) como um algoritmo de criptografia no Cisco VPN Client versão 3.6.1 e posterior e com PIX Firewall 6.3. O VPN Client suporta tamanhos chave de 128 bits e 256 bits apenas. Para obter mais informações sobre como configurar AES, consulte Como configurar o Cisco VPN Client para PIX com AES.
Consulte Exemplo de Configuração de Autenticação do PIX/ASA 7.x e do Cisco VPN Client 4.x para Windows com o Microsoft Windows 2003 IAS RADIUS para configurar a conexão VPN de acesso remoto entre um Cisco VPN Client (4.x para Windows) e o PIX 500 Series Security Appliance 7.x usando um Microsoft Windows 2003 Internet Authentication Service (IAS) Servidor RADIUS.
Consulte IPsec Between a VPN 3000 Concentrator and a VPN Client 4.x for Windows using RADIUS for User Authentication and Accounting Configuration Example para estabelecer um túnel IPsec entre um Cisco VPN 3000 Concentrator e um Cisco VPN Client 4.x for Windows usando RADIUS para autenticação e tarifação do usuário.

O comando sysopt connection permit-ipsec permite implicitamente que qualquer pacote proveniente de um túnel IPsec ignore a verificação de uma lista de acesso associada, conduit ou grupo de acesso para conexões IPsec. Xauth autentica o usuário IPSec em um servidor TACACS+ ou RADIUS externo. Além da chave pré-compartilhada curinga, o usuário deve fornecer um nome de usuário/senha.
Um usuário com um cliente VPN recebe um endereço IP de seu ISP. Isso é substituído por um endereço IP do pool de endereços IP no PIX. O usuário tem acesso a tudo o que está dentro do firewall, incluindo as redes. Os usuários que não executam o VPN Client podem se conectar somente ao servidor Web usando o endereço externo fornecido pela atribuição estática.
Nesta seção, você encontrará informações para configurar os recursos descritos neste documento.
Nota:Use a Command Lookup Tool (somente clientes registrados) para obter mais informações sobre os comandos usados neste documento.
Este documento utiliza a seguinte configuração de rede:
Os hosts da Internet que acessam o servidor Web usando o endereço IP global 192.168.1.1 são autenticados mesmo que uma conexão VPN não esteja estabelecida. Este tráfego não está criptografado.
Os VPN Clients podem acessar todos os hosts na rede interna (10.89.129.128 /25) assim que o túnel IPsec for estabelecido. Todo o tráfego do VPN Client para o PIX Firewall é criptografado. Sem um túnel IPsec, eles só podem acessar o servidor Web por meio de seu endereço IP global, mas ainda são necessários para autenticar.
Os clientes de VPN surgem da Internet e seus endereços de IP não são conhecidos com antecedência.
Este documento utiliza estas configurações.

A sintaxe do comando para adicionar relatório é:
aaa accounting include acctg_service inbound|outbound l_ip l_mask [f_ip f_mask] server_tag
Por exemplo, na configuração do PIX, este comando é adicionado:
aaa accounting include any inbound 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 AuthInbound
Observação: o comando sysopt connection permit-ipsec, não o comando sysopt ipsec pl-compatible, é necessário para que a contabilidade Xauth funcione. O relatório Xauth não funciona apenas com o comando sysopt ipsec pl-compatible. A contabilidade Xauth é válida para conexões TCP, não para ICMP ou UDP.
