Autenticação e tarifação RADIUS e TACACS+ e, até certo ponto, autorização são feitas para túneis de Cliente de Hardware Cisco Secure VPN Client 1.1 e Cisco VPN 3000 2.5 que terminam no PIX. As alterações no PIX 5.2 e na autenticação estendida posterior (Xauth) em relação às versões anteriores que incluem o suporte à lista de acesso de autenticação, autorização e contabilização (AAA - Authentication, Authorization, and Accounting) para controlar quais usuários autenticados podem acessar e suportar a terminação Xauth do Cisco VPN 3000 Client 2.5. O comando vpn group split-tunneling permite que o VPN 3000 Client se conecte à rede dentro do PIX, bem como a outras redes (por exemplo, a Internet) ao mesmo tempo. No PIX 5.3 e posterior, a alteração de AAA em relação às versões anteriores do código é que as portas RADIUS são configuráveis. No PIX 6.0, o suporte para o VPN Client 3.x é adicionado. Isso requer o grupo Diffie-Hellman 2.
Não existem requisitos específicos para este documento.
As informações neste documento são baseadas nestas versões de software e hardware:
Software PIX Versão 5.2.1
Cisco Secure VPN Client 1.1
Cisco VPN 3000 2.5 Client ou VPN Client 3.x
Observação: o Cisco VPN Client versão 3.0.x não funciona com versões do PIX anteriores à 6.0. Consulte Hardware e VPN Clients da Cisco que Suportam IPsec/PPTP/L2TP para obter mais informações.
As informações neste documento foram criadas a partir de dispositivos em um ambiente de laboratório específico. Todos os dispositivos utilizados neste documento foram iniciados com uma configuração (padrão) inicial. Se a sua rede estiver ativa, certifique-se de que entende o impacto potencial de qualquer comando.
Consulte as Convenções de Dicas Técnicas da Cisco para obter mais informações sobre convenções de documentos.
O software PIX Firewall versão 6.2 suporta o download de Listas de Controle de Acesso (ACLs - Access Control Lists) para o PIX Firewall a partir de um Servidor de Controle de Acesso (ACS - Access Control Server). Isso permite a configuração de ACLs por usuário em um servidor AAA para fornecer autorização de ACL por usuário. Em seguida, é possível fazer o download através do ACS para o PIX Firewall. Este recurso é suportado apenas em servidores RADIUS. Ele não é suportado para servidores TACACS+.
Conclua estas etapas de depuração:
Verifique se a configuração do PIX Xauth funciona antes de adicionar a autenticação AAA.
Se você não conseguir passar o tráfego antes de implementar o AAA, não poderá fazê-lo posteriormente.
Ative algum tipo de registro no PIX:
Não emita o comando logging console debugging em um sistema com carga pesada.
O comando logging buffered debugging pode ser emitido. Em seguida, emita o comando show logging.
O registro também pode ser enviado a um servidor System Message Log (syslog) e examinado.
Ativar depuração no TACACS+ ou nos servidores RADIUS. Todos os servidores possuem esta opção.
debug crypto ipsec sa— Este comando debug exibe eventos IPsec.
debug crypto isakmp sa— Este comando debug exibe mensagens sobre eventos do Internet Key Exchange (IKE).
debug crypto isakmp engine— Este comando debug exibe mensagens sobre eventos IKE.
Ative o Log Viewer para ver as depurações do lado do cliente no Cisco Secure 1.1 ou no VPN 3000 Client 2.5.

Os usuários parciais noacl, 3000full e 3000partial precisam apenas de um nome de usuário e uma senha no Cisco Secure ACS para Windows. O usuário pixb precisa de um nome de usuário, uma senha, um shell/exec marcado no grupo, uma ACL marcada e 115 na caixa.
user = noacl{ password = clear "********" } user = pixb{ password = clear "********" radius=Cisco { reply_attributes= { 9,1="acl=115" } } } user = 3000full{ password = clear "********" } user = 3000partial{ password = clear "********" }
RADIUS/Cisco é o tipo de dispositivo. Os usuários parciais noacl, 3000full e 3000partial precisam apenas de um nome de usuário e uma senha no Cisco Secure ACS para Windows. O usuário pixb precisa de um nome de usuário, uma senha e uma marca e acl=115 na caixa retangular Cisco/RADIUS onde consta 009\001 AV-Pair (específico do fornecedor).
Observação: você precisa do atributo de fornecedor para a ACL. O atributo 11, filter-id, não é válido. Este problema recebeu a ID de bug da Cisco CSCdt50422 (somente clientes registrados) . É corrigido no PIX Software Release 6.0.1.
noacl Password= "noacl" pixb Password= "pixb" cisco-avpair = "acl=115" 3000full Password= "3000full" 3000partial Password= "3000partial"
Alguns servidores RADIUS utilizam portas RADIUS diferentes de 1645/1646 (geralmente 1812/1813). No PIX 5.3 e posterior, as portas de autenticação e contabilização RADIUS podem ser alteradas para portas diferentes das portas 1645/1646 padrão com estes comandos:
aaa-server radius-authport #
aaa-server radius-acctport #
Neste exemplo, todos os três VPN Clients são autenticados com Xauth. No entanto, os VPN Clients podem acessar somente a rede dentro do PIX, pois o tunelamento dividido não está em uso. Consulte Como autenticar Xauth com grupos VPN para obter mais informações sobre split-tunneling. As ACLs passadas do servidor AAA aplicam-se a qualquer VPN Clients. Neste exemplo, o objetivo é que o usuário noacl se conecte e obtenha todos os recursos dentro do PIX. O usuário pixb se conecta, mas como a ACL 115 é passada do servidor AAA durante o processo Xauth, o usuário só pode chegar a 10.1.1.40. O acesso a 10.1.1.41 e a todos os outros endereços IP dentro dele é negado.
Observação: o PIX Software Release 6.0 é necessário para suporte ao VPN Client 3.0.

Neste exemplo, o VPN 3000 Client 2.5 ou o VPN Client 3.0 pode ser autenticado com Xauth e o tunelamento dividido está em vigor. Devido à associação ao Grupo VPN, uma ACL é passada do PIX para o VPN 3000 Client. Ele especifica que somente a rede dentro do PIX tem um túnel criptografado. Outro tráfego (talvez para a Internet) não é criptografado.
Neste exemplo, um VPN Client, com o nome de usuário 3000full (no servidor AAA), no grupo vpn3000-all (no PIX) acessa toda a rede 10.1.1.X dentro do PIX ao mesmo tempo que a Internet. O cliente VPN recebe informações de wins-server, dns-server e domain-name. O outro VPN Client, com o nome de usuário 3000partial (no servidor AAA), no grupo vpn3000-41 (no PIX) acessa apenas um endereço IP dentro da rede (10.1.1.40) em virtude do perfil do grupo. Esse VPN Client não recebe informações de wins e dns-server, mas ainda faz o split-tunneling.
Observação: o PIX Software Release 6.0 é necessário para suporte ao VPN Client 3.0.
Conclua estes passos:
Observação: a configuração do VPN 2.5 ou 3.0 Client depende do usuário envolvido.
Selecionar opções > Propriedades > Autenticação.
O nome do grupo e a senha do grupo correspondem ao nome do grupo no PIX como em: vpngroup vpn3000-all password ******** ou vpngroup vpn3000-41 password ********. O nome do host é 172.18.124.157.
Clique em Conectar.
Quando a janela de Xauth for exibida, digite o nome de usuário e a senha usados no servidor de AAA.
Neste exemplo, quando o usuário 3000full é autenticado, ele coleta as informações do grupo vpn3000-all. O usuário 3000partial coleta as informações do grupo vpn3000-41. A janela mostra Negotiating security profiles e Your link is now secure.
O usuário 3000full usa a senha para o grupo vpn3000-all. A lista de acesso 108 é associada a esse grupo para fins de separação de túneis. O túnel é formado para a rede 10.1.1.x. O tráfego flui sem criptografia para dispositivos que não estão na lista de acesso 108 (por exemplo, a Internet). Isso é tunelamento dividido.
Esta é a saída da janela de status de conexão do VPN Client para o usuário 3000full:
Network Mask key 10.1.1.0 255.255.255.0 key 172.18.124.157 255.255.255.255
O usuário 3000partial usa a senha para o grupo vpn3000-41. A lista de acesso 125 é associada a esse grupo para fins de separação de túneis. O túnel é formado para o dispositivo 10.1.1.41. O tráfego flui sem criptografia para dispositivos que não estão na lista de acesso 125 (por exemplo, a Internet). No entanto, o tráfego não flui para o dispositivo 10.1.1.40 porque esse tráfego não é roteável. Ele não está especificado na lista de túneis de criptografia.
Esta é a saída da janela de status da conexão do VPN Client para o usuário 3000partial:
Network Mask key 10.1.1.41 255.255.255.255 key 172.18.124.157 255.255.255.255
Observação: o Cisco Secure VPN Client 1.1 não funciona com isso porque não há chave de Internet Security Association and Key Management Protocol (ISAKMP). Adicione o comando isakmp key ******** address 0.0.0.0 netmask 0.0.0.0 para fazer com que todos os VPN Clients funcionem.

Estes comandos são necessários para configurar o Xauth local para a conexão do VPN Client:
aaa-server server-tag protocol local
crypto map map-name client authentication aaa-server-name
Execute o comando username para definir usuários locais no PIX.
Para usar o banco de dados de autenticação de usuário do PIX Firewall local, insira LOCAL para o parâmetro server-tag do comando aaa-server. O comando aaa-server é emitido com o comando crypto map para estabelecer uma associação de autenticação de modo que os clientes VPN sejam autenticados quando acessarem o PIX Firewall.
Esta é a sintaxe do comando para adicionar relatório:
aaa accounting acctg_service|except inbound|outbound|if_name local_ip local_mask foreign_ip foreign_mask tacacs+|radius ;
ou (novo no ponto 5.2):
aaa accounting include acctg_service inbound|outbound match server_tag
Na configuração do PIX, este é o comando adicionado:
a contabilização aaa inclui qualquer entrada 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 AuthInbound ;
ou (novo no ponto 5.2):
access-list 150 permit ip any any aaa accounting match 150 outside 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 contabilização Xauth é válida para conexões TCP.
