Esse documento demonstra como formar um túnel de IPsec com chaves pré-compartilhadas para unir duas redes privadas:
Uma rede privada dentro do Cisco VPN 3000 Concentrator (192.168.1.x).
Uma rede privada dentro do firewall Checkpoint 4.1 (10.32.50.x ).
Supõe-se que o tráfego de dentro do VPN Concentrator e de dentro do Checkpoint para a Internet (representado neste documento pelas redes 172.18.124.x) flua antes do início desta configuração.
Não existem requisitos específicos para este documento.
As informações neste documento são baseadas nestas versões de software e hardware:
VPN 3000 Concentrator
Versão do software do VPN 3000 Concentrator 2.5.2.F
Checkpoint 4.1 Firewall
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.
Este documento utiliza a seguinte configuração de rede:
Consulte as Convenções de Dicas Técnicas da Cisco para obter mais informações sobre convenções de documentos.
Conclua estas etapas para configurar o VPN 3000 Concentrator.
Selecione Configuration > System > Tunneling Protocols > IPSec > IKE Proposals > Modify para criar uma proposta de Internet Key Exchange (IKE) chamada "des-sha" com hash Secure Hash Algorithm (SHA), Data Encryption Standard (DES) e Diffie-Hellman Group 1. Deixe Time Lifetime (Tempo de vida) como o padrão 86400 segundos.
Observação: o intervalo válido para o tempo de vida de IKE do VPN Concentrator é de 60 a 2147483647 segundos.
Selecione Configuration (Configuração) > System (Sistema) > Tunneling Protocols (Protocolos de Tunelamento) > IPSec > IKE Proposals (Propostas IKE). Selecione "des-sha" e clique em Activate para ativar a proposta IKE.
Selecione Configuration > System > Tunneling Protocols > IPSec LAN-to-LAN > Add (Configuração > Sistema > Protocolos de Canalização > IPSec LAN para LAN > Adicionar).
Configure um túnel IPsec chamado "to_checkpoint" com o endereço do ponto de verificação como o peer. Para a chave pré-compartilhadas, insira a chave real. Em Authentication (Autenticação), selecione ESP/SHA/HMAC-160 e DES-56 for Encryption (DES-56 para criptografia). Insira a proposta IKE (“des-sha” neste exemplo) e as redes local e remota.
Selecione Configuração > Gerenciamento de Política > Gerenciamento de Tráfego > Associações de Segurança > Modificar. Verifique se Perfect Forward Secrecy está Disabled e deixe IPsec Time Lifetime no valor padrão de 2800 segundos.
Observação: o intervalo válido para o tempo de vida de IPsec do VPN Concentrator é de 60 a 2147483647 segundos.
Salve a configuração.
Conclua estas etapas para configurar o Firewall do Checkpoint 4.1.
Como os tempos de vida padrão de IKE e IPsec diferem entre fornecedores, selecione Properties > Encryption para definir os tempos de vida do ponto de verificação para concordar com os padrões do VPN Concentrator.
O tempo de vida IKE padrão do VPN Concentrator é de 86400 segundos (=1440 minutos).
O tempo de vida padrão do IPsec do VPN Concentrator é de 28800 segundos.
Selecione Gerenciar > Objetos de rede > Novo (ou Editar) > Rede para configurar o objeto para a rede interna ("cpinside") por trás do ponto de controle. Isso deve concordar com a "Rede remota" no VPN Concentrator.
Selecione Manage > Network objects > Edit para editar o objeto do ponto final do gateway ("RTPCPVPN" Checkpoint) que o VPN Concentrator tem em seu parâmetro Peer.
Em Local, selecione Interno. Para Tipo, selecione Gateway. Em Modules Installed (Módulos instalados), marque VPN-1 & FireWall-1 e Management Station.
Selecione Manage > Network objects > New (or Edit) > Network para configurar o objeto para a rede externa ("inside_cisco") atrás do VPN Concentrator. Isso deve concordar com a rede "Local" no VPN Concentrator.
Selecione Manage > Network objects > New > Workstation para adicionar um objeto para o gateway do VPN Concentrator externo ("cisco_endpoint"). Esta é a interface "Pública" do VPN Concentrator.
Em Local, selecione Externo. Para Tipo, selecione Gateway.
Observação: Não marque a caixa de seleção VPN-1/FireWall-1.
Selecionar Manage > Network objetct > Edit para editar o ponto final do gateway do ponto de controle (chamado "RTPCPVPN") na guia VPN. Em Domain, selecione Other e, em seguida, selecione o lado interno da rede de ponto de controle (chamado “cpinside”) a partir da lista suspensa. Sob esquemas de criptografia definidos, selecione IKE e clique em Editar.
Altere as propriedades de IKE para a criptografia DES para concordar com o DES-56 e o Algoritmo de Criptografia no Concentrador VPN.
Altere as propriedades de IKE para hash SHA1 para concordar com o algoritmo SHA/HMAC-160 no VPN Concentrator.
Desative o Modo assertivo.
Marque Suporta sub-redes.
Marque Pre-Shared Secret em Authentication Method (Método de autenticação). Isso está de acordo com o Modo de autenticação do VPN Concentrator, Chaves pré-compartilhadas.
Clique em Edit Secrets para definir a chave pré-compartilhada para concordar com a chave pré-compartilhada real do VPN Concentrator.
isakmp key key address address netmask netmask
Selecione Gerenciar > Objetos de rede > Editar para editar a guia VPN “cisco_endpoint”. Em Domain, selecione Other e, em seguida, selecione o interior da rede Cisco (chamado "inside_cisco"). Sob esquemas de criptografia definidos, selecione IKE e clique em Editar.
Altere as propriedades de IKE da criptografia DES para concordar com o DES-56, Algoritmo de Criptografia no Concentrador VPN.
Altere as propriedades de IKE para hash SHA1 para concordar com o algoritmo SHA/HMAC-160 no VPN Concentrator.
Altere estas configurações:
Modo DeselectAggressive.
Marque Suporta sub-redes.
Marque Pre-Shared Secret em Authentication Method (Método de autenticação). Isso está de acordo com o Modo de autenticação de chaves pré-compartilhadas do VPN Concentrator.
Clique em Edit Secrets para definir a chave pré-compartilhada para concordar com a chave pré-compartilhada real do VPN Concentrator.
Na janela Policy Editor, insira uma regra com Source e Destination como "inside_cisco" e "cpinside" (bidirecional). Ajustar Serviço=Qualquer, Ação=Criptografar e Rastreio=Longo.
No cabeçalho Ação, clique no ícone verde Criptografar e selecione Editar propriedades para configurar as políticas de criptografia.
Selecione IKE e, em seguida, clique em Editar.
Na janela IKE Properties, altere essas propriedades para que correspondam às transformações de IPsec do VPN Concentrator.
Em Transform, selecione Encryption + Data Integrity (ESP). O Encryption Algorithm deve ser DES, Data Integrity deve ser SHA1 e o Allowed Peer Gateway deve ser o gateway Cisco externo (denominado "cisco_endpoint"). Click OK.
Depois de configurar o ponto de verificação, selecione Policy > Install no menu Checkpoint para que as alterações tenham efeito.
No momento, não há procedimento de verificação disponível para esta configuração.
Esta seção fornece informações que podem ser usadas para o troubleshooting da sua configuração.
Quando várias redes internas adjacentes são configuradas no domínio de criptografia no ponto de verificação, o dispositivo pode resumi-las automaticamente com relação ao tráfego interessante. Se o VPN Concentrator não estiver configurado para corresponder, o túnel provavelmente falhará. Por exemplo, se as redes internas de 10.0.0.0 /24 e 10.0.1.0 /24 forem configuradas para serem incluídas no túnel, elas podem ser resumidas para 10.0.0.0 /23.
Possíveis depurações do VPN Concentrator incluem IKE, IKEDBG, IKEDECODE, IPSEC, IPSECDBG, IPSECDECODE. É configurado em Configuration > System > Events > Classes.
É possível exibir depurações em Monitoring > Event log > Get Log.
Selecione Monitoring > Sessions para monitorar o tráfego do túnel de LAN para LAN.
Selecione Administration > Administer Sessions > LAN-to-LAN sessions > Actions - Logout para limpar o túnel.
Observação: esta era uma instalação do Microsoft Windows NT. Como o rastreamento foi definido para Long na janela Policy Editor, o tráfego negado deve aparecer em vermelho em Log Viewer. Uma depuração mais detalhada pode ser obtida com:
C:\WINNT\FW1\4.1\fwstop C:\WINNT\FW1\4.1\fw d -d
e em outra janela:
C:\WINNT\FW1\4.1\fwstart
Emita estes comandos para limpar SAs no ponto de verificação:
fw tab -t IKE_SA_table -x fw tab -t ISAKMP_ESP_table -x fw tab -t inbound_SPI -x fw tab -t ISAKMP_AH_table -x
