Exemplo de configuração de ASA VPN com encenações de sobreposição
Índice
Introdução
Este documento descreve as etapas usadas para traduzir o tráfego VPN que viaja sobre um túnel de IPsec do LAN para LAN (L2L) entre duas ferramentas de segurança adaptáveis (ASA) em encenações e igualmente na tradução de endereço de porta (PAT) de sobreposição o tráfego do Internet.
Pré-requisitos
Requisitos
Certifique-se de você ter configurado a ferramenta de segurança adaptável de Cisco com endereços IP de Um ou Mais Servidores Cisco ICM NT nas relações, e tenha-se a conectividade básica antes que você continue com este exemplo de configuração.
Componentes Utilizados
As informações aqui são baseadas nesta versão de software:
-
Versão de software adaptável 8.3 da ferramenta de segurança de Cisco e mais atrasado.
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.
Informações de Apoio
Cada dispositivo tem um privado, rede protegida atrás dele. Em encenações de sobreposição, uma comunicação através do VPN nunca acontece porque os pacotes nunca saem da sub-rede local desde que o tráfego é enviado a um endereço IP de Um ou Mais Servidores Cisco ICM NT da mesma sub-rede. Isto pode ser realizado com o Network Address Translation (NAT) como explicado nas seguintes seções.
Tradução em ambos os pontos finais de VPN
Quando as redes protegidas VPN sobrepõem e a configuração pode ser alterada em ambos os valores-limite; O NAT pode ser usado para traduzir a rede local a uma sub-rede diferente ao ir ao telecontrole traduziu a sub-rede.
