Esta configuração de exemplo criptografa o tráfego da rede atrás da Luz até a rede atrás da Casa (192.168.100.x à rede 192.168.200.x). A sobrecarga da Tradução de Endereço de Rede (NAT) também é realizada. As conexões de Cliente de VPN Criptografadas são permitidas na Luz com caracteres gerais, chaves pré-compartilhada e mode-config. O tráfego à Internet é traduzido, mas não criptografado.
Não existem requisitos específicos para este documento.
As informações neste documento são baseadas nestas versões de software e hardware:
Software Cisco IOS® versão 12.2.7 e 12.2.8T
