这变得相当令人沮丧。我正尝试使用 Cisco 客户端 v5 在 pix 501 上设置 VPN。连接建立正常，但我根本看不到 pix 内部接口上的客户端。以下是配置。
注意：VPN 客户端的 IP 地址范围是 192.168.20.x，LAN 客户端的 IP 地址范围是 192.168.10.x。此外，external_ip = ISP 通过 DHCP 分配的 IP。我注意到，一旦 cisco 客户端连接，ipconfig /all 将显示 Cisco 适配器的默认网关被分配为 192.168.20.1。
任何帮助/指导都将不胜感激。谢谢。

答案1
我需要在这里进行一些澄清才能确定，您的意思是 LAN 客户端无法访问还是 LAN vpn 端无法访问？
我们暂时假设您指的是 LAN 客户端，即您在家中通过 vpn 进入办公室工作，并且需要能够访问该家庭网络打印机。
不幸的是，我这里只有一个 ASA 可以使用，您正在寻找的是“拆分隧道”，它允许 VPN 连接，同时允许 LAN 访问，以及通过本地连接而不是 VPN 进行互联网访问。
需要注意的是，如果您需要使用内部 DNS 来解析办公室 LAN 端主机，则拆分隧道通常会将 DNS 与客户端 LAN 端服务器区分开来。
