你好，我是 Cisco ASA 5000 系列的新手，有两个接口想要在其间进行路由，一个是数据网络 192.168.69.0/24，另一个是语音 192.168.70.0/24，我已添加了这两个接口，并且在同一子网上可以 ping 通相应的网关，但如果我连接到数据交换机端口，则无法 ping 通语音 VLAN，反之亦然。
我认为这与 NAT 有关，所以我添加了 nat 豁免规则，但仍然没有成功。我缺乏理解，因此希望有人能推荐一些书籍或教程网站/视频来帮助我了解 ASA 政策。
问候，
克里斯
请查看以下我的配置：

答案1
您需要全局命令。使用 nat (iface) 命令，您可以指定哪些流量要发送到 PAT（NAT，但所有 IP 都转换为一个 IP），此 IP 使用匹配 nat ID 的全局（iface）命令配置：示例
nat(inside) 1 0.0.0.0 0.0.0.0
global(voice) 1 interface
对于从内部到语音的流量，来自内部接口的任何源 IP 都将通过 PAT 转换为语音接口 IP。也可以使用全局命令指定 IP 地址
您的语音 VLAN 接口应该具有其他安全级别，因为安全级别 0 用于外部接口，而 100 用于内部接口。配置 nat 和全局后，您可以从较高安全级别的接口访问较低安全级别的接口。如果您想从较低安全级别的接口访问较高安全级别的接口，则需要静态
并且您将需要允许/拒绝流量的访问列表，例如 icmp：
access-list acl-inside permit icmp any any
access-list acl-voice permit icmp any any
access-group acl-inside in int inside
access-group acl-voice in int voice
