我正在尝试在隔离网络上的 ASA 5512x 和 5505 之间设置站点到站点的 vpn IPsec 隧道。
我在两台设备上运行了 IPsec VPN 向导并使用了相同的配置，但它们似乎从未尝试相互通信。
5512
- 外部接口：172.16.1.1
- 内部接口：10.10.254.254
5505
- 外部接口 172.16.1.2
- 内部接口：192.168.1.1
我目前仅在每个设备的外部接口之间运行一条网线，我能够从每个设备 ping 172.16.1.x IP。
我是不是漏掉了什么？抱歉，虽然很明显，但我之前从未使用过站点到站点设置。
5512 运行的是 ASA 8.6(1)2，而 5505 运行的是 ASA 8.2(5)...我不确定它们是否只是不兼容，我在网上找不到答案。我想尝试升级 5505，但我目前无法访问 Cisco 帐户下载映像，我正在等待有凭证的同事的回复。
以下是两种设备的配置：

在流量尝试使用隧道（通过匹配加密 ACL）之前，ASA 不会尝试建立隧道。
在到达这一点之前，您需要对当前配置进行一些更改。
- 更改内部接口子网。它们现在都在 192.168.1.0/24 上，因此它们永远无法与 VPN 另一端相同编号子网中的节点进行通信。
将加密 ACL 更改为每个 ASA 上的位置，源是内部网络，目标是远程内部网络。
因此，例如如果您将 5505 上的内部网络更改为 192.168.2.0，那么您需要像这样设置 crypto ACL：
5512：
access-list outside_cryptomap extended permit ip 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.05505：
access-list outside_1_cryptomap extended permit ip 192.168.2.0 255.255.255.0 192.168.1.0 255.255.255.0
然后，当流量从一个子网发送到另一个子网时，隧道应该尝试建立 - 因此从 192.168.1.0/24 中的节点尝试 ping 192.168.2.1。或者，您可以使用命令packet-tracer模拟流量 - 从一个子网到另一个子网的模拟数据包也应该使隧道亮起。
