VPN：Cisco/Watchguard：IKE 与远程对等端失去联系

我正在尝试在 Cisco ASA 5510（7.0(5) 固件，IP 222.222.222.222）和 Watchguard X750e 防火墙（10.2 固件，IP 111.111.111.111）之间建立局域网到局域网 VPN。

第 1 阶段启动，但日志中出现消息“IKE 与远程对等端失去联系，正在删除连接”，并且 ASa 从未启动第 2 阶段配置。这可能是什么原因造成的？

日志和配置信息如下，抱歉，文本看起来有些难看：

从ASA端的日志来看：

在守望者队结束时：

答案1

以下是有关 IKE SA 不匹配的一些提示的链接，可能会有所帮助（也包含一些需要查看的调试命令）：

答案2

您是否尝试过禁用 DPD？不同供应商之间的 DPD 可能效果一般... 两个设备都设置为使用主模式吗？反复检查设置...

答案3

您必须在第一阶段为网关 IP 提供一个 DNS 名称或 IP 地址。

输入IP地址，然后在其下方的下拉框中选择IP。
