Amazon web services AWS带VYOS的区域间VPN

我正在尝试在两个AWS地区（俄勒冈州和爱尔兰）之间设置VPN。在俄勒冈州，我使用了AWS VPN服务，在爱尔兰，我使用了市场上的vyos EC2实例。 在俄勒冈州，我启动了一个实例，并为ICMP请求打开了它的安全组（测试为0.0.0.0/0）。我的Vyos实例的安全组也已打开

VPN两边都有，但我有一个奇怪的问题

测试1：

从俄勒冈州EC2 Ping到EC2 Vyos：正在工作

测试2：

从EC2 Vyos Ping到EC2 Oregon：不工作

但如果我在俄勒冈州EC2上启动wireshark，我看到了ICMP请求，问题似乎出现在ICMP回复上：

11.609958 169.254.12.138 -> 10.10.2.45   ICMP 98 Echo (ping) request    id=0x2f3d, seq=1/256, ttl=63
11.929702   10.0.1.177 -> 10.10.2.45   ICMP 71 Time-to-live exceeded  (Time to live exceeded in transit)
12.610213 169.254.12.138 -> 10.10.2.45   ICMP 98 Echo (ping) request   id=0x2f3d, seq=2/512, ttl=63
12.929659   10.0.1.177 -> 10.10.2.45   ICMP 71 Time-to-live exceeded (Time to live exceeded in transit)
13.610111 169.254.12.138 -> 10.10.2.45   ICMP 98 Echo (ping) request  id=0x2f3d, seq=3/768, ttl=63
13.929952   10.0.1.177 -> 10.10.2.45   ICMP 71 Time-to-live exceeded (Time to live exceeded in transit)

IPs Informations:
10.0.1.177: EC2-Vyos
10.10.2.45: EC2-Oregon
169.254.12.138: The IP of my vti1 in the Vyos conf

测试3：

将爱尔兰的另一个EC2实例Ping到俄勒冈州的EC2：不工作

但在EC2 Oregon实例上，我再次看到ICMP请求（10.2.10是我在爱尔兰的EC2实例）：

我不明白问题出在哪里

更新：

问题解决了

---

您可以在此repo上找到整个配置过程（工作过程）

最后，随着Vyos的升级，我的问题得到了解决。（事实证明，这个问题源于VyOS的bug编号和，已在中修复。）

解决方案（在Vyos实例上，而不是在“配置”模式下）：

现在我可以通过VPN连接ping和访问。唯一仍然不起作用的是test2，Vyos实例无法通过VPN ping，但这对我来说并不重要，所有其他实例都可以通过它访问

---

我创建了一个存储库，其过程是设置AWS跨区域VPN:

俄勒冈州的VPN中是否禁用了源/目标检查？否，我已在我的Vyos实例上禁用，而不是在俄勒冈州的EC2实例上禁用。EC2实例意味着俄勒冈州的VPN实例？或者俄勒冈州的其他测试实例？
