其实Mikrotik的gre的keepalive包，处理的是有些问题的。
如果你安装Mikrotik的机器，之前我测试过7.x版本的都有问题的。
当 wan ip 不是一个真的公网ip（过nat的，都有问题。例如：你的公网ip是4.5.6.7，但是你的服务商给你做的nat，你实际wan ip配置的是192.168.5.15）
Mikrotik的gre的keepalive包的结构中
inner daddr 就是这个内网ip：192.168.5.15。而不是正确的4.5.6.7这个ip。（这个问题，也反馈给Mikrotik过，但是没有修改的意思）

你可以对比下，之前可以的系统和不行系统的一些细节情况，例如:iproute2的版本，libbpf的版本，kernel的版本等。列举出来。
也许可以发现问题之所在。
