Description

作者您好，想来讨论一个代理ICMP流量的问题。 当前我打算使用tun2socks生成虚拟网卡接口utun123 ip:198.18.0.1，代理成ss流量到本地8080端口，再用gost监听本地8080端口，搭建隧道和服务端的gost通信。 这样当然要配置本地路由表，让我想代理的目标ip到198.18.0.1，tcp和udp流量都没问题。 但我ping站点的时候发现icmp报文实际上是由虚拟网卡198.18.0.1回复而不是我想访问的服务回复的，延迟非常低，流量没有走出物理网卡接口…… 大概是需要把icmp报文代理成ss的流量？ 看过#39但是感觉太久远了，代码相差巨大，而且涉及gvisor有些没看懂。 请问有没有比较好的办法解决这个问题呢？十分感谢。

ICMP工作在L3层，代理工作在L4，这两个目前在理论上是没法实现转发的。

谢谢！ 请问怎样可以让utun123不响应icmp报文呢？打算直接监听所有icmp流量然后转发出去了。 Thanks！ Is there any idea to make utun123 not response to icmp packets? I'd like to listen all icmp packets and forward them out.

Is is possible to make an extension to socks protocol (or create a new transport) to handle ICMP with a compatible server?

You can try a UDP-based ping tool between a server and your PC to simulate ICMP communication. However, it is limited to ping only. Additionally, if the server does not belong to you, this idea may be impossible.
