client ping client timeout #8

Closed mmmiii33 closed 6 years ago

mmmiii33 commented 7 years ago

A Server 、B Client、C Client

A<<--------->>B ok A<<--------->>C ok B<<--------->>C timeout

B和C之间不能通过A来中转？以后有没有支持的计划？

直接打开Linux的 ip_forward 即可。

之前的测试可能有问题，现在重新测试是通的，但是在B ping C的时候提示“From 10.33.0.1: icmp_seq=2 Redirect Host(New nexthop: 10.33.0.3)”，这个是正常的？

A Server 10.33.0.1 B Client 10.33.0.2 C Client 10.33.0.3

当 ABC 处于同一网段时候， A 会告诉 BC，你俩直接通过链路层就可以通信，你们之间的通信不必先把包交给我。所以提示 “From 10.33.0.1: icmp_seq=2 Redirect Host(New nexthop: 10.33.0.3)”

我猜测你B上路由规则是 ip route add default via A dev mv0 你只需在 B 上加一条 路由规则就行了 ip route add ABC_subnet/prefix via dev mv0

不管了，反正数据能通，不止minivtun这样，shadowvpn也一样的会有这样的提示。
