# on 主路由 openwrt 已开启 ipv4 ipv6 转发
root@QWRT:~# ip route
default via 221.X.Y.1 dev pppoe-wan proto static
192.168.0.0/24 dev br-lan proto kernel scope link src 192.168.0.1
221.X.Y.1 dev pppoe-wan proto kernel scope link src 221.X.Y.64
```
没有 10.8.0.0/24 的路由,默认网关数据就会从 221.X.Y.1 出去吧,另外 tcpdump 在 wg0 (主路由 openwrt wireguard 接口名)能抓到 icmp request ,但是没有回包。。。
```
root@QWRT:~# tcpdump -i wg0 -nn icmp
