RT,

光猫型号，hs8145x6, 电信最新款千兆猫，查了下自带 udp-tunnel.ko 。想着能不能编译下 wireguard 模块。居然好像成功了。

用 lsmod 查看，wireguard 模块加载是成功的。
运行 wg，没有显示协议不支持。

但是，用 ip link add wg0 type wireguard, 显示 segment fault.
dmesg 查看了下日志，没看懂。
暂时不搞了。
还是老老实实地用 ss 吧，毕竟不需要内核模块支持。

具体编译，wireguard-linux-compat

替换掉 Makefile

PWD := $(shell pwd) obj-m += wireguard.o all: make ARCH=arm -C $(KERNEL) M=$(PWD) modules clean: make -C $(KERNEL) M=$(PWD) clean

make ARCH=arm KERNEL=/mnt/linux-4.4.197 CROSS_COMPILE=/mnt/buildroot/output/host/bin/arm-linux-

参考这里的编译方法。 github.com/0neday/OptiXstarHS8145X6/tree/main/persist-root-shell

编译报 undefined，可能与内核的 config 有关，现在找不到适配的 config

能在光猫 x6上 ping 172.217.0.1，在电脑上无法ping。很奇怪，难道要做什么iptables 策略吗？
