求问下Wireguard内置的watchdog要怎么设置自动重拔端口了

ogm

因公网IP变动时不时就要重拔端口才能连接上，看到WG文件下有带watchdog，求问下有大神知道怎么设置吗

添加一个执行/usr/bin/wireguard_watchdog的定时任务即可
例如每5分钟检测一次，即：
echo '5 * * * * /usr/bin/wireguard_watchdog' >> /etc/crontabs/root
也可以在网页上设置：

感谢大神，只需设置定时任务就行是吧，
/usr/bin/wireguard_watchdog的文件不用动了吧

这个不用动，但是你的wg配置文件中的persistent_keepalive要设置

大佬,是按默认设置25秒就好了吗

wireguard_watchdog的建议是25秒
但你也可以按自己需要设置，它会自动识别
