共性问题

可能会不间断出现DNS泄露，使用了中国的DNS
即使 vim /etc/NetworkManager/NetworkManager.conf
在里面找到[main]并在下面添加dns=1.1.1.1
也是无法解决DNS泄露问题的。
实际上你如果使用nmcli connection wg0去查看，会发现其实dns是没有设置的。你可以去nmtui去设置wg0端口的dns。
即使设置ipv4.dns-priority和ipv6.dns-priority的优先级，将他们改为-50
或者将主要端口优先级设置为10，依然无法解决DNS问题。

NetworkManager orders the DNS servers from different connections based on the ipv4.dns-priority and >ipv6.dns-priority parameter in each connection.

If you set no value or you set ipv4.dns-priority and ipv6.dns-priority to 0, NetworkManager uses >the global default value. See Default values of DNS priority parameters.
