环境

设备：mac mini, synology, mac mbp
surge ponte+gateway+dhcp+enhanced_mode 在 mini, ponte 走公网 ip 的模式
synology docker macvlan adguardhome
主路由 x.x.x.1, mini x.x.x.8, synology, x.x.x.66, dhcp netmask 255.255.255.0
adguardhome x.x.x.77

所有设备配置 dns-server = x.x.x.77, 223.5.5.5, 119.29.29.29

问题

在家时，所有设备，mini/ios/mbp , dns-server x.x.x.77 一切正常
mbp 在外，命令行 dig @x.x.x.77 baidu.com 一切正常，但是 surge conf 里配置的 dns-server x.x.x.77 无效

这里的无效指的是，dns 走的全部都是 223.5.5.5 和 119.29.29.29，没有走 x.x.x.77

mbp 在外使用时，终端 dig 结果

结果显示 223.5.5.5 已经 x.x.x.77 都能正常解析 baidu.com
