OneXray 作者说明 TUN DNS 与路由 DNS 的区别
yiguodev 表示，普通路由模式下，通常的 DNS 查询由 Xray 内置 DNS 处理，单独修改 TUN DNS 地址不会改变这些请求所用的解析器，需要修改路由配置里的 DNS 地址。他在这条回复中表示，下一版将允许在智能路由和自定义路由中修改本地／直连 DNS 地址。
作者原文@yiguodevThank you for the report.
In normal routing mode, typical DNS lookups are handled by Xray's built-in DNS. Changing the TUN DNS address alone therefore does not change the resolver used for those requests; the relevant setting is the DNS address in the routing configuration.
The next release will allow you to customize the local/direct DNS address in both Smart Routing and Custom Routing. Closing this issue with this improvement scheduled for the next release.
