使用kcptun加速来访问内网单个端口,局域网测试没问题,穿透Openwrt时,端口转发或直接把服务设置在路由器上都不行

[BillYao9]

内网的NAS直接开放端口用于外部访问,速度不稳定,百兆的宽带,有时6-7M/s下载,很多时间只有600-700KB/s. 试图使用kcptun加速来提高速度. 但是外网无法访问网页或ssh或其他. NAS上设置kcptun服务端, Openwrt路由器转发UDP端口到NAS.

局域网内 设置kcptun客户端, 直接连接NAS 或者连接外网IP 都可以访问NAS网页. 外部访问时,可以连接,但是无法访问网页,也测试过ssh连接,同样内网可以访问,外网不可以访问. 两种访问方式使用了同样的配置文件.

外部访问时,服务端1分钟后 stream close 并出现 io: read/write on closed pipe

怀疑与Openwrt本身或者端口转发有关. 难道是运营商有限制 测试过直接将kcptun服务设置在openwrt上,同样的问题,外部不能访问. 测试过使用kcptun访问vps内部的网页.没有问题.
