@lo0pback 有的光猫自带镜像功能

只要电视(盒子)还能自己安装 app

@DJCNMHG
原来 mullvad 和 tor 有合作啊
第一次见用 pf 的服务商😇

用 pf 的不多吧
这家 vpn 会用到 pf 吗

@wsjjacky 这个设置界面 ui 太难受了 还不如 ipad 呢

监管机?

只能说 nb.

波动厉害是因为 isp 限速策略不行吗

@FaiChou 要看各自的设置和 log 了

@lcdtyph
原来是这样啊 解惑了
https://www.v2ex.com/t/590555
不知道这哥们解决了吗

firewall 不是问题 macos 上有 pf

之前测试 google one vbn
它的 utun 会路由所有的 v4 v6
第一次遇到遇到路由 v6 的 即使本机没有 v6 地址
而且会修改 dns 到 8.8.8.8 4.4 和对应的 v6 地址
cat /etc/resolv.conf
里面是这样显示的

系统设置里面的自定义 dns 已经失效了 google 的 dns 最优先了
不知道用什么方法实现的

@MrGba2z 但是软件也可以不遵守规则强制使用某一个
哪个软件这么厉害?
要怎么应对?

@lcdtyph

所有路由给 utun33
小🐱遇到 ip direct 的时候是怎么处理的
比如让 223.5.5.5 直连 走 default en10 出去
从系统原理上和代码上怎么理解
怎么避免产生回环的?

Flags：路由的标志位
U：Up: 路由处于活动状态。
H：Host: 路由目标是单个主机。
G：Gateway: 所有发到目的地的网络传到这一远程系统上， 并由它决定最后发到哪里。
S：Static: 这个路由是手工配置的，不是由系统自动生成的。
C：Clone: 生成一个新的路由， 通过这个路由我们可以连接上这些机子。 这种类型的路由通常用于本地网络。
W：WasCloned: 指明一个路由――它是基于本地区域网络 (克隆) 路由自动配置的。
L：Link: 路由涉及到了以太网硬件。
Netif： 网络接口，如 en0 ，是我的机器默认 wifi 接口，而 lo0 表示本机（“回环设备”），也就是这条规则的包不通过 Lan 来发出

差不多是这样:?

@ranaanna net.inet.ip.forwarding=1 后 ,其它设备设置网关为 macos 也能上网, nat 的意义是为了隐藏内网设备吗

@xxbing 和谐小组大佬?

问问网关
