在macOs Sierra上设置OpenVPN – 客户端无法访问Internet

我正尝试在我的Mac Mini上安装OpenVPN服务器以及TunnelBlick 。 我已经成功地运行了服务器和客户端。 客户端能够连接和ping到服务器,但问题是客户端无法访问互联网。 它不是一个DNS问题,因为客户端甚至不能ping Google公共DNS的IP地址8.8.8.8

我的服务器已启用push "redirect-gateway def1" 。 这个OpenVPN如何build议客户端networkingstream量需要像在Linux下面的命令那样的NAT

iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE

我不知道在macOS Sierra会有什么类似的

这里是我完整的服务器configuration

 ################################################# # Sample OpenVPN 2.0 config file for # # multi-client server. # # # # This file is for the server side # # of a many-clients one-server # # OpenVPN configuration. # # # # OpenVPN also supports # # single-machine single-machine # # configurations (See the Examples page # # on the web site for more info). # # # # This config should work on Windows # # or Linux/BSD systems. Remember on # # Windows to quote pathnames and use # # double backslashes, eg: # # "C:\\Program Files\\OpenVPN\\config\\foo.key" # # # # Comments are preceded with '#' or ';' # ################################################# # Which local IP address should OpenVPN # listen on?

This example will only work # if you are routing, not bridging, ie you are # using "dev tun" and "server" directives. # EXAMPLE: Suppose you want to give # Thelonious a fixed VPN IP address of 10.9.0.1. # First uncomment out these lines: ;client-config-dir ccd ;route 10.9.0.0 255.255.255.252 # Then add this line to ccd/Thelonious: # ifconfig-push 10.9.0.1 10.9.0.2 # Suppose that you want to enable different # firewall access policies for different groups # of clients.

    (不知道,这是答案,但我没有资格写评论呢。)

    push "redirect-gateway def1"指令告诉客户端通过VPN路由所有stream量。 本手册中的iptables调用意味着在OpenVPN 服务器上执行,以帮助路由/ NAT来自用于互联网的客户端的stream量。

    使用traceroute你应该能够validation你的客户端的数据包至less是第一跳到OpenVPN服务器。

    我完全按照这里的规定做了工作

    从博客引用

    步骤1创build/ private / etc / nat-rules

    根据您的configuration更改此IP地址范围

     nat on en1 from 192.168.0.0/16 to any -> (en1) nat on utun0 from 192.168.0.0/16 to any -> (utun0) 

    步骤2创build/usr/local/nat-pf.sh

     #!/bin/sh sysctl -w net.inet.ip.forwarding=1 sysctl -w net.inet.ip.fw.enable=1 #disables pfctl pfctl -d sleep 1 #flushes all pfctl rules pfctl -F all sleep 1 #starts pfctl and loads the rules from the nat-rules file pfctl -f /private/etc/nat-rules -e 

    第3步创build/Library/LaunchDaemons/org.user.natpf.plist

     <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Disabled</key> <false/> <key>KeepAlive</key> <dict> <key>SuccessfulExit</key> <false/> </dict> <key>Label</key> <string>org.user.natpf</string> <key>ProgramArguments</key> <array> <string>/usr/local/nat-pf.sh</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> 

    步骤4清理并启动守护进程

     sudo chown root:wheel /private/etc/nat-rules sudo chown root:wheel /usr/local/nat-pf.sh sudo chmod 755 /usr/local/nat-pf.sh sudo chown root:wheel /Library/LaunchDaemons/org.user.natpf.plist sudo launchctl load /Library/LaunchDaemons/org.user.natpf.plist 

    重新启动您的VPN服务器,完成!
