之前在这里研究过的用iptables配置跨网段的端口转发

Assume we have the following network environments:

• Device:
  • eth0 (192.168.6.59): for external access
  • enx000ec6a490c5 (192.168.1.2): for ip camera
• IP Camera：192.168.1.10
• PC：192.168.6.2

1. Since CUDA 9.1 doesn't support LLVM 9.0.0, you need to install Command Line Tool 8.3.2 and switch:

$ sudo xcode-select --switch /Library/Developer/CommandLineTools/
$ clang --version
Apple LLVM version 8.1.0 (clang-802.0.42)
Target: x86_64-apple-darwin17.3.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

2. CTL 8.3.2 is supposed for macOS Sierra 10.12, so you also need to create a symbol link for SDK.
