How to easily forward/redirect all network traffics through local socks port 1080

How to easily forward/redirect all network traffics through local socks port 1080? I did google this before asking question. I found this link and this link and others too. But there is no simple solution.
(The system preferences network proxy setup just don't work for all apps. )
Is that so hard to do it? I think just some iptables rules should do it. (although I don't know what is the equivalent iptables command in macos, maybe pfctl?). Can anyone show me some simple shell scripts which can achieve this? Thank you very much.

Since nobody posts a shell script (or easy way) to solve my question, I posted my current workaround solution:

  1. Install virtualbox
  2. Install openwrt as the guest OS to virtualbox
  3. Configure the openwrt to become a router which has the lan IP of 192.168.56.2. The lan interface is a Host-only adapter. The wan interface is Bridged adapter.
  4. Configure the openwrt router to do the transparent proxy job that I want.
  5. Change both gateway and DNS to 192.168.56.2 in the host.
    • to change the gateway: sudo route change default 192.168.56.2
    • to change the DNS: must use the UI way. System Preferences --> Network --> Adavanced --> DNS

That's all. So far so good.
