[Feature] A suggestion about tun2socks automatically configuring IP

[tyfxgzs]

Description

I have a general understanding of how to use the project. Now I want to ask if I can automatically configure the IP of tun through the configuration file instead of creating the IP first and then starting tun2socks.

Is this feature related to a specific bug?

No response

Do you have a specific solution in mind?

Actually, if you want some auto configuration through config files, you can do something like:

For example, in macOS, create a setup_macos.sh script to set up the route, e.g.:

#!/bin/sh

sudo ifconfig utun123 198.18.0.1 198.18.0.1 up
sudo route add -net 1.0.0.0/8 198.18.0.1
sudo route add -net 2.0.0.0/7 198.18.0.1
sudo route add -net 4.0.0.0/6 198.18.0.1
sudo route add -net 8.0.0.0/5 198.18.0.1
sudo route add -net 16.0.0.0/4 198.18.0.1
sudo route add -net 32.0.0.0/3 198.18.0.1
sudo route add -net 64.0.0.0/2 198.18.0.1
sudo route add -net 128.0.0.0/1 198.18.0.1
sudo route add -net 198.18.0.0/15 198.18.0.1

And then, run:

$ sudo tun2socks-darwin-amd64 -device utun123 -interface en0 --tun-post-up "sh -c './setup_macos.sh'" --proxy socks5://xxx
