Notes

1. If your local network use public IP ranges instead of private ones, make sure to add respecive RETURN rules to iptables to prevent looping issue
2. Set clash as DHCP's only DNS server to allow domain-based filter (shunting) rules work
3. Use lsof -i udp:53 to check if clash's DNS module work fine, otherwise you may have to kill systemd-resolved and any other processes occupying the UDP 53 port
4. The given scripts will NOT hangle the traffic of gateway itself since it is not recommend to do so. If you want to redirect the egress traffic of the gateway, the following material may be useful

# WSL通过Win访问网络，所以WSL的网关指向的是Windows，DNS服务器指向的也是Windows，设置WSL的proxy为win的代理ip+端口即可
# WSL中的DNS server在/etc/resolv.conf中查看，该文件是由/etc/wsl.conf自动生成的。
# 如果关闭了wsl.conf中自动生成resolve.conf并自行修改了resolve.conf，DNS nameserver并不是本机win ip
# 需要开启wsl.conf的自动生成，再运行以下命令
# https://zhuanlan.zhihu.com/p/153124468

# 添加到环境变量设置中，例如~/.zshrc
export hostip=$(cat /etc/resolv.conf |grep -oP '(?<=nameserver\ ).*')
export https_proxy="http://${hostip}:7890"
export http_proxy="http://${hostip}:7890"
