                Clash as transparent proxy gateway via TPROXY
              
          
    Notes

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
Set clash as DHCP's only DNS server to allow domain-based filter (shunting) rules work
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
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
