Is it possible this feature (Super DMZ) on user script level?

This is called Twin IP or Super DMZ or Advanced DMZ or IP Passthrough which using the Public IP on the router and 1 client at the same time.
Usually this feature is used to get NAT1 on the console.

I attach the code.
I am not expert at the code, so I'm curious if this feature is available in the Asus router.

If I am understanding this correctly, this is for a situation where the ISP is providing more than one IP address on the WAN interface? If that's the case then I remember Merlin saying that it's not configuration that he's going to support, but I suppose it could be scriptable if someone was willing to put in the effort.

Router and 1 client (bound by mac address) use same public IP.

Router and 1 client (bound by mac address) use same public IP.

So it's the same as a normal DMZ but without the NAT?

Or Full cone Nat which is added on RT-AC86U work like this?

I don't know well, maybe that is right.

"To have a local network device share the WAN IP address, select Share WAN IP. In this mode, which is also known as super-DMZ mode, a single computer bypasses NAT. You can specify the computer's MAC address in the MAC Address field."

Well I don't see any of that code in the Merlin source, so doing it from outside the kernel sounds challenging. I'd guess that the problem would be the connection tracking, or lack thereof (but I'm not a kernel developer ).

Or Full cone Nat ...

Well putting a client in a normal DMZ gives it full cone NAT, so I'm not sure you'd gain much by using this.
