Port forwarding and marutization on TP-LinK how to make it work?

Question

Computer networks

I have 2 video recorders
1 connected via wifi open ports 80 5445 5446
2 via ethernet ports 80 8000
There is a laptop with open port 80 and others.
And so at the laptop everything is easily forwarded!! All ports that I specify are forwarded!
And the registrars have a problem. I do the same as with a laptop, but they are not forwarded.
192.168.20.6 this laptop works fine
192.168.20.12 this wi-fi router redirects
192.168.20.16 via eth directly connected to
192.168.20.12 everything is available
192.168.20.16 everything is available
I hang ports on 10.168.127.168
And only the laptop hangs hang in principle on 10.168.127.168
Now routing looks like this

Таблица маршрутизации
ID	IP-адрес назначения	Маска подсети	Шлюз	Интерфейс
1	192.168.20.0	255.255.255.0	0.0.0.0	LAN & WLAN
2	10.168.0.0	255.252.0.0	0.0.0.0	WAN
3	239.0.0.0	255.0.0.0	0.0.0.0	LAN & WLAN
4	0.0.0.0      	0.0.0.0      	10.168.0.1	WAN

I can’t understand what’s the matter ... Some kind of Shaitan machine

Answer 1

What you don't understand at all.
Is there TP-Link, behind it are two DVRs and a laptop?
Well then, forward for example like this:
8008 -> 80 port 1 of the DVR
8009 -> 80 port 2 of the DVR
8010 -> 80 port of the laptop
Well, further by analogy.

Answer 2

No no no. It is obvious. I don’t have any ports with allocation, they just ping and the port doesn’t give me anything.
The problem is deeper:

But it won't start the shaitan's car
Suddenly the video recorder started working via ethernet.
double trace route scares me
