How to forward the IP addresses of one router through another (it turned out to be NAT, you need to remove / cancel it / what else to say)?

Question

Computer networks

There are two routers and two users.
The network is like this:

WAN - Wired Router - Wireless Router - Wireless User
                  \
                    Wired User

Wired Router: D-Link DIR-100 (PU - 192.168.0.1)
Wired User (192.168.0.100, 192.168.56.1; PC)
Wireless Router: Netis WF2411R (192.168.0.101; PU - 192.168.1.1)
Wireless User (192.168. 56.2; Smartphone / Printer)
D-Link issues addresses 192.168.0.100 - 192.168.0.255, and Netis 192.168.56.1 - 192.168.56.255, so there should be no conflicts.
The Wireless User can send requests to the IP addresses of the Wired Router and the Wireless Router, but the Wired User cannot send requests to the addresses of the Wireless Router. How to fix it?

Answer 1

If the presence of such a topology is not essential, do the following:
1. Disable the dhcp server in the netis settings.
2. Disconnect the incoming cable from the netis WAN port and plug it into any other free one.
As a result, all devices will be on the same network, and netis will work as a switch.

Answer 2

The Wireless User can send requests to the IP addresses of the Wired Router and the Wireless Router, but the Wired User cannot send requests to the addresses of the Wireless Router. How to fix it?

Register routes.
