How can I access IP addresses on the ISP's network and not my local one?

Question

Computer networks

I'm not a newbie, but there's something I can't figure out.

There is a network:
1) Internet provider (switch)
2) then two wifi-points (bridge mode), IP 192.168.1.xxx is assigned to each
3) well, at the end there is a router with a registered static IP 79.120.53.xxx, mask 255.255. 255.252 and gateway 79.120.53.xxx. In this case, the router issues DHCP addresses to all devices 192.168.1.xxx

Task: to gain access to access points with IP addresses 192.168.1.xxx.

The provider issued a static IP and DHCP is turned off for me, as I understand it. At the same time, access points by mac-addresses are visible in "their" (provider's) network, but not visible in mine.

As soon as I register IP 192.168.1.xxx on the computer and connect the wire directly, both points immediately become visible, but then there is no Internet connection.

If I understand correctly, the reason is that the points are in a different network, i.e. theoretically, if they manually register the provider's IP (79.120.53.xxx), then they should be visible, BUT .. what if these IPs have already been issued to someone else, will there be a conflict?

Are there any other ways to "friend" networks and see access points?

Thank you in advance!

Answer 1

The point addresses will have to be changed to another subnet, the WAN router interface will have to be assigned an additional address from the same subnet.
