You need access to your home WI-FI network from the outside. I'm behind a NAT provider. How do solutions even exist?

Question

Computer networks

Hello, I have 3 routers: 1. Provider router (GPON optics -192.168.1.50) 2. Keenetic Extra router, which is connected by cable from 1 router of the LAN-WAN type, and it has the entire home network (192.168.0.1) .3 .The Keenetic Start router (192.168.0.39) in the amplifier-repeater mode forms a WI-FI system with router No. 2. The task is to get into the home network from the outside to certain devices. The provider offers to switch router 2 to access point mode and disable DHCP. I would not really like this, since in this case the provider's router will distribute addresses on the home network and I will lose control over them, and this is not an option, since there is a frequent need to limit the speed and time of devices on the local network from the web configurator my Keenetic Extra. The question is - is it possible to organize all this somehow easier,
I read answers to a similar question here, but as I understand it, when connecting LAN-LAN, I will lose control over the management of home network segments. Correctly?

Answer 1

VPN server with white IP. Or buy a white IP from an ISP.

Answer 2

I'm behind a NAT provider. How do solutions even exist?

1. Ask the provider to issue a white IP address - then you will not be behind the provider's NAT, you will only have your own NAT from your router, just forward the ports there and that's it.
   
2. If the first option is not possible, we rent a VDS with a white address, set up a VPN server on it, configure routing on it, and forward ports to our network. The variant is technically more complicated, but quite applicable.
   

Answer 3

I understand that you have a white IP from your ISP? Try switching the gpon router to bridge mode and raise all authorization connections to Extra.

Answer 4

As an option, use a router with open wrt firmware in your home network, which allows you to install a VPN client on the router. If you also run a VPN on a remote PC, then your PC will see everything that is connected to the router.

Answer 5

OSFP is here to help. Well, either as a variant of MPLS + VPLS. And also EOIP.
