Answer 3

I will offer a slightly hardcore solution. Install Wireguard on each computer, forward ports to the wireguard of each computer on the router. Unlike conventional VPNs, wireguard can connect one network to several points and is a p2p protocol (whoever knows the "white" address is the client and no dhcp). But although it is relatively simple, you will have to learn how to work with it.
As a result, it will be possible to rummage through the directories of computers using the built-in tools of Windows, almost like in a local area. Connect via RDP, etc. And you don’t have to do anything with a crooked router, because for him it’s just UDP.
The downside is that broadcast traffic does not go through and you will not be able to see the computers through the Windows computer browser. And more gestures than if the router could be a vpn router. Example config on your computer

[Interface]
PrivateKey = IPqn1...секрет-0...acmc=
ListenPort = 4049
Address = 10.17.4.1/24

[Peer]
PublicKey = публичный ключ первого компа
AllowedIPs = 10.17.4.0/24 # правило брандмауэра, обязательно
Endpoint = myhost.ddns.example.net:4050 #public ip

[Peer]
PublicKey = публичный ключ второго компа
AllowedIPs = 10.17.4.0/24 # правило брандмауэра, обязательно
Endpoint = myhost.ddns.example.net:4051 #public ip

An example of a config of one of the computers

[Interface]
PrivateKey = IPqn1...секрет-1...acmc=
ListenPort = 4050
Address = 10.17.4.2/24

[Peer]
PublicKey = публичный ключ вашего компа
AllowedIPs = 10.17.4.0/24 # правило брандмауэра, обязательно
#Endpoint = необязателен

Answer 4

VPN client on the router, static IP addresses on computers, different IP subnets in "your" network and in the parent one. You buy a white static IP from your operator and raise a VPN server. Remote desktop on computers.
