I'm new to the VPN stuff and have a problem with my first setup.
I created a private VPN with ZeroTier for playing old LAN games with my friends. The problem is that the VPN has an IP address range somewhere at 10.147.0.0 to 10.147.255.255, and old software does not recognize it as virtual LAN. So no servers are listed and a connect command or console sometimes doesn't exist.
The goal is to create an internal route in Windows to link an IP of the VPN to my local net.
I need something like 192.168.0.100 --> 10.147.20.62, to let the old software see the local address, and Windows routes it to the VPN. Is this possible?
I tried
route add 10.147.20.62 mask 255.255.255.255 192.168.0.100 IF 24
and the other way round
route add 192.168.0.100 mask 255.255.255.255 10.147.20.62 IF 24
but a ping 192.168.0.100 tells me the host is not reachable.
Update
As requested, I describe what I actually want the computers to do.
My desktop PC has got an IP address 192.168.0.2, assigned by my local router to my physical adapter. The desktop PC also got another IP address 10.147.x.10 assigned by the VPN provider to my virtual adapter.
The same goes for my friend in another city (VPN address 10.147.x.20).
We can see our shares due to the fact, that we are in the same VPN (10.147.x.0). But because the IP address range 10.147.x.0-255 is not a classical LAN range, some software does not recognize that there is a connection.
I want the virtual adapters address of my friend (10.147.x.20) be accessible by a local IP address 192.168.0.100 in my own network.
I don't know how to call it. Forwarding, masking, routing? But is it possible, what I want my PC to do?
