Windows Routing and Remote access server

Hello Everyone,

Let me start with explaining the environment we have in Azure:

In Azure:

• We have 4-5 servers. (DC, FS, App, and Windows VPN server.)
• I have one server at home (Application licensing)
• All the users are connecting remotely from home.
• All the users connects to the VPN using windows default VPN to connect to the VPN Server located in Azure.
• The server at home connects to the VPN using windows default VPN to connect to the VPN Server located in Azure. Also, Always on VPN configuration is setup

Here is the what the issue is:

• When users connect to the VPN, they are able to ping the servers located in Azure. However, they aren't able to ping the server located at home or other users connected to the VPN.
• The server located at home on VPN, able to ping the servers located in Azure. However, home server is not able to ping or connect to the user's PC on VPN.

All the workstations are on domain. and i want all the devices (at Azure, home, and user's PC) should be able to ping, connect, RDP, file access, and etc to each other once they are connected to the VPN.

How do we achieve this?
