Free NAT software for Windows?

Question

Computer networks

Friends! Tell me, please, how and with what software it would be possible to make an exit to several nodes in the network through one connected via vpn to a specific server?
That is, as I understand it, the node with the vpn client must be NAT and a gateway for a certain static route registered on clients behind this NAT?
What software (preferably free) can do this? Native Internet Connection Sharing will not work, because. then on this node d.b. ip 192.168.0.1 (or is it already possible?), but this is excluded.

Answer 1

You don't need NAT, usually it's all done by VPN settings. For example, in OpenVPN all this is perfectly configured. The only thing you need to ensure is that the network addresses of the server do not overlap with the addresses of the VPN clients.
For example, if your server is on the 192.168.0.0/24 network and the VPN client has the same network, then the client will assume that the server is on its network and will not use VPN to access the server, which will prevent access or will be, but somewhere else.
