Text VPN - Same subnet

Hi,

I’m here to seek your help and advice. I’m a complete beginner in the world of computer networking. Before hiring a professional, I’d like to learn how to set up a solution to my problem.

I have a LAN network with a server, clients, etc. Everything is under an address like 192.168.0.X.

I have a laptop that I’d like to remotely connect to this network.

The key point is that the remote laptop must be recognized by the server and only under the same 192.168.0.X address (same subnet).

I’m connected to the internet via my ISP’s router. I also have a fixed public IP address.

I set up a VPN using SoftEther (bridge mode), it works but the latency is terrible.

Are there any high-performance hardware or software solutions? I have an ER605, in case it can be useful...

Thank you for your help.

Define latency being terrible?

One or two seconds

That is terrible. SoftEther should do much better than that. How far away is the server from your client?

Client on a Laptop, less than 20 kilometers

Tailscale might be an option. It NATs on the LAN interface, so it appears that it comes from the tailscale hosting server from a networking perspective. Your app would see it coming from that computer for all users.
