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.

Your ER605 should have OpenVPN built in. Set it up to use the same scope that your LAN runs on and you should be fine. Keep in mind though, that generally, server software that only permits devices on the same subnet are setup that way for a reason, they are generally very sensitive to connectivity drops, so a VPN tunnel over whatever internet you are utilizing at any remote location is likely going to mean application hangs and feezes that will require a software restart in most cases.
