Hi, I’m looking for a detailed procedure of creating a OpenVPN and connect it through my remote RUT240 so that the remote device can have internet access via our office network.
The main reason of doing this is to upgrade the internal modem through RMS as the remote devices doesn’t have any internet on it but we can access those routers from our office network.
I want to create a OpenVPN (Server as my laptop - it’s Public IP)
client will be remote router (RUT240)
I tried the procedure multiple times but VPN doesn’t connect. Therefore, i’m looking for a detailed step by step guide with an example of public ip (17.5.7.3) & the LAN/LTE IP through which we can access Router(RUT240) from our office is for example (192.168.1.36)
How should i configure server along with what parameters? Also how should i configure client on RUT240 along with what settings that really works. Thanks
Hello,
To begin, could you kindly share a simple topology diagram with IP addresses of the intended setup? At the moment, it’s a bit difficult to fully understand how you plan to structure the connections.
Also, could you please clarify, when you mention “updating the internal modem through RMS”, are you referring to updating the device’s RutOS firmware remotely via RMS, or do you mean updating the modem module firmware itself?
From your current description, it sounds like you’re aiming to set up a Layer 2 OpenVPN bridge (TAP mode) between your remote site and office, where your laptop acts as the OpenVPN server with a public IP, and the RUT240 connects as a client.
If that’s the case, there’s a detailed guide on how to configure two same-subnet office networks using OpenVPN TAP mode available here:

And for configuring your Windows/Linux computer as an OpenVPN server, you can follow these instructions:

Looking forward to your clarification.
