Rut241 Scada connection

Hello. I have a RUT241 installed in a remote site. The rut has a sim card with a private and static IP. I access the device remotely via port 443 using the IP from the sim card.

The rut has been configured so the WAN port works as LAN.

There is one device (datalogger) connected to one port of the RUT, and a Scada is connected to the other port.

The datalogger has been configured with the following settings:

IP Address: 192.168.136.11
Gateway: 192.168.136.1
Subnet mask: 255.255.254.0
Additionally, the datalogger has a special setting called additional subnets, which is enabled so that the datalogger can be reached from other subnets. This setting is configured like this: 10.113.14.0/24

The LAN of the RUT has been configured with the following settings:

IP Address: 192.168.136.1
Subnet mask: 255.255.255.0

The Scada works via port 502.

I don’t manage the Scada, but the people who does, say that traffic is getting lost and that the session resets a lot. Is there any setting on the RUT that I need to enable? Thanks

Hello,

I’d like to clarify that for port forwarding to work, your RUT241 must have a public IP address. The issue you’re facing is due to your SIM card using a private IP.

For more details, please refer to our wiki page: Port Forwarding Guide.

Please let me know if you need further assistance.

Best regards,

Hi Marija, I apologize because I made a mistake in the post title. The question is not about port forwarding but about Scada access, I have just changed the post title.

Additionally, I would like to understand why port forwarding needs public IP address. The sim card is inside a VPN and I’m accessing the router via HTTPS from within the same VPN network. I don’t understand why port forwarding wouldn’t work

Hi Marija. Can you please help with the initial question?

Hello,

Could you please provide a topology of your setup, including all devices and their IP addresses (both local and VPN IP addresses)?

Best regards

Dear Marija, is there a way to share the topology privately? Thanks

Hello,
