I am using RUT200 devices to create a LAN-to-LAN connection to the Vigor2925 (the main modem). I use these RUT200 devices to monitor the parameters of PLCs installed in different countries.
The issue I am facing is that the RUT200 devices installed in Vietnam (where the Vigor2925 is located) are working perfectly. However, the RUT200 devices in other countries cannot connect to this Vigor device.
Could you please advise me on what to check and how to resolve this issue?
Thanks in advance!
