Recently, Teltonika RMS launch OpenVPN Hub Beta. But, I find the problem related to the subnet mask and IP Addresses. When you choose IP Address 192.168.1.X something automatically assign subnet mask 255.255.255.252. Can you please fix this OpenVPN Hub Beta subnet mask problem so, I can ping the other devices. When you do ipconfig in command prompt you can see that this problem.
I look forward to hearing from you soon.
