How get access to LAN PCs with DO + OpenVPN?
I've fake IP in local network for some IOT, like 192.168.1.11, 192.168.1.15 etc. My LAN connect to Internet via provider with fake IP too, like 10.10.10.15. I've task connecting (REST) to my IOT-device through Internet. For that I want use DO droplet with real IP(for sample 22.214.171.124) and setup OpenVPN on it. For my home LAN I've buy the Mikrotik Router RB951Ui-2HnD which must allow setup the OpenVPN client. So, my LAN with DO Droplet must be VPN.
And now my question is how to do traffic translation from MY SERVER 126.96.36.199 to LOCAL device IOT 192.168.1.11? I understand that my server have only one IP, but I look that may be port forwording! For sample, if I want send request to my IOT device by 80 port, then I can use for that port forwards, like 188.8.131.52:1234 <=> 192.168.1.11:80, and for second IOT device 184.108.40.206:1234 <=> 192.168.1.15:80, and etc.
I found how to set OpenVPN to DO Droplet, I found how adjust OpenVPN client on the router, but can not found how get simple access to my device. Can you help?
