How to make a network between a router with a static ip and an lte modem?

Question

Computer networks

There is a small workshop with a server and a 1c program on an lte modem, a store with a computer also has an lte modem, and at home there is a router with a static ip. I connect home via rdp, the port is open. You need to go to the server in the workshop with a modem via rdp, from the store from the modem, and from home from static. I do not want to put either the server or the computer on statics at home. There are some options to do it all from home on a router with static tp link archer a6, can you create a network so that the router acts as an intermediate link?

Answer 1

Archer A6 router supports OpenVPN server https ://www.tp-link.com/en/home-networking/wifi-ro...
router. This way you will get ip addresses from the same subnet at all three points in openvpn connections, which will be accessible from all three places.
