How to I create a 2-Way link using OpenVPN on TP-Link
I am wanting to connect 2 households as a single LAN Network using only native hardware and software. Both households do also have access to a Server computer if translation is required. Here is the network setup of both houses
My House:
ISP: Cox
Personal Modem, Personal ArcherAX1800 Wi-Fi 6 Router (Subnet 192.168.5.1)
300Mb/s max Internet Speed
Server Specs: Intel Celeron J1900 4CPU Processor (it's hardwired into the mother board) with Intergrated graphics. 8GB of Ram. Connected Via Ethernet. However it is also being used as a NAS and a Minecraft Server (and possible other servers in the future, one at a time of course)
His House:
ISP: Brightspeed
ISP owns Modem and the CenturyLink Greenhouse C4000XG Router (Subnet 192.168.0.1) that has to be plugged in first, he also has a Personal ArcherBE3600 Dual-Band Wi-Fi 7 Router (Subnet 192.168.1.1) connected to the CenturyLink Router
100Mb/s max Internet Speed
Server Specs: Intel Pentium G202T 2CPU Processor with Intergrated graphics. 8GB of ram. Connected to the TP-Link router Via Ethernet. Isn't being used for anything as of now.
Both PCs are running Windows 10 Home, and I can chrome remote desktop into his Server, and mine is right next to my main PC with it's own moniter, mouse, and keyboard. Both DirectX version is DirectX 12.
I managed to actually get a one way OpenVPN connection to work, but it's only limited to routers. His TP-Link router is acting as the server and mine as the client, and he has a DDNS set up on his router (and it does work, i did a lot of port fowarding, and other stuff to the Centurylink router for it to work) and mine acts as the VPN Client. I am now able to connect to his routers and that is it. meaning i can change router settings without CRDing into his server computer. I have also confirmed that both sides do not have a CGNET.
I have tried doing a PPTP connection and it failed, and my router cannot do any other type of VPN, just PPTP and OpenVPN
How do I make it two way communication so we can access eachother's devices, especially devices connected to the Centurylink router. and are the Server Computers needed as middle men to allow this open communication. I do not want to download external software, this is a learning experience i want to go through.
