What do you mean by “googling my IP address”? When I export an OpenVPN .opvn config, it contains the remote IP address of my real public IP and matches what is shown by whatismyip.com and whatismyipaddress.com.
You can look up the 89.x.x.x IP address on those 2 websites to see who owns it and where it is. Was your router connected as a client to an external VPN when you exported the config?
You can try editing the config file and changing the remote address to your 100.x.x.x Public IP address.
Yes, unfortunately that’s correct - I’m speaking with the ISP to get a public IP.
Assuming that’s done, would the Shadow router allow me to set up VPN server that I’d be able to connect to from outside my home and would allow me to access my home internet? Or, when connecting from outside, I’d only access the internal/home network?
