Connect a remote lan to a separate lan without changing settings on either remote LAN router
I'm trying to figure out how to let my adult kids access my locally hosted game services without opening network ports on my router. I can't change the settings on their routers, because they're locked down by the ISP and getting new routers isn't a realistic option for them
Is an exit node at their homes about to basically intercept a fqdn request from any device on their LAN and tunnel it through the VPN while still allowing them to browse the Internet and their home lan from their own ISP? If I could set up something like a raspberry pi as an exit node, would they just be able to plug it into an whether cable and power it on with no added configuration on their end?
