I need a secure remote-access VPN configured so my Windows PCs can reach my home network whenever I’m away. All traffic will be routed through an ASUS router that already sits at the edge of the network, and I would like to use the router’s built-in VPN features if possible. Security and reliability come first. I’m happy to follow your guidance on protocol choice—whether that ends up being OpenVPN, PPTP, L2TP/IPsec, or another option that works cleanly on the ASUS hardware—but the final solution must establish an encrypted tunnel that Windows 10/11 machines can connect to with minimal setup. What I expect from you: • Configure the ASUS router for the chosen VPN protocol and confirm that it is reachable externally. • Provide clear, step-by-step ...

I have a brand-new Windows 11 Server where both Docker Desktop (latest stable release) and LM Studio are freshly installed. Everything launches, yet containers inside Docker cannot reach the internet and LM Studio obviously inherits the same limitation.
