Unable to reach the router admin interface.
I'm staying at my in-law's for a holiday event, and the router is in my sister's place. That means I don't have direct access to it right now. I'm not sure what IP address I was using when I connected, since I didn't run ipconfig yesterday... (I'm a little embarrassed about that)
It seems you're suggesting it's not possible without a VPN or similar method.
Access the router only when connected to its local network, you'll need to arrive at your sister's location first.
You're at home with your own router, trying to connect remotely to another router online. The straightforward reply is no—this isn't feasible. Most routers don't expose their web interfaces via the internet due to security measures. To reach private IPs, you'd typically need their public IP address or a VPN connection.
