Is there a way to share mouse/keyboard over WAN?

I'm trying to share my mouse and keyboard between my laptop and PC. The issue is both are connected to university WiFi (Glide) and I'm pretty sure LAN security is tight. I've tried various software: Synergy, Barrier, LogiOptions... None work because they're designed to work on a Local Area Network. I was wondering if there was something I can do to have this work over WAN... It's the only plausible solution I'm seeing.

All questions welcome. Any suggestions are greatly appreciated.

Thanks!

You need to use a screen-sharing product that works via the internet.

One computer act as server and the other as client, both establishing their connection via the website of the chosen product.

An example is TeamViewer and its alternatives.
