How much do you know about networking in general? TCP/UDP/IP/DNS, etc?

I ask because building a simple p2p app is built on top of the foundational stuff.

Probably not enough. I learned from Beej's guide to networking and some excerpts from the Linux programming interface, and have done a bit of network programming in C before moving to Python, but that was decades ago.

Go is great for networking. If you’re interested in tunnels and Ngrok, the original repo is easy to read.

Maybe build a chat app with TCP and UDP. Deploy it on a VM behind a reverse proxy like NGINX. Run the app in Docker or on the VM and setup iptables.

That could be a great summer project. If you want to do low level stuff, Beej is king. You could implement a DNS server. It’s not too terrible.
