Ok, so I have set up a node via an old PC.

I have Bitcoin Core installed and Electrum Rust Server. Everything is synced and I can connect to it within my home network. I have also installed VPN and TOR and its running well. When I check for peers it shows more than 10.

The main reason for setting this up was for privacy reasons (and of course to help the network).

But I wanted to know now how this helps with my privacy.

Let's say I get some non-KYC coins. How do I use my own node for privacy if I'm outside of my home network? Do I accept it on a mobile wallet like Blue Wallet, then transfer it to my desktop wallet?
I'm not sure how to go about this?

Is it possible to connect to my node when I am outside of my home network?
If anyone can point me to some resources that would be great.
