Cannot connect to Macbook Air (M1) from other devices on the network

I have a raspberry pi with multiple services running on it. It also hosts a personal VPN server. If I need to connect to my Raspberry PI or any other devices on the network, I connect to the VPN, and I ping that service's lan IP. It works for all devices on the network except for my mac. I am neither able to ping nor able to connect to any service on my mac from any other device on my network.

My firewall isn't blocking it, and neither is stealth mode or "Block all incoming connections" enabled.
