O que é a porta 5500?

Port 5500 is used for reverse VNC (Virtual Network Computing) connections, where the remote desktop server initiates the connection to the viewer. This reverse connection mode is used to traverse firewalls and NAT when the viewer cannot directly connect to the server. Standard VNC uses port 5900, while port 5500 is the listener for incoming reverse connections.
