What is a difference between inbound and outbound Azure Firewall rules?

Answer

An inbound firewall rule protects your network from threats that originate from outside your network (traffic sourced from the Internet) and attempts to infiltrate your network inwardly.

An outbound firewall rule protects against nefarious traffic that originates internally (traffic sourced from a private IP address within Azure) and travels outwardly. This is usually traffic from within Azure resources being redirected via the Firewall before reaching a destination.
