How It Works:
- Get-NetFirewallProfile returns the status for each of Windows' three firewall profiles - Domain (when connected to a corporate domain network), Private (trusted home/work networks), and Public (untrusted networks like coffee shops).
- Enabled shows whether the firewall is actively turned on for that specific profile - each profile can be enabled/disabled independently.
- DefaultInboundAction/DefaultOutboundAction show what happens to traffic that doesn't match any specific rule - NotConfigured typically falls back to the system default (block inbound, allow outbound), while explicit Block/Allow values override that default.
