Adding Exceptions To The Windows Firewall

Windows Firewall operates as a firewall for host-based traffic you assign to an IP address, unlike router-based firewalls that you put at the boundary of a private network and the Internet. For inbound traffic, Windows Firewall is reliable. You must configure firewall exceptions if System Recovery Monitor or System Recovery console is used remotely. You do not need to configure firewall exceptions if System Recovery is configured locally.
