IP Firewall OS Design Development (Windows Embedded CE 6.0)

1/6/2010

The IP firewall is typically used on an Internet gateway device. It can also be used as a host firewall. The firewall helps protect the device on which it runs and helps to protect devices on the private side of the gateway. The firewall blocks IP traffic at the IP and transport layers.

This firewall uses rules to determine whether to block, allow, or log inbound or outbound traffic. Inbound traffic originates from a host on the public side of the firewall. Outbound traffic originates from either a host on the private side or the device that is running the firewall. For more information about the IP Firewall, see IP Firewall Application Development.
