ICS can be configured on a new or pre-existing dial-up connection or LAN connection. The ICS server must have a connection to the ISP for Internet connection, and a network adapter to connect to the local LAN.

What is packet filtering?

May 7th, 2005

Packet filtering is a method that allows or restricts the flow of specific types of packets to provide security. It analyzes the incoming and outgoing packets and lets them pass or stops them at a network interface based on the source and destination addresses, ports, or protocols. Packet filtering provides a way to define precisely which type of IP traffic is allowed to cross the firewall of an intranet. IP packet filtering is important when users from private intranets connect to public networks, such as the Internet.
