What does the firewall in Safepipe do?

The firewall in Safepipe is a packet-filtering firewall. This means that it regulates the flow of data traffic by filtering data packets according to parameters such as source and destination address, port number, and protocol. The heart of the firewall in Safepipe is the rule table, in which all firewall rules configured on Safepipe are listed. The firewall rules instruct the firewall on how to handle the data traffic to and from your LAN, and the firewall lets you configure rules to suit your particular security needs.
Apart from simple regulating mechanisms, such as accepting or denying data traffic that matches a firewall rule, the firewall on Safepipe also offers modifying security features such as masquerading, static NAT, and (from release 2.2) port forwarding. These features provide extra security for your network in that they allow you to hide the structure of your LAN by mapping single IP addresses, networks, and port numbers to other IP addresses, networks, and port numbers.
Additionally, the firewall in Safepipe includes an intrusion detection module which recognizes hacking patterns such as port scanning.
