Connections Traffic

IPCop uses the Linux Netfilter or IPTables firewall facility to maintain a stateful firewall. Stateful firewalls keep track of connections to and from all GREEN, BLUE and ORANGE network IP addresses, based on both the source and destination IP addresses and ports, as well as the state of the connection itself. After a connection is established involving protected machines, only packets consistent with the current state of the connection are allowed through the IPCop firewall.

The IPTables Connection Tracking window shows the IPTables connections. Connection end points are color-coded based on their network location. The color-coding legend is displayed at the foot of the page. Information on individual connections is displayed next. Each connection from or to your networks is shown.

Choose between Traffic and Status displays, and click the Save button for IPCop to remember your preferred option.
