PorTrend - firewall statistics

This tools serves for visualization of trends in number of packets blocked by Turris routers' firewalls, split by protocols and port numbers. Chart shows information about number of clients, whose firewalls blocked the incoming packet (series Packets), number of unique remote IP addresses (series Sources) and total number of packets (series Packets) targeting the protocol or combination of protocol/port. Not all of the blocked packets are coming from a communication initiated by the remote address - some packets may be for example fragments of TCP communication, that arrived after disconnection of a Wi-Fi client, or UDP packets that arrived after removing a record in the list of firewall's tracked connections. The statistics are updated once a day.
