Address, protocol and port of a destination station are filed in the port block list, if blocking of the destination port on the destination station was selected as a filter’s packet action. This table is likewise a sorted semi-dynamic table. Sorting is done according to address, protocol and port. The table contains the following elements:
Element | Element meaning |
---|---|
Address | Address of the station, to which the blocking should apply. |
Protocol | Used protocol (TCP/UDP etc.) The protocol is decimally indicated. |
Port | Port to close at the station. If the respective protocol is not port related, then the entire protocol for this station becomes closed. |
Timeout | Duration of the blocking in minutes. |
Filter rule | Name of the rule, which has produced the entry (determines also the actions to be executed), when a suitable packet is received. |
