After adding the "FastTrack" rule special dummy rule appeared at the top of the list. This is not an actual rule, it is for visual information showing that some of the traffic is traveling FastPath and will not reach other firewall rules.

FastTrack can process packets only in the main routing table so it is the system administrator duty to not FastTrack connections that are going through non-main routing table (thus connections that are processed with mangle action=mark-routing rules). Otherwise packets might be misrouted though the main routing table. |
These rules appear as soon as there is at least one fast-tracked connection tracking entry and will disappear after the last fast-tracked connection times out in the connection table.
