FastTrack accelerates the processing of packets, started working on firmware from 6.29.
Setting example:
/ip firewall filter add chain=forward action=fasttrack-connection connection-state=established,related
/ip firewall filter add chain=forward action=accept connection-state=established,related
The added rules should be before the others.

/ip firewall filter print
We will move our two added to the top (I have them under ID 33 and 34):
/ip firewall filter move 33 destination=1
/ip firewall filter move 34 destination=2
