Route FTP and cPanel (21 and 2082, 2086, 2087) traffic while balancing multiple WAN

Hi, I have a configuration balancing between 5 WAN lines and 7 LAN, trying to connect via FTP (port 21) traffic is rejected when changing IP I guess, created a packet marking and route for these packages to get a WAN alone but equally does not work. an alternative?

/ip firewall mangle
action=mark-connection new-connection-mark=“trafico_limpio” passthrough=yes chain=prerouting dst-port=21,22,2082,2083,2086,2087 in-interface=bridge_lan
/ip route
geteway=ether4 routing-mark=Trafico_limpio
