ftp through second gateway

Hello!

I have following configuration:

/ip address
add address=192.168.1.1/24 broadcast=192.168.1.255 comment=“” disabled=no interface=lan network=192.168.1.0
add address=84.11.51.251/29 broadcast=84.11.51.255 comment=“” disabled=no interface=wan network=84.11.51.248
add address=88.55.102.2/28 broadcast=88.55.102.15 comment=“” disabled=no interface=wan2 network=88.55.102.0

/ip firewall nat
add action=masquerade chain=srcnat comment=“” disabled=no out-interface=wan
add action=masquerade chain=srcnat comment=“” disabled=no out-interface=wan2
add action=dst-nat chain=dstnat comment=“” disabled=no dst-address=88.55.102.2
dst-port=20-21 protocol=tcp to-addresses=192.168.1.250 to-ports=20-21

/ip route
add check-gateway=ping comment=“” disabled=no distance=1 dst-address=0.0.0.0/0 gateway=
84.11.51.249 scope=30 target-scope=10
add comment=“” disabled=no distance=2 dst-address=0.0.0.0/0 gateway=88.55.102.1 scope=
30 target-scope=10

How can I set up ftp trafic to route through wan2 gateway only? Now packets come through wan2 and go back through wan.
