Route to DNS

Hi all, i am trying to add a route by mangle to a list, there is a sesion OSPF by default, we add a second wan and I want to resolve the ddns of mikrotik by this wan, if I add a defautl route by the IP all works like charming, but if I do one output mangle with his table with fib, after add the default route refered to this routing table it wont work.

ip firewall/mangle/ print
chain=output action=mark-routing new-routing-mark=CLOUD passthrough=no dst-address-list=CLOUD_MIKROTIK log=no

/routing table
add disabled=no fib name=CLOUD

/ip route
add comment=RUTA_ESTATICA_CLOUD_MK disabled=no distance=1 dst-address=0.0.0.0/0 gateway=VLAN_20_WAN routing-table=CLOUD scope=30 suppress-hw-offload=no target-scope=10


Columns: LIST, ADDRESS, CREATION-TIME
