single nat is for two different subnets

Dears,
I need to allow internet to my two subnet with mikrotik RB750hex,

  1. 192.168.11.0/24
    2.192.168.33.0/24

I have already created two nat rules but the second one is not working…
how can i do this.

Please make an /export hide-sensitive from New Terminal and paste it here to saw us your current configuration

use only one NAT / Masquerade rule, then select outgoing interface (WAN) in rule, then both subnets will be NATted on this rule
