Block communication between two bondigs

Hello,

Currently I’ve two bondigs configured in my CCR1016, one for my local network and one for my public network (WIFI). I can’t separate the traffic between both networks

192.168.10.0 → Network LAN
192.168.50.0 → Network External

already create the following rules:

/ip firewall filter
add chain=forward action=drop src-address=192.16810.0/24 dst-address=192.168.50.0/24

but, it doesn’t work

I appreciate and help
