I have 1 Public & 9 Local port how i can configure “Dmitry on firewalling” on my MT

how to configure this cmd?
/ ip firewall filter
add chain=forward in-interface=Local out-interface=Local action=accept comment=“Allow traffic between wired and wireless networks”

I will have to add this cmd for every 9 local ports?

also what to add in place of Local interface in this cmd?

add chain=sanity-check in-interface=Local dst-address-list=illegal-addr dst-address-type=!local action=jump jump-target=drop comment=“Drop illegal destination addresses”
add chain=sanity-check in-interface=Local src-address-list=!local-addr action=jump jump-target=drop comment=“Drop everything that goes from local interface but not from local address”

please help i have read whole forum still not found any ans on this…

Thanks

instead of interface you can create address list with local addresses and use src-address-list and dst-address-list.

What about port bridging?
