Firewalld rules

Hello, I have and old centos DNS server as a filter, all the traffic to port 53 is captured and redirected to the server, no matter what DNS has the clients configured, migrating now to openSUSE Leap 15.3, the old server has this two rules on iptables:

-A PREROUTING -i ens160 -p udp -m udp --dport 53 -j DNAT --to-destination
-A PREROUTING -i ens160 -p tcp -m tcp --dport 53 -j DNAT --to-destination

but, how can I add these rules on firewalld???

Use direct rules.
