Omada OC200 firewall outgoing rules?

#DNS
Set up an SDN using ER605 router on a OC200 controller.
Trying to create a firewall rule to prevent DNS circumvention by creating the following setup:
Allow TCP/UDP to *public DNS IP* on port 53
Block TCP/UDP all IP's on port 53
Is there a way to do this on this equipment?
Re:Omada OC200 firewall outgoing rules?
I was mistaken, this looks like it should work on the Router's ACL creation...
1. create the DNS_Requests group
2. create a version that is PERMIT to the Safe DNS IP or IPs (create SafeIP_Group)
3. then a second version that is DENY to IPGroup_Any (as shown below)
