Conditional forwarding

Expected Behaviour:

I want to setup conditional forwarding, in the little box below the option I put true,192.168.50.0/24,192.168.50.1
192.168.50.1 Is my router gateway
Its running on a synology nas, with a 4 core cpu and 8 gigs of ram (DS1525+)

version: "3"
services:
  pihole:
    container_name: pihole

    ports:
      - "53:53/tcp"

      - "67:67/udp" # Only required if you are using Pi-hole as your DHCP server
      - "8090:80/tcp"
    networks:
      # Use ph_network (MacVLAN) to give Pi-hole an external-facing IP on your LAN
      ph_network:
        ipv4_address: 192.168.50.198
        # priority: 1000 
      # Use ph_bridge (internal) for fast, secure communication with Unbound

            gateway: 192.168.50.1 

Actual Behaviour:

Its just spamming pi hole with a BUNCH of queries, like 5k q/s of
one of them were:
6.97.163.132.in-addr.arpa

Debug Token:

https://tricorder.pi-hole.net/73EeW8hh/

That's a query for the hostname belonging to the ip 132.163.97.6, which is time-e-wwv.nist.gov, presumably being used as an NTP server by one or more of your devices.

That is not within your specified range 192.168.50.0/24, so would not be sent to your router. It would be sent to your configured upstream the same as any other query.
