I am trying to use the Allow Remote Requests in Mikrotik DNS to make my Mikrotik a DNS server for clients connected over a PPPOE interface but it doesn't work when one of the default firewall rules is enabled. defconf: drop all not coming from LAN, If I disable this rule the DNS requests work as I expect them and requests can go through. Why is this default rule causing the DNS requests to fail when enabled?
Is it safe to disable it?
