TIP: DNS Query Order (sequentially vs. parallel)
Don't know if this has been mentioned before or not. Sorry if it has and I jsut couldn't find it.
By default pfSense DNS Forwarder (dnsmasq) queries each of it's DNS servers all at once (parallel).
If you'd rather each of the DNS servers be tried sequentially one at a time.
Add the dnsmasq 'strict-order' option to Services: DNS Forwarder - Advanced
