You may want to forward a domain to your own DNS server or a DNS server other than your upstream server. We use Local Domain and Local DNS to deal with this kind of need. However, you can set only one local DNS server and the max domain number you can add is 8. Recently, we found that there are people in need of forwarding more domains to multiple DNS servers.

As of v4.6.5.4 of NxFilter and NxCloud, we have conditional forwarder feature on 'DNS > Conditional Forwarder'. You can add as many as domains you want there and you can set different DNS servers for the domains you added.

One thing to note is that you have to use a wildcard there as we use a fast lookup method with Conditional Forwarder.

ex) *.mydomain.local, *
