When you setup a network, typically you setup a DNS zone for your internal computers. This zone is hosted by your DNS server. Your DNS server needs to know what to do with queries for zones it does not host itself. Typically the DNS server can figure this out on it's own by asking the root servers, but this can be dangerous for your server. Additionally, if you do this you lose some features of SecureSchool.

- To add an entry to the forwarder list, click the "+" button and put in the IP address of the appliance
Once everything is updated, click the "Save" button.
