Enable the DNS Forwarder

4. Click Apply All Changes

What did I accomplish?

By enabling the DNS Forwarder option, you LAN will operate as follows:

1. IP Phones will use your trixbox Pro as their Primary DNS server.  The phones search for the IP of the server hostname ( sNNNNNN.trixbox.fonality.com )
2. Any PC attached to the LAN port on the back of the phone will send DNS requests to your trixbox Pro .  Your trixbox Pro will then immediately forward these requests to your actual company DNS server.  Because both the trixbox Pro and your computers all exist on the same LAN, this forwarding operation is so fast that you will not notice any lag at all when browsing external domains (the web, an external FTP server, an off-site data center via VPN, etc.)
