DHCP Server

When DNS Proxy is enabled on an interface, the device needs to push the interface IP as a DNS server address to clients, so the DHCP server must be configured manually, using the interface address as the DNS Server 1 address in the DHCP Server settings on DNS/WINS. The Interface Pre-Populate option in the Dynamic Range Configuration dialog makes this easy to configure; if the selected interface has enabled DNS Proxy, the DNS server IP is added automatically into the DNS/WINS page. For more information about configuring the DHCP server, refer to Configuring DNS Settings.
