The Network > DNS page allows the administrator to set the SRA appliance hostname, DNS settings and WINS settings.
Figure 21. Network > DNS Page
The hostname section allows the administrator to specify the SRA gateway hostname.
The DNS settings section allows the administrator to specify a Primary DNS Server, Secondary DNS Server (optional) and DNS Domain (optional). The Primary DNS Server is required.
For SRA appliances supporting connections from Apple iPhones, iPads, or other iOS devices using Dell SonicWALL Mobile Connect, the DNS Domain is a required field. This DNS domain is set on the VPN interface of the iPhone/iPad after the device makes a connection to the appliance. When the mobile device user accesses a URL, iOS determines if the domain matches the VPN interface’s domain, and if so, uses the VPN interface’s DNS server to resolve the hostname lookup. Otherwise, the Wi-Fi or 3G DNS server is used, which will not be able to resolve hosts within the company intranet.
