Network > DNS Overview

The Network > DNS page allows the administrator to set the SRA appliance hostname, DNS settings and WINS settings.

The hostname section allows the administrator to specify the SRA gateway hostname.

DNS Settings

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.

WINS Settings

The WINS (Windows Internet Name Server) settings section allows the administrator to specify the primary WINS server and secondary WINS server (both optional).

Configuring Hostname Settings

To configure a hostname, perform the following steps:

  1. Navigate to the Network > DNS page.
  2. In the Hostname region, type a hostname for the SRA appliance in the SRA Gateway Hostname field.
  3. Click Accept.

Configuring DNS Settings

The Domain Name Server (DNS) is required to allow your SRA appliance to resolve host names and URL names with a corresponding IP address. This enables your SRA appliance to connect to hosts or sites using a Fully Qualified Domain Name (FQDN).

To configure a DNS server, perform the following steps:

  1. Navigate to the Network > DNS page.
  2. In the DNS Settings region, type the address of the primary DNS server in the Primary DNS Server field.
  3. An optional secondary address can be provided in the Secondary DNS Server (optional) field.
  4. Optionally, use the DNS Search List field to create a pool of domain names:

    5. a. Type the domain suffix in the Domain Search List and click Add. The suffix will be appended with the host name to make a Fully Qualified Domain Name (FQDN), which will be used in host resolution.

    b. To remove a DNS suffix, select the domain suffix from the list and click Remove.

    c. Use the up and down arrow keys to arrange the DNS domain suffixes in the order that will be used to resolve host names.

    For example, your host name is SonicPRS and the usa.n.sonicwall.com and rsc.sonicwall.com DNS suffixes are added to the search list. The first suffix will be appended to SonicPRS to make the FQDN (SonicPRS.usa.n.sonicwall.com), which will be used in name resolution. If the name is not resolved, the next suffix in the search list will be used (SonicPRS.rsc.sonicwall.com).This process continues until the name is resolved or all suffixes have been tried.

  5. Click Accept.
  6. Restart the appliance to ensure new DNS settings take effect.

Configuring WINS Settings

WINS settings are optional. The SRA appliance can act as both a NetBIOS and WINS (Windows Internet Naming Service) client to learn local network host names and corresponding IP addresses.

To configure WINS settings, perform the following tasks:

  1. Navigate to the Network > DNS page.
  2. In the WINS Settings region, type a primary WINS address in the Primary WINS Server (optional) field.
  3. In the WINS settings region, type a secondary WINS address in the Secondary WINS Server (optional) field.
  4. Click Accept.
