Configuring a DNS Server for HTTP Services
You can configure the DNS server (primary and secondary for redundancy) that you want to use for your HTTP services. If you configure a proxy server with an FQDN, this is the DNS server that the device uses for resolving the domain name into an IP address.

To configure DNS servers for HTTP services:
|
|
1.
|
Open the General Settings page (Setup menu > IP Network tab > HTTP Proxy folder > General Settings): |
|
2.
|
In the 'Primary DNS Server IP' field, enter the IP address of your main DNS server.
|
|
3.
|
(Optional) In the 'Secondary DNS Server IP' field, enter the IP address of the secondary DNS server.
|

The DNS servers that are configured for IP Interfaces (see Configuring IP Network Interfaces) are not used for HTTP services. Only the DNS servers configured in this section are used for HTTP services. |

When generating the NGINX configuration file, the device includes the resolver directive, specifying the primary and secondary DNS servers, as configured above. However, NGINX supports optional parameters that allow you to fine-tune the behavior of the DNS resolution. You can include these additional parameters using the ini file parameter [NginxResolverParams), which is added to the resolver directive when the device generates the NGINX configuration file. For more information on these optional parameters, go to http://nginx.org/en/docs/http/ngx_http_core_module.html#resolver. |
