DNS

Configure the DNS server settings and define the domain name. You can define up to three DNS servers which apply to all Internet connections or use the DNS configuration from the active Internet connection (Primary).

We recommend that you configure up to three DNS servers, if they are located in the headquarters office. All DNS requests from this branch office go to these DNS servers.

By default, the gateway functions as the DNS proxy and provides DNS resolving services to internal hosts behind it (network objects). This option is global and applies to all internal networks.

The Domain Name is automatically appended to:

  • Local hosts (the gateways and network objects) are appended with the domain name when the DNS resolves.

  • The domain name is automatically appended to DNS queries that do not contain one.

By default, the DNS settings are unlocked from plans for new gateways.

This feature is only supported on R77.20 and higher gateways.

To configure the DNS settings of a plan:

  1. Go to Home > Plans.

  2. Click the plan name.

    The Edit page opens.

  3. Click Device Settings > DNS.

  4. Select Manage in SMP.

  5. To configure the DNS servers, click Configure DNS servers and enter the IP addresses for the DNS servers.

  6. To use the Internet connection DNS settings, click Use DNS servers configured for the active Internet connection(s).

  7. To configure the gateways to provide DNS resolving services to internal hosts, click Enable DNS Proxy.

  8. To use the DNS Proxy gateways to treat the local network objects as a hosts list, click Resolve Network Objects.

  9. Enter the Domain Name appended to DNS queries.

  10. Click Save.

To override the DNS settings set by a plan in a gateway:

  1. Go to Home > Gateways.

  2. Click the gateway name.

    The Edit page opens.

  3. Click Device Settings > DNS.

  4. If the DNS settings are locked, click Unlock from plan.

  5. To stop remote management of the DNS settings, clear Manage in SMP.

  6. Configure the DNS settings (see above).

    A browser page opens and shows the progress of the SMP connection to the gateway. The appliance opens on the DNS page. You can now update the local appliance.
