## Steps

1. Select a Virtual NGFW Engine to review or edit its properties.
2. In the Name field, edit the name for the Virtual NGFW Engine.
3. (Optional) In DNS IP Addresses field, add one or more DNS IP addresses.
   These addresses are the IP addresses of the DNS servers that the Master NGFW Engine with which the Virtual NGFW Engine is associated uses to resolve domain names. Virtual Firewalls need DNS resolution to contact services that are defined using URLs or domain names, and to resolve fully qualified domain names (FQDNs) used in policies. When DNS relay is configured, these DNS servers are used unless domain-specific DNS servers are specified in a DNS Relay Profile element.
   Note: If you have defined NetLink-specific DNS IP addresses, adding DNS IP addresses overrides the NetLink-specific DNS IP addresses.
   - To enter a single IP address manually, click Add and select IP Address. Enter the IP address.
   - To define an IP address using a network element, click Add and select Network Element.
4. Select the appropriate Categories.
5. Click Next.
   The Review Interfaces for Virtual NGFW Engines page opens.
