Nuage Networks SD-WAN Solution Guide
Where Can I Use This? | What Do I Need? |
---|---|

Nuage Networks Virtualized Network Services (VNS) is an SD-WAN 2.0 solution that
automates the provisioning, configuration, and management of WAN connections to provide
the optimal application performance at the lowest cost, while meeting strict business
policy and security requirements for each application. Nuage Networks VNS can provide
this policy-based automation while seamlessly connecting WAN branch sites to on-premises
data centers and private clouds, public clouds, and provider-managed VPN networks. VNS
relies on a central policy repository to define business and application specific rules
that dynamically optimize WAN links and remote branch appliances or devices.
To secure your organization’s access to resources outside the SD-WAN and to the internet,
you can deploy a Nuage Networks SD-WAN with Prisma Access, a cloud-based security
infrastructure that uses next-generation security features. Using a shared ownership
model, Palo Alto Networks manages the Prisma Access infrastructure, while you manage the
process of connecting the Nuage Networks SD-WAN to Prisma Access.
Supported Software Versions and Requirements
Nuage Networks have three types of NSGs:
-
NSG-C Series
-
NSG-E Series
-
NSG-X Series
All of the listed NSGs work with Prisma Access. The only differences are the
resources that they have and the access and WAN interfaces that they support. For
more information, refer to the NSG series product information at http://www.nuagenetworks.net/resources/product-information/. The NSG
series consists of NSG-C (small), NSG-E (medium), and NSG-X (large).
Supported IKE and IPSec Cryptographic Profiles
You onboard your SD-WAN edge devices using a remote network connection between the
edge device at the branch site, HQ, or hub to Prisma Access. Use Prisma Access to
create a remote network connection and create IKE and IPSec Crypto profiles; then,
set up an IPSec tunnel between the SD-WAN edge device and Prisma Access.
The following table documents the IKE/IPSec crypto settings that are supported with
Prisma Access and the Nuage Networks SD-WAN. In addition, the supported architecture
types are listed at the end of the table. A check mark indicates that the profile or
architecture type is supported; a dash (—) indicates that it's not supported.
Default and Recommended settings are noted in the table.
