Network Connectors

Objective

This guide provides instructions on how to create a Network Connector using the guided wizards in VoltConsole. For more information on Volterra site, see Volterra Site.

A Network Connector is used to create connection between two virtual networks on a given site.

There are 3 types of network connector:

  • SNAT, site local inside to site local outside: A default route is added in the inside network with CE as gateway. As the outside network does not have any visibility of the inside network, packets are SNATed to the outside virtual network IP address moving from inside to outside.
  • DIRECT, site local inside to a global network: Using a dynamic routing protocol, routes from the inside network are injected into the global network to allow that inside network to be routed to the global network (like importing and exporting networks into a L3 vrf).
  • DIRECT, site local outside to a global network: Using a dynamic routing protocol, routes from the outside network are injected into the global network to allow that outside network to be routed to the global network (like importing and exporting networks into a L3 vrf).

On the Network Connector you also have the ability to enable forward proxy, where the traffic is trapped from our data plane and inserted into our proxy - this will allow you to create controls such as forward proxy policies.

Using the instructions provided in this guide, you will be able to create a Network Connector.


Prerequisites

The following prerequisites apply:

Volterra Account

Note: If you do not have an account, see Create a Volterra Account.


Configuration

The following video shows the network connector configuration:

Create a Network Connector

Perform the following steps:

Step 1: Log into the VoltConsole and start Network Connector object creation.

Select Manage from the configuration menu in the system namespace. Select Networking -> Network Connector from the options. Click Add network connector.

Step 2: Configure Network Connector.

Enter the network connector configuration parameters as per the following guidelines:

  • Name: Name of the network connector
  • Label: List of label keys/values pairs
  • Network connector type: Network connector type from the below 3 options.

    • SNAT, site local inside to site local outside: A default route is added in the inside network with CE as gateway. As the outside network does not have any visibility of the inside network, packets are SNATed to the outside virtual network IP address moving from inside to outside.
    • DIRECT, site local inside to a global network: Using a dynamic routing protocol, routes from the inside network are injected into the global network to allow that inside network to be routed to the global network (like importing and exporting networks into a L3 vrf).
    • DIRECT, site local outside to a global network: Using a dynamic routing protocol, routes from the outside network are injected into the global network to allow that outside network to be routed to the global network (like importing and exporting networks into a L3 vrf).
  • Forward Proxy (enable/disable): Enable or disable sending the traffic via a Forward Proxy for extra controls.
