Network Connectors
Objective
This guide provides instructions on how to create a Network Connector using the guided wizard in F5® Distributed Cloud Console (Console). For more information on a site, see Site.
A Network Connector is used to create a connection between two virtual networks on a given site.
There are three types of network connectors:
-
SNAT, Site Local Inside to Site Local Outside
: A default route is added in the inside network with a Customer Edge (CE) server as a gateway. As the outside network does not have any visibility of the inside network, packets are pushed through Source Network Address Translation (SNAT) 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 L3 virtual routing and forwarding (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 L3 VRF.
You can also enable a forward proxy on the network connector, where the traffic is pulled from the data plane and inserted into the proxy, allowing 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 prerequisite applies:
An F5® Distributed Cloud Services Account. If you do not have an account, see Create an Account.
Configuration
The following video shows the Network Connector object configuration:
Create a Network Connector
Perform the following steps:
Step 1: Start Network Connector object creation.
-
Log into Console.
-
Click
Multi-Cloud Network Connect
.
Figure: Console Homepage
- Select
Manage
>Networking
>Network Connectors
.
Figure: Network Connectors
- Click
Add Network connector
.
Step 2: Configure Network Connector.
- In the
Name
field, enter a name for the Network Connector object.
Figure: Network Connector Configuration
-
Optionally, select a key-value pair from the
Labels
field and add an optional description. -
From the
Select Network Connector Type
drop-down menu, select the network type. There are three options:-
If you select
SNAT, Site Local Inside to Site Local Outside
, theRouting Mode
is set toDefault Gateway
as a default value. TheSNAT Source IP Selection
is set toInterface IP
as a default value. -
If you select
Direct, Site Local Inside to a Global Network
, set theGlobal Virtual Network
type from the options available. -
If you select
Direct, Site Local Outside to a Global Network
, set theGlobal Virtual Network
type from the options available.
-
-
If you select
Direct, Site Local Inside to a Global Network
orDirect, Site Local Outside to a Global Network
, select a virtual network from theGlobal Virtual Network
drop-down menu. Or clickCreate new virtual network
. -
From the
Select Forward Proxy
drop-down menu, select whether to apply a forward proxy:-
If you select
Enable Forward Proxy
, clickShow Advanced Fields
to display more options. -
To configure
Skip Protocol parsing
, clickAdd item
to set an IP prefix to prevent protocol parsing, and clickAdd item
to set a TCP port number to prevent protocol parsing on. -
To configure
Failure handling for upstream connection
, set the number of attempts to connect after a failure occurs on an upstream server. Set theConnection Timeout
in milliseconds. For example, 2000 milliseconds are equal to 2 seconds.
