Deploy SGOS IPv6 Proxy in a WAN Optimization Deployment

Products

• ProxySG Software - SGOS

Issue/Introduction

Scenario

 

The data center and branch offices typically do not have the same IPv6 transitioning strategy or timeline. During the transitional periods, one possible scenario is that both the branches and data centers are still using an IPv4 network, but their Internet uplink has been updated to use IPv6. The branch and data center start to roll out WAN optimization solutions on the IPv6 WAN link.

 

Solution

 

ProxySG’s ADN solution can support all combinations of IPv4/IPv6 scenarios. The three parts that make up the ADN are the branch network, server network, and the ADN tunnel. Any of these three can be using IPv4 or IPv6 independent of one another.  In this example, we will illustrate the case where the branch office and data centers are IPv4, while the ADN tunnel (WAN link) is IPv6.

Resolution

Deployment

 

1. Configure the branch and concentrator ProxySG to have both IPv4 and IPv6 connectivity. See Deploy ProxySG as an IPv6 Transitional Device.

 

2. On the concentrator, configure the ADN manager to be “self."

 

#(config)adn

#(config adn)manager

#(config adn manager)primary-manager self

 

You can also set this in the Management Console or Sky UI.

 

 

3. On the branch, configure the ADN manager with the concentrator’s IPv6 address. This tells the branch to open an ADN tunnel using IPv6.

 

#(config adn manager)primary-manager <ipv6-address>

 

You can also set this in the Management Console or Sky UI.

 

This creates an ADN tunnel using an IPv6 connection.

 

4. Enable ADN:

 

#(config)adn

#(config adn)enable

 

You can also set this in the Management Console or Sky UI.

 

5. Enable the desired services. In this example, we will use HTTP service:

 

#(config)proxy-services

#(config proxy-services)edit “External HTTP”

#(config External HTTP)intercept transparent 80

 

You can also set this in the Management Console or Sky UI.
