Good morning  
I have a problem:

_Version ignition 8.1.14_  
_Windows 10 Pro 21H1_  
_Docker desktop version version 4.5.0 (74594)_

I’m doing a redundancy test with 2 docker instances as an attached schema.

 ![2022-02-17 10_07_32-RidondanzaDemo.drawio - diagrams.net](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/b/fb4bf539cfaa1842e9bd5623d3679e7ce8eddbcc.png)

Redundancy is correctly connected between the 2 servers within the docker network via ip 172.19.0.x

The client is on the host machine and connects to the master gateway via exposed port 9088 on ip 10.5.90.253.  
I connect correctly from the browser both to the master gateway on port 9088 and to backup on port 9188.

In the client launcher configuration I insert the master IP, but the address of the “gateway.redundancy” within the configuration automatically takes the IP configured as a backup on the redundancy settings (ie 172.16.0.3).

 ![2022-02-17 10_06_46-Window](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/7/f77543f60fe55f0d5d072d9eae63f2a528f98138.png)

Going to modify the parameter in C: \ Users \ User \ .ignition \ clientlauncher-datavision-client-launcher.json by inserting the correct backup address [http://localhost:9188](http://localhost:9188) instead of 172.19.0.3:8088 (that is internal docker) , and starting the project, the client always points to 172.19.0.3.

The question is:

Is it possible to make the client point to a different backup gateway than the one set up in the redundant gateway?

Thanks

You can set a Public HTTP address that will be delivered to clients and designers for both servers:

Hi, thanks for reply.

I need to setting in both master and server gateway

master  
public address :localhost  
public port : 9088

backup  
public address :localhost  
public port : 9188

?

Correct?
