As part of Iress’ ongoing work to improve information security and stability, we are updating the network connection for NetIress users.

If you connect to Iress Pro via NetIress and haven’t already done so, please update your network configuration on Iress Pro to use the WebSockets Connection Type on Port 443.

If you have any questions on these changes, there are a number of FAQs below, or you can contact us on with the subject line: Connect Port 443.

The Network Configuration should be set to:

  • Connection Type: WEBSOCKETS
  • Socket Address: PRO.IRESS.COM.AU
  • Port: 443

This is accessed from the Iress Pro menu: Options → Settings. Please select the Network Configuration tabpage. Please ensure that you make this network configuration change on each PC or laptop that you use to login to Iress Pro via NetIress.

Frequently asked questions

How do I tell if I have a NetIress connection?

NetIress users use an internet connection to Iress. This would likely have been configured when you first installed Iress Pro.

What should we do if unable to connect on the new port 443?

We expect that you will be able to successfully connect to this port as this is a standard port number. In case of any difficulties please contact your technology support function who can check your network configuration.

When do I need to make this change?

The new WebSockets connection is already up and running and being used by the majority of NetIress users. Equipment supporting the old existing Sockets connection type is nearing its end of life, and will be decommissioned in January. To benefit from the additional security and bandwidth features of the WebSockets connection, we strongly recommend to update to the new configuration as early as possible.

Will I need to upgrade Iress Pro in order to use the WebSockets connection type?

Our current minimum supported version of Iress Pro is 19.2 though for maximum conformance, we recommend that users run Iress Pro 20.1.11 or above. Our latest version of Iress Pro is available to download here.

Please note that if upgrading your Iress Pro frontend from a version below 17.3, you may need to whitelist the following URL addresses:

  • *
  • *

If these pages are not accessible, you should contact your internal technology team to ensure that the url’s are whitelisted.

Will WebSockets work with my current Operating System (OS)?

Websockets requires that your OS supports TLS 1.2 (note that Windows 7 disables TLS 1.2 by default). Windows 8.1 is the minimum Iress supported version (TLS 1.2 enabled by default from Windows 8.1)

Is it possible to make the WebSocket settings change via a config file rather than in the user settings?

Yes, the change can be configured by deploying registry changes, using the following steps:

  • Within registry, open up Computer\HKEY_CURRENT_USER\Software\DFS\IRESS\dfscom
  • Delete everything in this key
  • Open Iress Pro and configure the Primary and Secondary network settings as required
  • Export Computer\HKEY_CURRENT_USER\Software\DFS\IRESS\dfscom to a registry file

This registry file can then be deployed to users as required according to your internal policies, or provided to users to apply manually if they have admin permissions to their PC.

Can the change be pushed out to users from the Iress Admin > User Manager command?

Yes, Iress Admin users with access to the User Manager command can make the change for their online users. Please follow the instructions below:

1. From the Iress Commands menu, select Admin > User Manager
