Hi,

As you know, Ultimate Forms has various capabilities of integrating 3rd party applications in business processes. It could be data import from data bases, SMS integration or Teams channel creation. Although our SharePoint Online customer usually integrate applications that are also on the cloud, in some cases there is a need to integrate business applications located on premises. For example, you might want to import data from an SQL Server DB table into a SharePoint Online list. In most cases, you would need to add an exception to your on-premises firewall to allow our Azure-based services access to your resources.

Until now, we provided a list of outgoing IP addresses that was quite extensive and difficult to work with. Starting next week, we will be using a single IP address for each region. 

Please make sure to visit this page to view the new IP address and add the address in your region that is highlighted in red to your firewall's exclusion list. For now, leave the old ones, you can remove them next Monday when the new IP will be made the only active one.
