How connectivity works

Nintex Apps can connect to on-premises connections when the connection is network-accessible from Nintex Apps services.

This is achieved through IP allow-listing, where network firewalls are configured to allow traffic from Nintex Apps service IP addresses. These IP addresses are region-specific and are configured during connection setup. For more information, see Nintex Apps.
