# Does Salesforce IP session locking impact FinDock?

The short answer is YES. Here's why...

Salesforce security settings include a range of [Session Settings](https://help.salesforce.com/s/articleView?id=sf.admin_sessions.htm&type=5) to help harden org security. One method is to lock authorized connections to a specific IP address. This is enabled with the **Lock sessions to the IP address from which they originated** setting.

Key FinDock functionality may silently fail if you enable IP session locking. Backend errors such as Internal Server Error 500 can also occur.

FinDock uses a service architecture that leverages dynamic IP addressing. PSP notification handling and FinDock Giving Pages, for instance, rely on tokenization across multiple IP addresses. If sessions are locked to a specific IP, incoming notifications get stuck (and don't arrive in Salesforce). Redirecting and similar aspects of Giving Pages will also fail.
