Knarr can connect to many data sources, and for data sources that are available in the cloud over the internet, you may be able to connect to those data sources without having to deal with firewalls. However, some data sources may be behind your company firewall, which may require your IT department to whitelist certain IP addresses for access to those data sources and/or applications.
Knarr uses the following IP addresses that you should include in your request to your IT department to whitelist (if they are willing to do so):
These IP addresses come from Amazon Web Services (aws.amazon.com).
Knarr only reads data from your environment and does not have the ability to write data back, so there should be a minimal risk for your IT department to whitelist these servers.
It is important to note that Knarr supports Muliti-Factor Authentication, which can be enabled to require you to receive a text message when you log into Knarr for additional security.
