Absorbaroo downloads Office 365 Whitelists and syncs them to DNS Edge and Meraki SD-WAN.

Customers using SD-WAN for traffic optimization can leverage this workflow to allow safe traffic to Office 365 sites.

The following is a typical use case architecture: Screenshot


Absorbaroo runs on the BlueCat Gateway platform.

Copy the ABSORBAROO directory to bluecat_portal/workflows/

cp -r ABSORBAROO <bluecat_portal>/workflows/

Install git on the BlueCat Gateway, to download 3rd-party libraries

apt-get install git

Install the following 3rd party libraries on BlueCat Gateway

pip install git+

pip install apscheduler

This workflow runs a background scheduler thread on Flask that fetches the latest whitelists from Office 365. To start the scheduler, add the following line to /portal/ in Gateway

import bluecat_portal.workflows.ABSORBAROO.absorbaroo


The ABSORBAROO workflow has three components that need to be configured via setup pages before it can start to work.

  • Setup Whitelist Screenshot

  • Setup SDWAN Sync Screenshot

  • Setup DNS Edge Screenshot

  • Perform a manual Sync (This also happens automatically based on the set interval) Screenshot
