Required Action

Prior to the maintenance, for the WSS Agent access method:

• Update any firewall rules regulating connectivity with Cloud SWG to allow traffic to pass to/from the IP networks listed above.
• Third party applications that regulate connections by source IP address should be updated to accept connections from the IP networks listed above to ensure traffic proxied through Cloud SWG can reach the applications.

Failure to make these changes could prevent users from connecting to Cloud SWG, accessing third party web applications, or authenticating against the service using the Auth Connector (where applicable).
