Required Action

Prior to November 13, 2023, please ensure that your agents can connect to any Cloud SWG data center to maximize failover opportunities. 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).

  • Firewall rules regulating connectivity to/from your network to Cloud SWG should be adjusted to allow traffic to pass to the IP network listed above.
  • Third party applications that regulate connections by source IP address should be updated to accept connections from the IP network to ensure traffic proxied through Cloud SWG can reach the applications.
  • Auth Connector must be able to communicate with all IP range listed above, on TCP 443, where applicable.
