Firewall / Whitelisting

To be able to reach the S3 service at ds12s3.swissscom.com from your VMs, make sure to whitelist the following IP ranges in your firewall by creating Firewall Rules via the Security page:

• 138.187.65.128/27 (Port 443)
• 138.187.65.160/27 (Port 443)

This is an information message

Important

Make sure to whitelist the entire ranges above and not just single IPs, because the DNS record of the access point can vary in that ranges.
