Hello Robin,
Thanks a lot for the response! This is my first time posting, I did not get a notification
that it was accepted to be posted and missed your email.
Coming back to your question, the solution was to set up the policies of the buckets as
described
here<https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-presign…ml>.

Hi there,
We noticed after creating a signurl that the bucket resources were
accessible from IPs that were originally restricted from accessing
them (using a bucket policy). Using the s3cmd utility we confirmed
that the Policy is correctly applied and you can access it only for
the allowed IPs.
Is this an expected behavior or do we miss something?
Can you share the bucket
policy?
Also, are you using some reverse proxy in front of RGW, and if so:
are both the proxy & RGW configured for the correct headers to agree on
the actual source IP.
IIRC depending how the policy is written, you have have either of:
- presigned URL || IP-check
- presigned URL && IP-check
