s3 service using s3cmd tool through URL based firewalls

Question

I am behind a URL based application firewall and currently using s3cmd tool to access amazon's s3 service. Doing a bit of searching has asked me to whitelist s3.amazonaws.com but I see that s3cmd uses a custom URL which goes by s3://[bucket-name].

Would whitelisting amazonaws.com still work in this case or is there something else that would need to be whitelisted?

Answer 1

Does your proxy accept wildcards? You'll want to whitelist *.s3.amazonaws.com at least, and most likely *.s3-*.amazonaws.com if you point at region-specific endpoints.
