We've had a request to consider providing encrypted access to a CIFS filer. From the quick search I've done so far it appears that SMB itself doesn't provide any encryption options so instead we'd need to use IPSec at the filer and workstation ends. I've found NetApp man entries for the commands to manage this.
Before I dig too deep into this, I'm hoping to get a feeling of whether anyone is using this in the real world. If so, how hard is it to set up? Is there a significant performance overhead? Any other gotchas?
Hope to hear from you,
