Please tell me does Open-E DSS v6 have any built-in firewall?
During the process of attaching Wireshark gives information about those strange packets

"Destination unreachable (Host administratively prohibited)" type 3 code 10

[To-M]

We do not use any firewall functions in our products. Make sure you are not suing CHAP or the Allow and Deny on the iSCSI Target. If it was working before and then recently for some time check if you can ping the DSS from the Windows system. You might want to submit a support ticket if all else fails so we can investigate the problem.
