• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Resolved Plesk Firewall and Samba

After a small private chat, we found IPv6 Neighbor Discovery firewall rule was set to block. This rule will prevent the server from finding routers to reach the internet.

Once we changed it to allow, the SMB server was reachable via IPv6.
Thank you for sharing the solution.

Out of curiosity, was the Neighbor Discovery rule as custom added rule added the Plesk firewall?
 
Hi Kaspar,

The rule is part of the normal Plesk Firewall rules. It's defaulted to allow but it was changed to block in this case.
