Hi, ps: sorry for the bad English, I translated this, I'm french. I use the latest version of ISPConfig 2. A domain is functional depui ISPConfig. To do this I create a functioning primary dsn = ns.powaserv.eu I would like to create a second dns, so a secondary. I create from the panel ISPConfig DNS, but this one does not. the secondary dns create the logic is ns1.powaserv.eu But that does not respond when I get a request from above it says the port is closed. Can you help me? Thank you.
