Samba connection

Hi,
I have problem with connection to Hassio via Samba.
I have following confoguration.

{
  "workgroup": "FREDDAGROUP",
  "username": "Fredda",
  "password": "Secret",
  "interface": "",
  "allow_hosts": [
    "10.0.0.0/8",
    "172.16.0.0/12",
    "192.168.0.0/16"
  ],
  "veto_files": [
    "._*",
    ".DS_Store",
    "Thumbs.db",
    "icon?",
    ".Trashes"
  ]
}

And this how the logfile looks like:

But I can not connect to Hassio from my windows machine.
Do I need to specify the “interface”?
How do I know what the interface is?
I’m running Hassio in a Docker on a Ubuntu machine.

Did you try to connect to \x.x.x.x , x.x.x.x being the ip of HA ?

I just discovered that it where the Ufw that where blockning me from connect to the Hassio.
When I disable the Ufw it worked!
What port is Samba using?
I want to open that port in Ufw
