Enabling ufw in the virtual Ubuntu and allowing SSH

antero@VirtualBox:~$ sudo ufw enable
Firewall is active and enabled on system startup
antero@VirtualBox:~$ sudo ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing)
New profiles: skip
antero@VirtualBox:~$ sudo ufw allow ssh
Rule added
Rule added (v6)
antero@VirtualBox:~$ sudo ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing)
New profiles: skip

To                         Action      From
--                         ------      ----
22                         ALLOW IN    Anywhere
22                         ALLOW IN    Anywhere (v6)

antero@VirtualBox:~$

Trying to reach Ubuntu.com:
