WORKGROUP not show my computer 'VM-OpenMandriva'

Hello,

  • _OpenMandriva Lx version:_LX 4.0

  • _Desktop environment (KDE, LXQT…):_KDE, LXQT

I have appropriated

# firewall-cmd --permanent --zone=public --add-source-port=137/udp
# systemctl restart firewalld

for showing WORKGROUP in
dolphin -> Netzwerk -> Feigegebene Ordner (SMB) -> Workgroup -> only the Host computer is notified.

But after
# systemctl stop firewalld
the Host-computer and my Guest ‘VM-OpenMandriva’ are displayed.

What is necessary to configure in firewall to show both computers with active firewall?
Nothing, it’s Ok after Reboot.

$ sudo systemctl status firewalld
