Network Discovery does not work on Opensuse Server on windows 10

I have a fully operational Windows network with a Opensuse 15.4 server. I can map drives so long as I know the path. What I don’t have is network discovery for the server, although all Windows machines appear in File Explorer. I’ve done a ton of research so I know a few tidbits:

  • NetBeui & SMBv1 has been discontinued from Windows 10 has been replaced by a new DNS method.

  • WSDDS2 must be installed on the OpenSuse server along with firewall port openings and a number of changes to samba.conf.

I am using the following article as a guide: Samba 4, shares, wsdd and Windows 10 – how to list Linux Samba servers in the Win 10 Explorer | Linux-Blog – Dr. Mönchmeyer / anracon . In it is the following requirement to configure the firewall: **Port 3702 (UDP) for incoming packets to the server and outgoing packets from the server to the Multicast address 239.255.255.250

This is the crux of my immediate problem: How is Multicast configured? What utility, and please provide an example.

Network Discovery is not a required function, but I am driven to solve this issue. If you have any guidance in this area, I will be thankful for your tips and advice.

@geno11x11 aside from needing to upgrade your system, as long as the wssd service has been started it will broadcast to that address. You can see with the likes of wireshark and add a filter ip.dst == 239.255.255.250 start the service and you will see activity from the server ip address…

I found that if port 3702 UDP and TCP is added to firewalld, that is sufficient to allow discovery from a Windows host.
