Dropping the firewall made it. Now the NFS server works.

Thanks a lot, Carlos!

Ok, but it is not solved really, just diagnosed. We have to find the correct configuration on the firewall to just open the nfs ports and not drop the entire thing.

First is knowing whether you are using the old SuSEfrewall2, or the new firewalld.

systemctl status SuSEfirewall2

[no response]

systemctl status firewalld

For my purposes, a protection against exterior attacks would be sufficient. But so far, I did not manage to set up firewalld correctly.  Having looked for "ssh" and "nfs" in all zones, I'm not sure if there is some hidden occurrence left. Thank you in advance, Wolfgang
