Götz,

Unfortunately, no.

The nmbd log verifies that the fileserver's samba service is the local
master browser for WORKGROUP on both eth0 and virbr0.

[2021/01/17 19:02:22.190795, 0]
../../source3/nmbd/nmbd_become_lmb.c:397(become_local_master_stage2)
*****
Samba name server LIONSTORE is now a local master browser for workgroup
WORKGROUP on subnet 192.168.1.20
*****

[2021/01/17 19:02:22.191085, 0]
../../source3/nmbd/nmbd_become_lmb.c:397(become_local_master_stage2)
*****
Samba name server LIONSTORE is now a local master browser for workgroup
WORKGROUP on subnet 192.168.122.1
*****

The samba smbd log simply reports the connection denials:

[2021/01/17 23:07:40.304626, 0]
../../lib/util/access.c:371(allow_access)
Denied connection from 192.168.1.30 (192.168.1.30

There's nothing in the SELinux logs for that date.

I checked firewall-config on the storage server and verified that the
samba service is allowed (but not samba-client or samba-dc).
