I think you're not familiar with nmap and those definitions.
filtered means that inbound traffic is being blocked by a firewall rule. Either on the
destination or
an intermediate device.
closed means there are no firewalls blocking but that no service is running on the port.
I see, probably my mistake, I though it were the Workstation ports the were reported as
filtered.
Example:
f33g is a GNOME spin using the FedoraWorkspace zone.
f33k is a KDE spin using the public zone
[root@meimei ~]# nmap -p 65000 -6 f33g
Starting Nmap 7.80 (
https://nmap.org ) at 2020-10-27 17:28 CST
Nmap scan report for f33g (2001:b030:112f:2::51)
Host is up (0.00041s latency).
rDNS record for 2001:b030:112f:2::51:

[root@meimei ~]# nmap -p 65000 -6 f33k
Starting Nmap 7.80 (

The key to getting good answers is to ask good questions.
