I scanned the CentOS 8 by Nmap:
Code: Select all
# nmap -sS -sU -T4 -A -v -PE -PP -PS80,443 -PA3389 -PU40125 -PY -g 53 --script "default or (discovery and safe)" IP
Thank you.

# nmap -sS -sU -T4 -A -v -PE -PP -PS80,443 -PA3389 -PU40125 -PY -g 53 --script "default or (discovery and safe)" IP

That zone (public) does not seem to have any custom icmp-block rules. Is the ens192 even on the "external"?man firewall-cmd wrote:[--permanent] [--zone=zone] --list-all
List everything added for or enabled in zone. If zone is omitted, default zone will be used.
In other words you have at least three networks?difference VLAN
