If not, they have much more specific information in their Knowledge Base (KB) if you search for it.

Check your FW setting:

sudo firewall-cmd --get-default-zone

If it returns “public” – this maybe the problem. The workaround is to change the zone or adding a different range. If you want to continue using “public” zone, then do the following:

sudo firewall-cmd --zone=public --add-port=1025-65535/udp --permanent
sudo firewall-cmd --reload
sudo /etc/NX/nxserver --upnpmap
