I’m on nobara linux (which is a Fedora based distro) and I don’t have ufw (as far as I know it’s ubuntu’s firewall), I tried running:
sudo firewall-cmd --add-rich-rule='rule family="ipv4" source address="192.168.1.1" port port="1900" protocol="udp" accept' --permanent
but this didn’t help at all as i still can’t see the external IP after running “sudo /etc/NX/nxserver --upnpmap
“
