Maybe the ports are not opened in your firewall iptables??
Take a look:
Type in the shell “setup”
Select “Firewall configuration”
Select “Customize”.
Also remember that you don’t need to enable IPTables if you got InterWorx, then you have APF as your firewall. And if you want you can install also BFD for Brute Force Detection.
I hope this will help you (Happy new year you all)
