Hello,
I have question about firewall.
My zentyal use IP is 192.168.2.XX on my intranet.
I want block any external IP and only allow some external IP to connect to ssh or Zentyal Administration.
I hvae to setup firewall and use "Filtering rules from external networks to Zentyal" this function.
But I found any external IP always connect to my Zentyal server.
How to set it?
