I change the mode to Private.
Then I took the following steps: Protection->Firewall-> settings ->Firewall policies → Packet rules → Add new rule
Then I set the value of the “Adress” field the domain name with * the end (i.e: www.MySite.com/*) which became automaticaly to 0.0.0.0-255.255.255.255

It solves the issue and all web server sites are reachable. Hope its ok.
