• I changed the appliance IP, making it static IP , but I can't connect using http.
  
  Please check if the appliance IP conflicts with an existing one (shutdown the appliance and try to ping). Also check default gateway. If IP and default gateway are right try to connect to http and look at the system log on /var/log/message to find an error message.
