HI all ,
Today after the enabling of SSH in one of our DFL-2500 firewalls we get the message that license will expire after 2 hours. and after 2 hours firewall stopped working.The message on the firewall screen showed that "DEMO License Expired". Firewall not start after reboot even the system lite indicator not blinks.We tried to connect to the firewall with serial port but were also unsuccessful. Please give us your suggestion regarding this problem.
