The firewall has a default IP address of 192.168.1.1 and a username/password of admin/admin. We will change these access settings later for security reasons. Install your firewall device and connect power to it. Connect your computer to the MGT port on the firewall through an RJ-45 Ethernet cable.
Go to https://192.168.1.1 from your browser. Log in to the firewall with username and password (admin/admin). Click on 'Device' and then on 'Administrators'. Select the admin role and enter the current password and the new password. Click on 'ok', and your login password for the admin will be changed.
To configure the MGT interface, go to Device > Setup > Interfaces and edit the Management interface. Set the 'IP Type' to static and enter the IP Address, Netmask, and Default Gateway details. Set the 'speed' to auto-negative and select the management services that you want to allow on the interface. Click on 'ok'.
The next step is to configure the DNS, go to Device > Setup > Services. In the services tab for DNS, enter the Primary DNS Server address and Secondary DNS Server address for 'Servers'. Select a DNS proxy from the drop-down for the 'DNS Proxy Object' field and click on 'ok'.
Now we have to configure the date and time settings. In the NTP tab, enter the hostname or IP address of your Primary NTP Server and click on 'ok'. Let's configure the general firewall settings now.
