Defense Enable
Enable to prevent Ping-of-Death attack to the device. The default setting is
disabled. To enable or disable it, click on the check box for the LAN or WAN

Under "Custom Firewall Settings", users could create new rules to accept, reject or drop certain traffic going
through the UCM6200. To create new rule, click on "Create New Rule" button and a new window will pop up for
users to specify rule options.
Right next to "Create New Rule" button, there is a checkbox for option "Reject Rules". If it’s checked, all the rules
will be rejected except the firewall rules listed below. In the firewall rules, only when there is a rule that meets all
the following requirements, the option "Reject Rules" will be allowed to check:
• Action: "Accept"
• Type "In"
• Destination port is set to the system login port (e.g., by default 8089)
• Protocol is not UDP
