Service Center and Upgrades
I have exceeded my node limit. What does this mean? What should I do?
Your Product Key specifies a maximum number of nodes that you may connect to the
ZoneAlarm router.
The ZoneAlarm router tracks the cumulative number of nodes on the internal network that
have communicated through the firewall. When the ZoneAlarm router encounters an IP
address that exceeds the licensed node limit, the My Computers page displays a warning
message and marks nodes over the node limit in red. These nodes will not be able to access
the Internet through the ZoneAlarm router, but will be protected. The Event Log page also
warns you that you have exceeded the node limit.
To upgrade your ZoneAlarm router to support more nodes, purchase a new Product Key.
Contact your reseller for upgrade information.
While trying to connect to a Service Center, I received the message “The Service Center did
not respond”. What should I do?
• If you are using a Service Center other than the Check Point Service Center,
check that the Service Center IP address is typed correctly.
• The ZoneAlarm router connects to the Service Center using UDP ports
9281/9282. If the ZoneAlarm router is installed behind another firewall, make
sure that these ports are open.
