The NAT table is full. Resolution:

Reboot the Broadband Router by turning the power to the unit off and then on again. Some types of hacker tools use very non-standard data streams. Some of these streams may cause the Broadband Router to lock up. When the Broadband Router locks up, it will not affect the computers attached to it. You may need to restart the client computers to regain Internet access.

Although sometimes inconvenient, a lock-up is an indication of an attack. Part of the design of the Broadband Router is to act as a decoy for such traffic. If your computer is locked up instead you may have lost changes to open, unsaved files, lost data, or corrupted your operating system or hard drive.

If you are currently experiencing frequent lock-ups, you may wish to upgrade the firmware.
