UDP Blast Protection Configuration Menu
Malicious attacks over UDP protocol ports are a common way to bring down real servers. Alteon can be configured to restrict the amount of traffic allowed on any UDP port, as a result ensuring that back-end servers are not flooded with data and become disabled.
You can specify a series of UDP port ranges and the allowed packet limit for that range. When the maximum number of packets per second is reached, UDP traffic is shut down on those ports.
Alteon supports up to 5000 UDP port numbers, using any integer from 1 to 65535. The maximum port range is 5000. If the first port number is 300, the last number that can be used is 5300. While you can configure multiple port ranges, the sum of ranges cannot exceed the maximum of 5000 ports.
