New Features

·New SmartDefense Protection: Checksum Verification
When this protection is enabled, SmartDefense will identify and drop IP, TCP, or UDP packets with incorrect checksums.

·New SmartDefense Protection: Urgent Flag Clearing
The URG flag is used to indicate that urgent data exists in a TCP stream, and that the data should be delivered with high priority. Since handling of the URG flag is inconsistent between different operating systems, allowing the URG flag may enable an attacker to conceal certain attacks.

By default, SmartDefense automatically clears the URG flag to ensure security. To allow the URG flag, in the SmartDefense tree's TCP > Flags node, set the URG Flag field to Allow. To prevent the URG flag from being used, set the URG Flag field to Clear.
