[Command] sysopt security fragguard [Description] 
Enables the IP Frag Guard feature, which is designed to prevent IP fragmentation attacks such as LAND.c and teardrop. This works by requiring responsive IP packets to be requested by an internal host before they are accepted and limits the number of IP packets to 100 per second for each internal host.
