Block Fragmented IP Packets

"With this feature enabled, all packets are checked to determine if the packet contains a

"fragment" flag. If the flag exists, the CM will discard the packet. This feature is used primarily to

protect against any intruders/hackers from gaining access to the router or network." "Under

certain conditions, this feature may cause communication issues with other devices on the

network and should be disabled. For example, streaming media applications may fragment the

packets depending on the encoding used for the video stream. Depending on the encoding used for

the clip, some or a majority of the packets will become fragmented. For clips encoded at 300 Kbps,

66% of the packets are IP fragments, while below 100 Kbps there is no fragmentation.
