"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.
