Block Fragmented IP Packets – from the UBEE Router Document
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. 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. For clips encoded at 300 Kbps, 66% of the packets are IP fragments, while below 100 Kbps
there is no fragmentation.
In the Firewall section, the default setting is Enabled as shown by the check in the box below:
