Crikey is that a single 256K packet!?
I presume this is for IPv6 as IPv4 only supports 64k.
I suspect that Globalscape's server will probably break in other ways
sending packets this big especially as the network gets busy. I would
strongly suggest that they look to fix this.
I'm not sure of the value of exceeding 64k at the moment... Essentially
this is just turning off the check for IPv4 anyway.

PS
For reference the current gigabit switches with jumbo frame support can do
just over 8K (and their not likely to get bigger than that). Slower
switches do 1500 bytes.
