Hi Bob,

Sure, my current employer is a BTW customer and I have checked our
live/current set-up and L2TP sequencing is disabled. I also worked for
 different UK operator previously that was also a BTW customer. I've
checked the old configs and outputs from when I was there, and again
L2TP sequencing was disabled (I'm in close contact with those former
colleagues they confirm it is still disabled). I've asked a few
friends at other UK operators, and none of them have L2TP sequencing
enabled on their BTW tunnels. I've also scanned the BTW docs and can't
find anything that mentions it is supported.

Cheers,
James.
