This is my opinion as well.

I have tried to lower MTU. Without success so far.
I may try MSS as well, but as far as I know MSS is only relevant for
TCP not UDP (which is used by IKE).
BTW, should MSS/MTU be lowered at both sides of the tunnel or is it
enough when this is done at the Mobile Modem side?
Thanks for the link.
