Odd... are you using GRE for the return traffic as well? I am not really
sure how things pulls together on the host side when using the gre
module..

Probably not. To work around MTU problems by lowering the MTU you need
to address it at the side seeing the problem, not the side causing the
problem. To work around it at the side causing the problems you need to
increase the MTU.
