I have changed the MTU value for eth0 on the director to 1400. All that does 
for me is make more machines (all that I have tested) suffer from the same 
problem.

Should the MTU value be changed at different places? I.e. both ends of the 
tunnel?

Hello Horms,

... or the mtu of the tunnel's routing entity for that matter. This is faster 
and less intrusive than adjusting down the whole physical interface's mtu. I 
use 
it for boxes where I have dozens of VPN tunnels over a physical interface but 
also non-tunneled traffic.
