MSN blocking PMTUD

Mon May 17 15:07:08 UTC 2004

Hi, it seems that Microsoft Network is blocking the path MTU 
discovery (ICMP fragmentation required but df bit set).

That is causing problems because some customers who happen to 
use GRE tunnels for their branch offices can't access MSMessenger 
of the Hotmail page.

Is there somebody from MSN here? Is there a workaround for this 
problem without using other type of tunneling? If not, is there any 
other workaround?
