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?
