Can't tell you anything new, and I had no problems of this kind (ever), and I don't see any way in which your MTU should change just like that, but I have to agree with Yedidyah - Your problem description sounds like a text-book case of misconfigured MTU, and ping -s would tell you everything you need to know -- Oded ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
