My first instinct is to blame their firewall for not allowing enough ICMP stuff back through to let Path MTU Discovery work. But there's little to go on other than it being related to the amount of data and occurs in only one direction, so it's a guess, as I can't think of anything specific to SIMS that would cause it. I imagine you've already rebooted the Macintosh to rule out something in the OS getting flaky. ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
