Thanks, So can one make the assumption that a datagram is a normal packet
like an http packet and ICMP Destination Unreachable is sent to the sender
if the http request can not be made? This was my original problem not really
knowing what it meant by datagram and the rfc isn't that helpful on the
subject.
