Also: if the don't fragment bit has been set by the source application
the packet will not get past the first router needing to fragment it. You
used to see this going from Token-Ring to Ethernet and now it can be an
issue with IPSEC, where most of the original packet gets into one packet,
but beacuse of the hearders a second packet of just a few bytes has to be
also sent. Some apps set the "don't fragment bit" and have problems
accross the VPN.
