(Apologies for missing this part of your message in my previous
reply...) Good point. This is what the Appendix is trying to
say. Just to clarify... the above option was included for
completeness. In cases where the security gateway cannot
determine the originating source, the Appendix recommends the
that the security gateway "hold the PMTU information until
another too-big packet arrives and then use that packet and the
PMTU information to construct a ICMP PMTU for the originating
host (H0).
Thanks again,
Karen
