Well, there's the case where fragments can be fragmented further, the RFCs support that. The question is whether anyone would sanely set the DF bit on a fragment to prevent _further_ fragmentation. You have to consider fragmentation of fragments in context of PMTU and then compare all of this to Linux NFS setting DF on all (unfragmented) packets, and the reasons they do that (which is not fragmentation of fragments at all). > notheless you can just "scrub in all no-df". That won't work for him, as the check in question happens before no-df is applied. Daniel
