I don't think it is a bug. When you create a pipe you decouple the layers in the output path, so the error message generated in the bottom part of ip_output cannot be passed back up because the caller is already long since gone. the PR can be closed. cheers luigi On Fri, Jun 18, 2004 at 02:07:29AM +0000, Bruce M Simpson wrote: > Synopsis: When created dummynet pipe on output router interface with lower MTU system stops to generate 'Fragment Needed but DF was Set' ICMP in cases when it must > > Responsible-Changed-From-To: freebsd-bugs->luigi > Responsible-Changed-By: bms > Responsible-Changed-When: Fri Jun 18 02:07:14 GMT 2004 > Responsible-Changed-Why: > Luigi is Mr. Dummynet > > http://www.freebsd.org/cgi/query-pr.cgi?pr=62957
