Hi! I observe a strange thing. When I create 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. If I create this pipe on incoming interface there is no problem. I check this on many routers under 4.8 and 5.2 FreeBSD. Is this a bug or feature? :) How pipes can be created leaving ICMP generation working? -- Alexander Motin
