--- Comment #24 from George V. Neville-Neil <gnn@FreeBSD.org> ---
Thanks for the update and the new files. I am trying to reproduce this on =
HEAD
still. With your latest test were you still using IPFW and NAT or was this
just vanilla forwarding? I have setup some test hosts in the lab
The setup is:
172.16.0.1 172.16.0.2 172.16.1.2 172.16.1.3
source <-> router <-> sink=20
1500 576
and I'm doing a ping -s 1024 -D 172.16.1.3 and I do see the MTU error retur=
ning
on the source:
36 bytes from 172.16.0.2: frag needed and DF set (MTU 576)
Vr HL TOS Len ID Flg off TTL Pro cks Src Dst
4 5 00 041c 0000 0 0000 3f 01 debc 172.16.0.1 172.16.1.3
Your hardware addresses in the pcaps are obfuscated so its hard to tell wha=
ts
happening at layer 2.
