System: NetBSD grittykitty.sixgirls.org 4.0_BETA NetBSD 4.0_BETA (GRITTYKITTY-$Revision: 4.004 $) #1: Fri Sep 8 00:06:45 UTC 2006 john@shiva.ziaspace.com:/usr/obj/sys/arch/macppc/compile/GRITTYKITTY macppc
Architecture: powerpc
Machine: macppc
>Description:
When net.inet.ip.hostzerobroadcast is set and when a host is at the base
address of a subnet, communication works except from machines behind ip
filter's NAT. See:
http://mail-index.netbsd.org/tech-net/2006/09/13/0003.html
>How-To-Repeat:
Put a host at the base address of a subnet. On another machine which is on
the same subnet, set net.inet.ip.hostzerobroadcast=1. Try to communicate
with the host at the base address from somewhere that is behind NAT on the
other machine.
>Fix:
None known.
