Subject: [Qemu-devel] [PATCH] [slirp] Accept packets with TTL=1
Date: Mon, 13 Sep 2010 23:01:30 +0200 [thread overview]
Message-ID: <1284411690-3557-1-git-send-email-hpoussin@reactos.org> (raw)
Packets with TTL=1 may be directed to local network (DHCP/DNS servers for example), so don't discard them
This is required by old versions of NetBSD which send DHCP DISCOVER packets with TTL=1
