From bb53fc5394201c0cbe3c89a1c9fa5fbd6a3b832c Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 22 Jul 2009 17:03:52 +0200 Subject: slirp: Fix guestfwd for incoming data Unless a virtual server address was explicitly defined (which is impossible with the legacy -net channel format), guestfwd did not properly forwarded host->guest packets. This patch fixes it.
