Hi Steve;
Forgive the long post but
here is what I've got working for me:

*** loader.conf
# if_tap is compiled into the kernel
# but loading if_tap does it also
if_bridge_load="YES"

[END] ------------------------------------
Turned my desktop into a gateway.
No need to fiddle with sysctl at all !
The qemu-ifup script does everything that's needed.
With these configs, EVERYTHING works like a charm here.
Guests have internet, they see ALL the host's files, i can
ssh to the linux guest and remote desktop session with
the XP guest (I know it is "overheady" but it is doable).
Finally, qemu comand line:
/usr/local/bin/qemu -boot c -m 740 \
-hda '/Vmachines/qemu/sda.img' -hdb '/Vmachines/qemu/sdb.img' \
-cdrom '/dev/cd0' \
-net nic,vlan=0 -net tap,vlan=0,ifname=tap0,script=/etc/qemu-ifup \
-localtime -kernel-kqemu &
As you can see, I set aside specific tap names for each guest:
linux -> tap0
XP -> tap1
and so on...
I hope this helps
