Using PF, the VM now can go to the Internet.
The thing is I'm not able to ping/TSE from the "real" workstation to the
VM. Is this expected as I am using on a tap interface ?

Here's what I did :
# ifconfig
wpi0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        status: active
tap0: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
	media: Ethernet autoselect
	inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.25
bridge0: flags=3D41<UP,RUNNING> mtu 1500
tap2: flags=3D8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
	media: Ethernet autoselect
# brconfig
bridge0: flags=3D41<UP,RUNNING>
	Configuration:
		priority 32768 hellotime 2 fwddelay 15 maxage 20
		ipfilter disabled flags 0x0
	Interfaces:
		tap2 flags=3D2<DISCOVER>
			port 7 priority 128
		tap0 flags=3D2<DISCOVER>
			port 5 priority 128
	Address cache (max cache: 100, timeout: 1200):
# qemu command (running Windows XP, NIC configured as 192.168.0.20)
qemu -m 512 -boot c -net tap,fd=3D3,ifname=3Dtap2 -net nic,macaddr=3Dde:ad:=
