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=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
status: active
tap0: flags=8943<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=41<UP,RUNNING> mtu 1500
tap2: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
media: Ethernet autoselect
# brconfig
bridge0: flags=41<UP,RUNNING>
Configuration:
priority 32768 hellotime 2 fwddelay 15 maxage 20
ipfilter disabled flags 0x0
Interfaces:
tap2 flags=2<DISCOVER>
port 7 priority 128
tap0 flags=2<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=3,ifname=tap2 -net
nic,macaddr=de:ad:be:ef:00:02 win.img
