Good advice, but why use a bridge interface _at all_ in this case?
I have the following in /etc/network/interfaces:
iface tap0 inet static
address 192.168.0.1
netmask 255.255.255.0
pre-up iptables-setup-for-masq
and in my qemu-ifup (or rather kvm-ifup):
#!/bin/sh
/sbin/ifconfig $1 0.0.0.0 up
/sbin/ifup $1
exit 0
and that is all.. No more need for any bridging.
BTW I think it would be an important feature to also have
a qemu-ifdown / kvm-ifdown script to remove the iptables
rules after the tap device disappears.
Regards,
Wolfram.
