so, this is supposed to work, right? does it work for you? or am i
missing something here? i have tried various drivers (kernels, indeed).
suse 9.2, latest knoppix...   same problem there.

maybe it's the tun-driver of my host kernel. i have ubuntu hoary with
stock kernel 2.6.9-1-686 here. firewall tables are all clean on host and
guest, i have checked this already with iptables -L.
