Hi, I just notice that iptables -A FORWARD -s 192.168.0.1,192.168.0.2 -j ACCEPT give us: iptable-save -A FORWARD -s 192.168.0.1/32 -j ACCEPT -A FORWARD -s 192.168.0.2/32 -j ACCEPT So, maybe can we forbid iplist in vm rules ? (now we have ipset for this) (I also find a bug with --src-range, I'll send patch)
