Public bug reported:

I'm using 9.04 and libvirt-bin is of 0.6.1-0ubuntu5. I would like to
make port-forwarding setting easier.

With NAT network setup, a iptables FORWARD rule is created:

    0     0 ACCEPT     all  --  *      virbr0  0.0.0.0/0
10.1.1.0/24         state RELATED,ESTABLISHED

This rule, together with another 5 rules, prevent port-forwarding to
guest. What I need to do is to

1). Insert another rule before all these rules:

    12065 2170K ACCEPT     all  --  *      virbr0  0.0.0.0/0
10.1.1.0/24

2). Add a port-forwarding rule to PREROUTING table:

   10   576 DNAT       tcp  --  eth0   *       0.0.0.0/0
1.2.3.4      tcp dpt:22 to:10.1.1.1:22

Step 2 is simple, as I could preset it, save it using iptables-save and
restore it on every reboot. However, step 1 is not a clean way to
achieve port-forwarding. Could libvirt config allows port-forwarding?
