Oh, I reread this and it finally dawned on me....

"By default, guests that are connected via a virtual network with <forward mode='nat'/> can make any outgoing network connection they like. Incoming connections are allowed from the host, and from other guests connected to the same libvirt network, but all other incoming connections are blocked by iptables rules."

So, I changed the mode to "route" and I get the behavior I need for all the VM's and IPv4.

So....thanks once again.
