Hi, I have some guests running in the "default" network (virbr0) and I've also created a similar (NAT) network (virbr1). Therefore, the FORWARD chain for the CentOS 6.4 host looks like this: http://fpaste.org/29229/75281379/ ...where line 3-7 are related to virbr0 and 8-12 to virbr1. My 2 questions: 1) I've noticed that I can ping from a guest within virbr0 to any guest on the virbr1 network. However, I can't do the same from virbr1 (ping guests on virbr0). This is because of "line 6" on the pastebin, where the traffic is REJECTED. I originally thought that If I create multiple NAT networks (just like the default virbr0) they would be able to talk to each other (the host doing the actual forwarding) but as you can see, based on the iptables rules that libvirt injects, this only happens for the first network. That is, the first network can reach all other networks (just because it happens to be the first one defined). Is this the intention (only default can talk to the others but not the other way around)? 2) I would like both networks to talk to each other. If I remove line #6 I can make virbr1 guests talk to virbr0 guests. What is the correct way to handle this? I obviously don't want to perform "iptables -D FORWARD line-number..." every time I start libvirt. (I really like to leave the networks as they are, NAT, dhcp running etc). Thanks!
