[libvirt-users] routed mode

Hi, I have installed a centos65_guest_1 system on a centos65 host with virt-manager. By default libvirt has a default network in NAT mode. At centos65_guest_1 when pinging to google it works. But I would like to use a routed mode for production enviroment with some services online, like http, ftp, ssh, etc. I have created the virtual network 192.168.100.0/24 with routed mode, and I have installed another guest system, centos65_guest_2, that is using this network. The problem is that I can't ping to the outside world. ping to 192.168.100.1 is working Why is not working? Any suggestion? Thank you
