Hi all,
I have installed a CentOS 5.3 x86_64 server with kvm and libvirt to do
some tests for future virtualized deployments.
My environment:
eth0 --> 172.25.50.1/24 ("public" host ip)
virbr0 ---> 192.168.122.1/24 (natted interface installed by libvirt)
virbr1 ---> 172.26.50.0/24 (isolated internal virtualized network,
whithout physical interface binded)
Between 192.168.122.0/24 network and 172.26.50.0/24 network I have
installed a virtual firewall. So to reach 172.26.50.0/24 network, all
connections needs to go to 192.168.122.0/24 network.
I need to insert some iptables rules to allow access to some services
installed on 172.26.50.0/24 network like smtp,http,ftp, etc.
How can I configure libvirt to forward and nat these services coming
from 172.25.50.0/24 network to a specific IP under 192.168.122.0/24
network?? Or do I need to use /etc/sysconfig/iptables configuration and
disable libvirt's iptables rules ?? Some examples, please??.
many thanks.
