Now I need to know how give working nodes ability to access the
internet? I ask this because I don't know how to write properly iptables
rules so LVS balancing packets will not conflict with working nodes
internet connections. Should I assign some IP-alias for default gateway
for that nodes or something else?
make sure you can route the outbound traffic through the lvs cluster and
then nat it to the external pool IP of that cluster
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s some_internal_IP -o eth0 -j SNAT
--to-source the_public_cluster_IP
you can add as many of the second lines as you see fit depending on how
many internal boxes you have.
Also remember that the default route for the internal boxes should be an
IP that is floating so that in the event of one of your LVS's crashing
you can still route outbound.
Hope that helps
