Hello!
I have set-up four nodes system: two LVS load balancers (CentOS) and
two working nodes (openSUSE).
LVS nodes have global IPs, so they able to access the internet and
working nodes have only private IPs, so they cannot access internet
directly. I use NAT-base load balancing.
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?
You should read thru the LVS HowTo, more about LVS-NAT. There is no
reason why your LVS load balancers can't also act as general NAT
gateways, that's really what they're already doing. Just make sure your
LVS-NAT gateways are masquerading internally initiated outbound traffic.
I don't think you'll have a problem.
