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.
