Basically, I'm using the RHCS, because I use Centos in my production 
servers, and for me it's the easy way, and I have the LVS with two 
servers: the primary and the backup server(I need high-availability)

I'm trying to do a LVS (NAT), with different NICs (one for all the 
public services, and one private for every service), because I need to 
have the traffic separated for every service in the private part. This 
is easy to do with the RHCS, but the unic problem is that I only can 
configure one gateway for the VirtualServer (the IP that you have to 
configure as the default gateway in the Real-Servers). Because that, 
there is only one real-server that I can configure the gateway, for the 
others I can't put this gateway because there are in another subnet and 
I can't confgiure a gateway from a different subnet.

It's easy to do that directly with LVS? How?
