Re: Using LVS for servers on same subnet with real serverslistening on different ports

[Bruno Vincent <bruno.vincent@xxxxxxxxx>]

Hi,

i have just read this thread and i must confess i get really scared: I 
actually defined an architecture i have to implement now and i am 
wondering wether everything i designed is wrong!
I want to use a LVS-NAT director that load balances HTTP requests 
between two web server instances that are hosted on the same physical 
machine (which is a Solaris one). So i want to balance between RIP:80 
and RIP:8080. As far as i can read, it just cannot work.
Maybe i have a solution: if i set up a virtual IP on my realserver and 
then load balance between Real_Server_Real_IP and Real_Server_Virtual_IP 
do you think it can work ??
Many thanks,

Bruno
