Re: lvs and direct routing question...does the real server have to be routable?

[tc lewis <tcl@xxxxxxxxx>]

i believe using unroutable/internal ips is fine for the "real" ips of the
real servers, but they need to be able to contact the client machine
directly, ie: have an outgoing gateway route to the "real" internet.

i may be missing something.

client

 v
director VIP (eth0)
         192.168.123.9 (eth1)
 |
 |
 v
real server 192.168.123.11 (eth0)
            (VIP on hidden interface/whatever)
 |
 |
 v
gateway 192.168.123.1 (eth1)
        re.al.i.p (eth0)
        allow 192.168.123.11 to forward through here...

 v
back to client.

right?

-tcl.
