I do all my development and testing on a slackware machine. I don't have
any idea of how RedHat does their stuff.
Setting up an LVS is difficult. If it doesn't work you can spend forever
trying to figure out what's wrong. I've incorporated all my mistakes into
checks in the configure script. WOuld you mind trying this conf file on
your setup? I assume you only have 1 NIC on the director - if you have 2
NICs just make sure the VIP is assigned the correct NIC (here eth0).
You will have to put the director-inside IP onto an alias somewhere on
the director (the script looks for this IP to tell if it's running on
a director or real-server).
I have all my IPs in /etc/hosts. For this example you can replace the
strings "sneezy","bashfull","lvs","director-inside" with the IP's.
I think I translated your IPs/network into this file. Please have
a look to see if its OK. I didn't have the IP for your 2nd real-server.

this sets up telnet.
you make an rc.lvs_tun file by doing
./configure-lvs.pl lvs_tun.conf
you run the rc.lvs file on the director, and then the real-servers.
If you get any error messages that you can't correct, send the output
of the rc.lvs file to me and I'll see what I can do.
