[lvs-users] LVS working, just not load balancing.

["Ray W. Johnson" <raywjohnson@xxxxxxxxx>]

Greetings All,

I have a working setup of one director and two real servers. All servers 
are running and pulse daemon starts fine. I can HTTP, FTP, and SSH to 
all servers. The "virtual server" is behind a router/firewall that 
handles real/public to local IPs.

I suspect I have something backwards somewhere. Here is the setup/config.

D01 (director): http://208.90.226.39/
(no backup yet)
P01 (real # 1): http://208.90.226.30/
P02 (real # 2): http://208.90.226.31/

BUT... no load balancing.

Surf to : http://208.90.226.39/index.html and you get "D01"
Should switch between: "P01" and "P02", right??

( http://208.90.226.30/index.html == "P01" / 
http://208.90.226.31/index.html == "P02" )
