LVS -Apache - Cannot browse page

 Dear Anyone,

              I had setup a LVS Apache Web server cluster with 4 machines(2* LVS routers + 2* Webservers).OS is RHAS 2.1 and I used Piranha Configuration tool and I believe I have configured as same given in  LVS/Piranha documents.Finally when I am browsing for the web page by giving Virtual IP in the browser(Internet explorer),it doesn't return any page.Apache is found as  running when checked locally from web server.Here is my LVS.cf file given below.

serial_no = 104
primary = 151.8.24.124
primary_private = 100.100.0.3
service = lvs
backup_active = 1
backup = 151.8.24.125
backup_private = 100.100.0.4
heartbeat = 1
heartbeat_port = 539
keepalive = 15
deadtime = 18
network = nat
nat_router = 100.100.0.254 eth1:1
nat_nmask = 255.255.0.0
reservation_conflict_action = preempt
debug_level = NONE
virtual http {
     active = 1
     address = 151.8.24.150 eth0:1
     vip_nmask = 255.255.0.0
     port = 80
     send = "GET / HTTP/1.0\r\n\r\n"
     expect = "HTTP"
     load_monitor = ruptime
     scheduler = wlc
     protocol = tcp
     timeout = 6
     reentry = 15
     quiesce_server = 0
     server webserver1 {
         address = 100.100.0.1
         active = 1
         weight = 1
     }
     server webserver2 {
         address = 100.100.0.2
         active = 1
         weight = 2
     }
}



 I believe you can help me.

Thanks a lot
