routing problem with lvs?

[Martin.Zehetmayer@xxxxxxxxxxx]

Hi, 

I have a problem in setting up a piranha load balancer with 2 real servers
(http). I've set up the 
configuration below which contains one load balancing server and two real
servers. pulse is 
starting all processes correctly and all interface come up and are pingable.
When I connect to the virtual ip on port 80  (telnet 192.168.0.50 80) there
is no connection refused
but I also get no prompt from one of the webservers. 

Do I have to configure some external routing via iptables? What can I do to
check if the
routing from ipvs works? 


Thanks in advance,

Here is my configuration:
----------------------------------------------------------------------------
--
ipvsadm-1.21-9.ipvs108
piranha-0.7.6-1

Linux version 2.4.21-15.0.2.ELsmp


lvs.conf:
-----------
serial_no = 57
primary = 192.168.0.10
primary_private = 172.24.158.10
service = lvs
backup = 0.0.0.0
heartbeat = 0
heartbeat_port = 539
keepalive = 6
deadtime = 18
network = nat
nat_router = 192.168.1.11 eth2:1
nat_nmask = 255.255.255.0
debug_level = NONE
virtual wwwgroup {
     active = 1
     address = 192.168.0.50 eth1:2
     vip_nmask = 255.255.255.0
     port = 80
     send = "GET /test.html\r\n"
     expect = "statusok"
     use_regex = 1
     load_monitor = none
     scheduler = wlc
     protocol = tcp
     timeout = 6
     reentry = 15
     quiesce_server = 0
     server www1 {
         address = 192.168.1.30
         active = 1
         weight = 1
     }
     server www2 {
         address = 192.168.1.31
         active = 1
         weight = 1
     }
}

from the loadbalancer (192.168.0.10)
ping to 192.168.1.30 and 192.168.1.31 works (real servers)
ping to 192.168.0.10 works (primary)
ping to 192.168.1.11 works (nat router)
ping to 192.168.0.50 works (vip ip wwwgroup)

standard gateway for all real server is the nat router ip (192.168.1.11)
