[lvs-users] ipvs not forwarding packets and pushing to directors input interface

Hi,

I've run LVS/NAT several times, always successful, right now faced problem:
ip_vs is active, but all incoming packets are facing INPUT/director server
interface instead of being forwarded to realservers.

serial_no = 29
primary = 123.123.123.251
service = lvs
backup_active = 0
backup = 0.0.0.0
heartbeat = 1
heartbeat_port = 539
keepalive = 6
deadtime = 18
network = nat
nat_router = 172.16.112.251 br5:1
nat_nmask = 255.255.255.0
debug_level = 7
monitor_links = 0
syncdaemon = 0
syncd_iface = br1
syncd_id = 0
virtual web2_80 {
     active = 1
     address = 80.92.177.252 br1:1
     vip_nmask = 255.255.255.240
     port = 80
     persistent = 100
     use_regex = 0
     load_monitor = none
     scheduler = rr
     protocol = tcp
     timeout = 15
     reentry = 12
     quiesce_server = 1
     server web2b {
         address = 172.16.112.52
         active = 1
         port = 80
         weight = 50
     }
}

kernel net.ipv4.conf.*.forwarding all set to 1

[root at node1 ~]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  123.123.123.252:80 rr persistent 100
  -> 172.16.112.52:80             Masq    50     0          0

only difference i see in current configuration - bridged interfaces

Centos 6

I don't even know what and where to check and debug, everything should
work...
