OK, that makes sense.
So what could be stopping the real server from responding?

This is the output of my ipvsadm
ns0:/etc/ha.d# ipvsadm -ln
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  x.155.167.196:80 rr
  -> x.155.167.242:80           Tunnel  1      0          2         
TCP  x.155.167.195:80 rr
  -> x.155.167.226:80           Route   1      0          0         
  -> x.155.167.227:80           Route   1      0          0         

Note that the VIP 195 is working fine using the Route method.

This my ipconfig on the real server
tunl0     Link encap:IPIP Tunnel  HWaddr   
          inet addr:x.155.167.196  Mask:255.255.255.255
          UP RUNNING NOARP  MTU:1480  Metric:1
          RX packets:39 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:1872 (1.8 KiB)  TX bytes:0 (0.0 b)

Note that it is receiving data
