There is only one director, I just re-configured it so that local node is 
127.0.0.1 as per Joe's email:

IP Virtual Server version 0.8.1 (size=65536)                   
Prot LocalAddress:Port Scheduler Flags                         
  -> RemoteAddress:Port             Forward Weight ActiveConn InActConn
TCP  10.122.15.41:80 rr
  -> 192.168.0.2:80                 Masq    1      0          0         
  -> 127.0.0.1:80                   Local   1      0          0     

Machine 1 is director and apache. Machine 2 is just apache.

ifconfig on Machine 1 gives:

1) Where is the netmask wrong?
2) What do I do to configure my NAT Router? What do I need to set up externaly 
to the LVS stuff to have it work?
