SNAT / Masquerading problems using LVS-NAT

[Rudd, Michael]

My current setup has 1 director and 2 servers behind it. Heres the dump
from ipvsadm. 
 
[root at jackets-a sysconfig]# ipvsadm
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
UDP  192.168.67.213:domain rr ops
  -> dnsa-c:domain                Masq    1      0          110935    
  -> dnsa-d:domain                Masq    1      0          110934

LVS is working the way it should except return packets are not the
correct source IP address. They should be from 192.168.67.213 which is
the address of the service. Instead they are the address of the real
server. This worked in kernel 2.4 when I tested it 2 months ago. Now its
broken in my 2.6.18 kernel. 
 
Heres also a dump from ip addr. We are doing our dns traffic based on
bond1.201.

I've tried the ip_route_me_harder patch I found here
http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.LVS-NAT.html#brow
nfield but it doesnt appear to work correctly at least for me. Anybody
got any clues as to what broke in 2.6 for this?
 
Thanks
Mike
