[lvs-users] Lvs for multi-site/subnet terminal services

I switched target boxes because I didn't want to mess around with network
stuff on a production box.  Anyway I created the loopback adapter on my
target box, set it to have the VIP with the netmask 255.255.255.0.  I tried
it with no gateway, the gateway of my physical NIC, and my physical NIC's
IP.  I assume being a local loopback it doesn't need a gateway but I'm quite
confused about the whole thing.  It seems like it¹s getting to the target
box but the response is going no where.  Here is my config on my LVS box.

root at template:~# ifconfig
eth2      Link encap:Ethernet  HWaddr 00:50:56:ad:40:e6
          inet addr:10.14.2.157  Bcast:10.14.2.255  Mask:255.255.255.0
          inet6 addr: fe80::250:56ff:fead:40e6/64 Scope:Link

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          Interrupt:18 Base address:0x1424

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:842 errors:0 dropped:0 overruns:0 frame:0
          TX packets:842 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:160192 (160.1 KB)  TX bytes:160192 (160.1 KB)

10.14.2.158 is the VIP.

This is the setup of my target terminal server.  First the local loopback
then the physical nic.
