Hi,

Still having a bit of trouble with the correct routing from my real 
servers back to my client through the load balancer, trying to update 
the windows routing table to make it send all replies through the LB, 
here is what it looks on one of the real servers (its the same on the 
other):
LB IP is: 172.16.5.126

C:\Documents and Settings\Administrator>route print

I have tried to run the command:
route change 172.16.5.0 mask 255.255.255.0 172.16.5.126 metric 1
but what I get is:
The route specified was not found.

What I got on my LB is as follows (my IP being 172.16.5.17):

This is all because I need them all on the same network and you have 
already kindly explained to me that this is happening cause the real 
server has access to directly respond to my client via the same network, 
but it seems I can not change that for some odd reason >.<

Any ideas?

Thanks
