[f-nsp] Foundry ServerIron - source-nat

[Gaurav Sabharwal]

Hi,

We have a ServerIron XL Load Balancer on which we do SLB for mysql and 
http. We have source-nat enabled. In order to get the client IP address 
in the log file for statistics, etc. I wanted to disable the source-nat 
for one particular VIP compromising of two real servers.

After disabling the source-nat from the real servers, the traffic to the 
real server stops. Below is the relevant configuration.

server real server1.test.com 192.168.254.2
  port http
  port http url "HEAD /"
!
server real server2.test.com 192.168.254.3
  port http
  port http url "HEAD /"
!
server virtual www.test.com 192.168.254.1
  predictor least-conn
  port http sticky
  bind http server1.test.com http server2.test.com http

The configuration works fine if I add the source-nat command to the real 
servers. global source-nat is not enabled.
