Hello Gaurav,
I don't know if any of this will help, but when I was looking over
your configuration I had a few questions. First of all, I assume that
the ServerIron is in layer-2 mode, and that there is only a single
vlan - vlan1 in which everything resides ( real & virtual servers and
default gateway ). With that in mind, my questions were:
a/ for the real/virtual servers in the 74.53.217.x subnet, how do
these hosts reach the default gateway (50.1.1.129) ?
b/ for everything that is in the 50.1.1.x subnet, would it not be
correct for the ServerIron to send each of the real-servers an ICMP
redirect to its default-gateway ( which is on the same subnet as the
real-servers themselves ) ? If this were the case, then the
ServerIron would never see the return path traffic from the real-
servers.
Good luck in finding the issue.

Hi Mischa,
Thanks for the reply. The config. is attached. All servers point to
the LB as the default router.
I will try to upgrade later in the evening today.
Thanks,

Hi Gaurav,
Do you have a network setup and config for us?
One other suggestion, see if you can upgrade to 7.4.01m.

Hi,
Yes. The traffic is routed via the ServerIron.
Thanks,
Gaurav

Hi Guarav,
Are the flows send from the server to the client going through the
ServerIron somehow?

Some time ago, we had to enable source-nat on the LB. Now we are
trying to disable source-nat on the LB. When we disable the
source-nat
on the load balancer, the VIP does not responds to the HTTP
connections.
tcpdump on the server confirms that the packets are reaching the
server and are being sent back. However nothing reaches the web
browser.
