I have 1 ACE appliance which running in routed mode. There are 2 vlans which are client vlan and server vlan. My VIP subnet is same as server vlan subnet. I would like to Source Nat each farm of servers orignated traffic to their own VIP. I have tested to ping from server vlan's server to client vlan's PC but the "show xlate" didn't show NATing and Packet Capture at client vlan's PC also showed that the source IP from server is not NATed. I have configured as the following but is not working, can any expert help me to look at my config whether I got miss out something:
To answer your latest questions.
Yes, the service-policy must be configured on the interface facing the server (inbound interface) and the nat-pool must configured on the outbound interface.
Also note that we do not nat bridged traffic.
I don't think the show xlate will show any entries when pat is configured.
You should check with a 'show service-policy' if you have any hit on your class-map NAT-POLICY.
Also, do a 'clear conn' before your test or use telnet instead of ping.
All your icmp traffic from 1src to 1 dst will fall under the same flow.
If the flow was created before the nat policy, there will be no nating until the flow times out which can tale a long time for icmp.
