It may dummy question but want to understand how the ICMP works in 6500 CSM module. what configuration required to be able to ping to the real server from client?
-client=1.1.1.0, has MSFC interface
-server=2.2.2.0, no MFSC interface
-6513 routing table=ip route 2.2.2.0 255.255.255.0 1.1.1.1
-->looks need the vserver with "any"(correct me if I'm worng) for the request traffic but how return the ICMP packet from the server.
!
vserver test
virtual 1.1.1.100 any
Thanks in advance,

in routing mode, the CSM will block traffic going directly to the servers.
To allow this traffic you need to create a serverfarm to ROUTE the traffic and associated this server farm to a catch-all vserver.
ie:
serverfarm ROUTE
predictor forward
no nat server
!
vserver catch-servers
virtual 1.1.1.0 /24 any
serverfarm route
inservice
!
The vserver should catch a subnet, not real host ip address.
The response from the server will be forwarded to the client because the ping request from the client will create/open the connection both ways.

Hello,
What's the answer for bridge mode? What's needed to ping directly from client to realserver and vice versa?
Your input is really appreciated.

David,
in bridge mode, if the client and server are in the same subnet, the client will send traffic directly to the server destination mac address and the CSM will bridge/forward the traffic.
