CSM Servers within serverfarm in different subnets?

[carlsond]

For some reason we thought there was an issue with this but no one can remember why.

We have a CSM in routed mode and would like to load balance between two servers in different subnets. Can this be done?

For example

VLAN 10 Client

ip address 192.168.10.1 255.255.255.0

VLAN 20 Server

ip address 10.1.1.1 255.255.255.0

VLAN 30 Server

ip address 10.1.2.1 255.255.255.0

natpool nat1 10.1.1.200 netmask 255.255.255.0

Serverfarm farm1

nat server

nat client nat1

real 10.1.1.10

inservice

real 10.1.2.10

inservice

Will this work and if not why??

Thank you,

Dave

Dave,

the problem is not the fact that the servers are in different vlan. The problem is the natpool.

The natpool could force the response from the server in vlan30 to come back in vlan20 since the natpool address is part of vlan20.

The CSM wants to see the response coming back on the same vlan it sent the traffic out.

If you can guarantee that servers in vlan30 will send their response to the CSM in vlan30 [maybe with a static route or setting the csm as default gateway], then this config will would work.
