CSM in routing mode

Hi,

I've a CSM configured in routed mode.

I've also vserver with direct access in order to permit the management of the real servers.

The question is: "Is there a way to block the communications between servers in different serverfarms?".

Thank you.

Best regards.

Massimiliano.

There is no way to filter traffic.

What you can do is create a vserver to catch the traffic you want to block and send it to a real that does not exist.

Hi Gilles.

Thank you..

Can you give me an example in order to implement your solution.

Best regards.

Assuming you have 2 vlans x and y.

Subnet of vlan x is x.x.x.0/24 and subnet of vlan y is y.y.y.0/24

If you want to block traffic from vlan y to vlan x, implement the following vserver.

serverfarm NULL

real x.x.x.252

inservice

vserver Block1

virtual x.x.x.0 /24 any

serverfarm NULL

vlan y

inservice

You have to make sure x.x.x.252 does not exist !!! This whill blackhole the traffic.

Hi Gilles,

An upgrade (hardware or software) could help to avoid communications between different servers in differeny server farms.

Thank you.

Best regards.
