Configuring virtual servers

 

To anyone who can help me,

 

 

My understanding is that a virtual server allows traffic flow in one direction only. In most cases you would enable a virtual server to listen on a single external vlan.

 

Could there ever be a situation where you would enable the same virtual server to listen on two different external vlans? Or enable a virtual server on both an external and internal vlan?

 

 

Thanks

    What if for some weird reason 2.2.2.2 initiates a connection to virtual server 1.1.1.1. Will the virtual server just drop the packet, or will it forward the packet back to 2.2.2.2 since it is the pool that the virtual server is configured to load balance to?

    if virtual server 1.1.1.1 is enabled on internal vlan (i.e. 2.2.2.2 vlan), connection will be accepted and processed (i.e. send to 2.2.2.2). anyway, since client and pool member are in the same subnet, snat may have to be used to prevent asymmetric network path (e.g. client --(request)--> virutal server --(request)--> pool member --(response)--> client).
