We have a situation as a result of going through a PCI audit. We have a single subnet which contains a handful of servers that need to be isolated and traffic restricted. Originally we were going to move these few servers to a new switch VLAN changing the IP scheme and use the PA to permit/allow traffic between that new vlan and the existing subnet and internet. Now it looks like it is going to be pain since there are a lot of changes that will need to be done to these few servers to change the IP. Worse yet is that the vendor is on a service blackout as a result of being purchased by Oracle. So there is no time before our deadline to get assistance from them before we will be fined for not being in compliance.
My thought was to create a virtual wire where traffic would ingress to the PA from the existing LAN-VLAN (Client-SIde) and egress on the interface of the virtual wire (Server Side) so I can apply rules to all traffic bound to/from those servers. Seems like it should work in my mind, but wondering if I'm on the right track or is there is a better way to isolate these few hosts to lock them down.
Hopefully this makes sense. I can do a visual if needed.
