These are questions that were asked of me. After searching the documentation and not finding an answer I thought to ask everyone here to see if you have done this.
Is there a way to download the operating system of the VPN Concentrator from the Concentrator to a TFTP server or other device? The current version of VPN Concentrator is no longer available on CCO. Thus if we wanted to back out of an upgrade we currently do not have a copy of the *.bin.
The above brings a second question.
Can a VPN Concentrator be downgraded in version? If it can how many versions or times can it backed down. I know with an IDS you can back out one step. Is this the same with a VPN Concentrator?
Any help would be appreciated.
