How do you setup a private virtual firewall with the Cisco ASA 5510?  We have several servers behind a shared ASA 5510 and want to give remote access to change the firewall just for a certain group of those servers to a client, can this be done?

    You will need to change the mode of the ASA to multiple from single mode.

    ASA(config)#mode multiple

    Yes this can be done, there is more planning here though, how many interfaces do you have?

    What do mean shared ASA? Who has administrative control?

    If you do not have extra interfaces for this Firewall context (virtual) setup then we can share
    physical interfaces however give each logincal interface a seperate IP. There will be some firewall changes as well as changes to the network devices they connect to (in the case of shared interfaces). This will also require down time if the firewall is not already in "multiple mode".
    This can be completed thugh with minimal downtime,

    so you will have to know how many interfaces before you can finish? We are a dedicated server hosting company and want to be able to offer a virtual dedicated firewall. So new users would be added at diffrent times. If that is not possible without downtime each time then it will not work.
