    We have to change our internal ip addressing scheme, and I was
    wondering if someone can tell me if I can have 2 ip addresses on our
    internal interface on our cisco pix firewall.

    What we have in mind is to bind 2 ip addresses to all of our servers
    nic's, and then also have 2 ip addresses on our pix firewall and
    eventually get rid of all our old addresses and just have the new
    scheme. If anyone has had to ever change there internal ip addressin
    scheme and have any insight on the best way to accomplish this I would
    love to hear your ideas.

    Thanks for you help.

    Please refer to my posting of a couple of weeks ago,
    http://groups.google.ca/group/comp.dcom.sys.cisco/msg/f2a4c986aa90ab00

    To which I would add: it's easier if you have LAN router to route
    between the two IP spaces as long as you are in transition.
