  • First we need more information about the setup.

     

    • Are there only 2 servers behind the LTM?
    • Are they responding correctly when access directly?
    • Is the LTM placed inline in front of the servers or on the side (on-a-stick)? If on-a-stick, is Auto-map enabled on the Virtual Server?
    • Are the two server up or down from the LTM's point of view (red og green)?

    More detail is needed in order to help you.

     

  • Hi Phillip!

     

    Not to be a showstopper and force you to reconsider plans, but BigIP LTM 2000 hardware appliance is too weak to be worthwhile compared to BigIP VE. If you're not going for BigIP 4000 (previous gen) or better, I recommend to consider going for BigIP VE. At later time, BigIP VE can be scaled at ease, and any pre-owned BigIP VE licenses can be migrated to a public cloud such as Amazon AWS for better pricing. It's flexible and not less capable than 2000. Once BigIP 2000 no longer is enough for your production scale, it's basically a useless box which at best can help you in labs or test environments. For VM Hypervisors, Libvirt KVM is a great free option for BigIP implementations.

     

    In regards to config migration, your best bet is to do this work manually. It takes time, possibly a few days, but it's a one-time effort. There's a migration script available, but it certainly does not work perfectly. The way I see it, it's best to take it slow and do everything from a scratch instead of running that old script and then wasting possibly much more time trying to figure out stuff that script didn't convert correctly. Nevertheless, question was asked before here, for reference, Matthieu Dierick shared a link with script which may or may not help you with your task. Good luck with the project!

      most the service is UP, except TCP port 7004. So I don't need the scrip file. I need advice. how to adjust the parameter of the TCP profile.

      if I don't add virtual server in my ltm(ltm is transparent mode) the clint can access one server normally. however, it is not my required. because I have two server to be accessed.
