load balancing printer traffic

Hi

 

 

I have a fastl4 VS with two print servers in the backend pool. the problem is i can access the print servers on port 445 but i can't install a printer. if i connect derectly to the backend it works fine. i also have a folder with drives on the same server that i can access copy install from without a problem so i can't see what i am missing..

    Got it working if anyone is interested this is how i did it...

     

     

    VS configuration on F5

     

     

    ltm virtual vs_bc_printing {

     

    destination 10.237.0.1:any

     

    ip-protocol tcp

     

    mask 255.255.255.255

     

    partition BRC

     

    persist {

     

    /Common/source_addr {

     

    default yes

     

    }

     

    }

     

    pool pool_bc_citrix_printers

     

    profiles {

     

    FastL4_Print { }

     

    }

     

    rules {

     

    LB_logging

     

    }

     

    snat automap

     

    translate-port disabled

     

    vlans-disabled

     

    }

     

     

    In conjunction to this a loopback adapter will need to be created on the Wintel server (no reboot is required for this setup and the commands must be run to activate the adapter..)

     

     

    Click Start, select Run and enter hdwwiz to start the Hardware Installation Wizard

     

    When the Wizard has started, click Next

     

    Select 'Install the hardware that I manually select from a list (Advanced)', click Next

     

    Select 'Network adapters', click Next

     

    Select 'Microsoft' & 'Microsoft Loopback Adapter', click Next

     

    1. Right click network icon in the systray and click Network and Sharing Centre

     

    2. Click Change adapter settings

     

    3. Right-click the new loopback adapter and select Properties

     

    4. Un-check all items except Internet Protocol Version 4 (TCP/IPv4)

     

    5. Select Internet Protocol Version (TCP/IPv4), click Properties and configure the IP address to be the same as the Virtual Server (VIP), with a full subnet mask of the individual IP e.g. 255.255.255.255. Do not add a gateway.

     

    6. Click OK on the TCP/IP popup window, then click Close on the Local Area Connection window to save the new settings For Windows 2008, its not necessary to modify the interface metric on the advanced tab and should be left set to Automatic

     

    8. Rename the loopback "Loopback" from localareaconnection 2

     

    9. Run the following in a command prompt:

     

    netsh interface ipv4 set interface "Local Area Connection" weakhostreceive=enabled

     

    netsh interface ipv4 set interface "Loopback" weakhostreceive=enabled

     

    netsh interface ipv4 set interface "Loopback" weakhostsend=enabled

     

    10. Now repeat the above process for all other Windows 2008 real servers
