MAC Filter Import Tool

  • Article

Hello Everybody,

Thanks for all those who tried the MacFilterCallout dll. As you all must have checked out by now that Link Layer Filtering feature is a part of Windows Server 2008 R2 DHCP Server. DHCP Server team has come up with a GUI based tool which will let an administrator import the MAC addresses specified in MACList.txt file (used by MacFilterCallout dll), into the allow/deny list of Windows Server 2008 R2 DHCP Server.

This tool will work only on Windows Server 2008 R2 or above. DHCP Server role must be installed and the service must be up and running. Comments corresponding to each MAC address entry can be edited in place before you import the entries into the DHCP Server database.

    Can use this tool remotely from my Win7? This tool will have a Select DHCP server option?

    If you are using the inbox MAC address filtering feature which has been shipping inbox since Windows Server 2008 R2, you can do so using the DHCP PowerShell cmdlet Add-DhcpServerv4Filter with a -Force parameter. See technet.microsoft.com/.../jj590713.aspx For using DHCP PowerShell, you will need a Windows 8 client/server with RSAT installed. DHCP PowerShell in DHCP RSAT of Windows 8 works with DHCP server running on Windows Server 2008 and above.

    Great tool! Would be even nicer if it could import wild cards.

    Hi Keith, Could you please try importing this using the DHCP PowerShell cmdlets. See blogs.technet.com/.../dhcp-mac-address-filter-management-made-easy-with-dhcp-powershell.aspx You will need a Windows 8 client with RSAT installed to use DHCP PowerShell. This will work with DHCP Server on Windows Server 2008 R2 - I presume that's what you are using.

    Joey, if you have a Windows 8 client, please install RSAT (Remote Server Administration tool) and use the DHCP PowerShell cmdlets and PowerShell pipelining to perform export/import of MAC address filters. DHCP PowerShell cmdlets work with Windows Server 2008 R2.

    Where do I find info about this tool? Can I synchronize 3-4 different win2008 R2 DHCP MAC-databases using this tool. Or which API can I use to program the synchronize?

    Is there a way to overwrite an existing allow when importing deny MACs or vice versa?

    Hi There,I'm trying to export an allow list from one dhcp server and then go to another dhcp server on another subnet and import the list. But I get the following error: Error: File format not proper. Missing MAC_ACTION in beginning of file. This is how the file is set up:Allow,F0-CB-A1-4A-F2-4C,name.wmrsd.lanAllow,E8-39-35-4A-A8-22,LESRM37LABJ.wmrsd.lanAllow,E8-39-35-45-9F-F4,LESRM37LABE.wmrsd.lan

    @Merala, make sure you have MAC_ACTION = {ALLOW} spelled correctly, it seem to be case sensitive. I had to correct it for the import tool to work fine, although the feature was running smoothly.
