The new DHCP console makes it easier to add MAC addresses to your filter list by using your existing leases. You could add new filtering lists by entering the MAC addresses of all the machines on your network in an Excel spreadsheet and then entering each of these, one at a time, in the DHCP console. Generate reservations and link layer address filtering lists from current leases So, before you start your MAC address filtering, make sure to read the next section, which will make entering MAC addresses in your allow list a lot easier.

Note the warning here: clients that had previously received IP addresses will be denied address renewal, unless their MAC addresses/patterns are present in the allow list. Put checkmarks in the Enable Allow List and/or Enable Deny List depending on what you want to do. Then in the IPv4 Properties dialog box, click the Filters tab. Right click IPv4 in the left pane of the console and click Properties. However, there is one more thing you need to do. You’d think that after you click Enable it will enable MAC address filtering for your allow and deny lists. When you select the Filter option, you will see the New Filter dialog box, where you enter a MAC address and an optional Description. You can see an example of this in the figure below. In general, you should have your list of MAC addresses that you want to allow or deny first, then create the filter entries, and then enable the allow or deny options. You have two options when you right click the Allow or Deny node – New Filter and Enable. You can access this feature by opening the DHCP console and navigating down to the Filters node in the IPv4 tree (note that filters are not available for IPv6 addresses). We’re used to creating such lists on small wireless networks, but why not do the same thing on both your wired and wireless networks? You can make it easier to exert some control over who connects to your network by configuring your MAC address allow and deny lists in your DHCP server.

In Windows Server 2008 R2 you can now create “allow” and “deny” filter lists for MAC addresses in DHCP. Create new DHCP options that apply only to reservations.Create reservations from current leases.Generate link layer address filtering lists from current leases.MAC addressing filtering for DHCP leases.The new DHCP features that you’ll find in Windows Server 2008 R2 include: It just works and rarely do you hear any complaints about addressing issues.īut now, with Windows Server 2008 R2, there’s something new on the DHCP front, and in this article, I’ll tell you about these cool new features. You back up the databases and restore them when you need to. You design and then plan your DHCP network infrastructure, and then you deploy it. However, that was over 20 years ago and the excitement about DHCP has faded quite a bit in the interim. It was clear that DHCP was here to stay and would be a constant companion in our networking lives.

What a wonderful discovery that was by using DHCP we could assign IP addresses, subnet masks, domain names, default gateway and even more by using DHCP options. But then we discovered the conveniences of DHCP and how DHCP can automatically assign IP addresses to the computers on the network. When we were just starting out with TCP/IP, many of us manually assigned addresses on our small networks. And addressing? We didn’t need to worry about addressing at all with NetBEUI but now with TCP/IP addressing was everything. The whole name resolution process changed, in that now we needed to think about using DNS for name resolution on our networks. With TCP/IP, we saw big improvements in network performance because not everyone was on the same Ethernet broadcast domain we could now have routed networks. Then along came the Internet and with it, the TCP/IP protocol. Of course, being a broadcast based name resolution protocol that wasn’t routable meant there was a healthy amount of traffic on your single broadcast domain. On NetBEUI networks, all you needed to do was name the computers whatever names you wanted, making sure that you didn’t duplicate names, and you were good. However, it wasn’t really all that long ago when many of us were running local NetBEUI networks, where addressing wasn’t even an issue.
