MAC Address Generation Prevention

I have been told by Verizon and Activision that their routers do not have the ability to filter MAC addresses that are wired.
Verizion's competitor, Comcast, purchased a company for over $50 Million that does. This company is located in Silicon Valley.
It is simple for Activision to write code that filters/allows certain pre-determined MAC addresses. Why they don't have this feature throughout their routers is unfortunate.

IMO, unless the router was locked into a box with no key, MAC address filtering on wired would be pointless. 10 seconds of physical access is all that is needed to undo the MAC filtering.

Many warnings : prevented from using mac address because it is pinned to port

Hi
I am seeing my system log flooded (several per second) with event 28 warnings such as :
Port 'SWITCHPORT-SM-DB9DCFC7-E98D-438C-8998-CC0D9C14ED2B-1-1' was prevented from using MAC address '00-15-5D-00-B2-05' because it is pinned to port 'A0724966-695B-4552-B'.
Source : VMSMP
The environment is 2 X hyper-v 2008 r2 hosts. both have 4 NICs, 3 nics are connected to virtual switches and management OS is not allowed to share the network adapter, and then 1 NIC is obviously used by the host/mgmt OS and no virtual switch connected to
it. I am seeing the warnings on both hosts.
No load balancing or NIC teaming.
All VM's have their MAC addresses assigned dynamically and I cannot see any conflicting MAC addresses.
The warnings are logged for all or most of the MAC addresses and alternate between different "SWITCHPORT-SM-etc,etc" names.
Performance doesn't seem to be degraded, I've run continuous pings for more than an hour with no packet loss, just a single packet spike every now and then. Network access seems fine, Backup Exec 2012 jobs are succeeding, albeit somewhat slower than what
it was.
I don't know when it started, since these warnings have flooded out all else.
At first I thought it had something to do with a VM that I moved from one host to the other, where I copied the VHD accross and then created a new VM and assigned the original IP address to the new virtual NIC in the new VM. I then uninstalled the old hidden
NIC and restarted the VM in question, but that didn't stop the warnings.
Any ideas what could be causing this, or any tips on where I should start looking to isolate the cause ?

Got it fixed by creating new virtual switches, moving all VMs over to them, and afterwards deleting all the old virtual switches.
Still no idea what the cause could have been. How bizarre...

Does the ethernet adapter have a MAC address?

Hi, I wonder if anyone can answer this one for me. I use programs under bootcamp that need a 'dongle' to prevent them being used on more than one machine at once. ProE for example uses a Pluscom ethernet adaptor that carries its own unique MAC address that the license is assigned to. My question is, is the Mac ethernet adapter the same? does it have a unique address - should be six pairs of numbers / letters.
Just wondering if I could use one of the Mac adapters for this purpose.
Thanks for any help

Yes, the Apple Ethernet adapter will have a Media Access Control (MAC) address. In general, every network adapter (NIC) will have a unique MAC address. So if your program only works with a specifc MAC address, basically you can't install the program on a different computer without contacting the software vendor for a new installation code or whatever. (More specifically, you can't change the NIC. If you change computers, you need to keep the NIC.)
In Windows, to get the MAC address, open a command prompt and type "IPCONFIG /ALL" (without the quotes.) The line that says "Physical Address" is the MAC address. Note that you may have more than one NIC. (Wired, Wi-Fi, etc.) So you need to be sure you get the appropriate MAC address for the desired NIC.

I have a Linksys WRT54G wireless router that has a MAC address

A month ago, I could print from my PC and my Mac to my Epson printer over my Linksys WRT54G wireless network. Now, for some reason, I cannot connect and print from either computer. An Epson tech asked me to check the MAC address of the Mac and the printer to see if they were the same. They were not. He then opined that might be why I couldn't print.
I don't know what changed a month or so ago or why it changed. I have not done anything to change the MAC address on either the MAC or the printer.
The Epson guy said the problem might be fixed by adding my printer's MAC address to my router's MAC address. Something about "enabling MAC address filtering". Then he told me that was an issue to pursue with my router manufacturer. Naturally.
Speaking of that problem...someone else had it, too...another technician at another site wrote: "...by default, routers don't come with mac address filtering enabled...and if that's the case....then adding the printer's MAC will not solve any issue that you may be having..."
So, three qustions:
(1) Can I add my Epson Workforce 545 printer's MAC address to my Linksys router? Is that possible?
(2) If I can do it, how do I do it? I saw no "add" or "edit" functions on the Linksys WRT54G Status Page.
(3) What causes MAC address mismatching to happen? What is unstable in that assembly?
Solved!

Mac addresses with different devices will differ. No two devices will have the same mac address. this is also called the hardware address. This is designed so that it will serve as a unique identifier of your devices in the network which you can check thru the router. Now it is possible that wireless mac filter might be blocking it from connecting to the network. But it would be best to check as well and make sure that the printer is connected to your network and has the same ip address segment as your router.
How to check if mac filter is enabled:

MAC address management

Does anyone have more information on how Sun is generating MAC adresses for guest/IO/service domains and is their concern that this method will potentilly create duplicates in the enterprise.
I have seen where there is a range of MAC addrs Sun has set aside for manual assignment to LDOMs, however that does not solve the issue of managing MAC addresses across potentially thousands of LDOMs to prevent duplicates?

I'll have to look again, but I believe there is a calculation that is explained in the admin guide or in the Blueprints doc. Obviously this means there is the potential of MAC address collision. You can manually edit the MAC address, which is also in one of the docs I mentioned.

DHCP Server with the strange MAC address at the same time. This MAC address is HEX IP address!

Server version: Windows server 2008 R2 Ent.
Structure of DHCP scopes: Two DHCP server 50% to 50% all allocation for per scopes.
Question: Sometimes the DHCP server
allocate the IP address at the same time to the a strange MAC address per IP address, the type is "DHCP/BOOT", it cause DHCP scopes out of space at some time point. We need clear up them manually.
I found strange MAC address in HEX is the IP address which the server allocated.
Someone meet the issues before, any solution for this ?
Thanks !

WRT610N - Reserving a specific IP address for a given MAC address

This is the first router that doesn't allow this. I have to set up a computer to get an address using DHCP then I need to use that IP address and related info to set up a static IP address. That's just plain dumb. Then if I take a laptop to another location, I have to fiddle with setting up for DHCP again. Then When I come home, I have to reset all the settings on the laptop to do the static IP thing. If you move the computer around a lot, that's a lot of unnecessary fiddling.
Why not just have the router keep a table of MAC address and the IP address assigned for those computers. It would be a lot easier to configure the router once than reconfigure a compter a whole bunch of time. It's not rocket science or brain surgery. A lot of other routers do this and allow the user to set up reserved addresses

You may have stumbled over a known bug!
What you want to do is click on [DHCP Reservation] on the Basic Setup page and assign the Ip address based on the MAC of the connecting device.
But there is a bug! The JavaScript code generated in DHCP_Static.asp puts an extra space in a few Array definitions which result your browser not properly rendering the HTML code. So you get a window that is intended to allow you to manage the Ip assignment based on MAC, but the page is BROKEN.
(Right click on the page a select "View Source" from the context menu and you'll see something like this.)
===================================
| (Note: angle brackets replace with square brackets to prevent errors in the forum post.)
| [script language="JavaScript"]
| document.title = adbutton.dhcpres;
| var statics_table = new Array(
| 'Dummy1','00:01:02:03:AA:FF','101'
| ,'Computer2','00:55:FF:ED:04:99','102'
| ,'Roku','00:0E:44:55:66:77','110'
|
| );
===================================
I believe that blank line between the last entry and the final ");" is causing the problem. At least in every browser I've tried, a JavaScript error is generated at that point with: Message: Expected ')'
My guess is the router work fine. But since your only way to communicate with the router is via a web page that is broken, you can't make the changes you want to make!
I was told by Tech Support that they know of this issue and are working on a fix. I was also told....
:: Since the problem you have is regarding the DHCP Reservation, we will escalate
:: this case to the Case Management Team Irvine.
and...
:: We will escalate this concern to the Headquarter and a Senior Technician would contact you within 48 hours.
We'll see... I'm not holding my breath.

How to find MAC address on Apple TV (newest one)?

I'm trying to find the MAC address on my apple tv 3rd Generation. Any ideas? I've gone through the settings on it but can't seem to find it. It's up-to-date but no luck. Thanks!

Under settings in the network config options menu.

Mac address filter

Is it possible to identify the visitors mac address using PHP
if yes is there anything to prevent you from limiting access to specific mac addresses (say by using an IF statement to redirect other users to a different site)

You can identify the IP address, but that doesn't take you down to the level of the individual machine.

Block internet access by MAC address all the time

I want to be able to block MAC addresses from accessing the internet but allow them to use the network.
I can do this in other router interfaces but the BT Home Hub 2.0 has a VERY un user friendly interface and will not allow advanced internet access or other settings to be modifyed to suit my needs.
I am at an intermediate level at understanding network equipment and an expert at residential networking.

Not sure about the home hub 2, but on the home hub 1 you can use a "user defined" firewall setting to block access to a computer by specifying its IP address.
Source LAN
Interface 192.168.1.xxx (address you wish to block)
Destination WAN
Service ANY
Action Deny
You can tell the home hub to always use this IP address for the device you are trying to block.
There is probably a similar setting on the home hub 2.
By default I block all Internet access for devices, then I have rules to allow HTTP, HTTPS, POP3 and a couple of others.
I also have UpnP disabled.
This prevents any computer on the network accessing any non-standard ports.
There are some useful help pages here, for BT Broadband customers only, on my personal website.

Mac Address Filtering Issue with DI-624 router and HP D110 Wireless Printer

Just got the D110 Wireless Printer and cannot connect to the wireless router.
I have a D-Link DI-624 Air Plus Xtreme G 2.4GHz Wireless Router.
The error message that I'm recieving from the printer is that "Mac address filtering may be enabled on your wireless router. This can prevent your HP printer from connecting to your wireless network during setup....etc."
The D-Link is setup using WPA-PSK security. If I turn off all security than the wireless printer is able to connect. With WPA-PSK or even WEP enabled I cannot connect the printer to the wireless router. There is no connection to hardwire the printer and the router.
I've logged on to the router's admin and have confirmed several times that Mac filtering is turned off by going to Advanced > Filters > Mac Filters > and choosing Disabled Mac Filters. Where else is this setting? Why is the printer not able to connect?
Further, I check the logs on the router and it shows "Wireless PC Connected" and "Authentication Success" with a note that has the Mac Hardware Address matching the printer's mac hardware address on the Wireless Network Test Report. It would appear that the router is letting the Print in but that the printer is not able to communicate for some reason. It even shows under status > wireless that the printer is connected.
When i spoke to HP, they said to contact the router company and that they could not help. When I called D-Link they said tech support is no longer available for the model. I'm stuck, can anybody help?
This question was solved.
View Solution.

Windows XP, tried both the front of the printer as well as connecting via USB and using the software.
After a few hours on the phone with both D-Link and HP, the issue has been resolved.
Apparently eventhough Mac Filtering was disabled (set to Disabled MAC Filters), the Mac address had to be entered into the router to allow it while keeping the setting to Disabled Mac Filters. To me it appeared counter intuitive to enter the Mac address while it's set to Disabled Mac Filters so I did not try that before getting on the phone with HP. Further on this, the problem did not go away right after adding the mac address but rather after restarting the router as the mac address addition did not take effect without a reboot of the device.
HP was much more helpful than D-Link on this one though it would be nice for HP to add to their instructions and Wireless Network Test Report to add the Mac address just in case. I would have tried that step if it was stated that it's okay to add the mac address and keep mac filters disabled.

Enable mac address filtering vs. Access restriction

What is the difference between enabling MAC address filtering and access restriction on my wireless router? I am curious if one is better than the other. Do they do the same thing?

"MAC address filtering" will permit (or deny) a computer to login to your wireless network, based on it's MAC address. For example, a person would input the MAC addresses of the three wireless computers they own, and permit only these three computers to access their wireless network. This setting would therefore prevent computers with other MAC addresses from connecting to your wireless network. This setting effects only wireless connections.
"Access restriction" is primarily used to restrict or deny Internet access to a computer that is already connected to your network. For example, you might want to permit your son's game computer to access the Internet only on Saturday and Sunday. This setting can effect both wired and wireless connections.
Be aware that either of these settings can be circumvented by those who are computer saavy. For example, a MAC address can be faked. So an intruder could gain access to your network this way, or your child could bypass the restrictions you placed on him.
If you want to keep intruders from accessing your wireless network, rather than using MAC address filtering, you should use WPA, or preferably WPA2 encryption, and a strong password.

Chaning Apple ID for iTunes to .Mac address

I have an iTunes account that I created back in 2003 when I got my 3rd Generation iPod, and since then the whole family has used the account. It is at my AOL e-mail address, but I'm trying to completely get rid of that e-mail address because I rarely use AOL anymore. In iTunes, it lets you change your e-mail address, but if I try to change it to my .Mac address, it states that I cannot change a current account to a .Mac e-mail address, but instead I can sign in with the .Mac e-mail address instead as its own account. Is there any way I can either get around this obstacle or transfer all of my purchased music to a new account, so I don't have to worry about two accounts in the future, (i.e. what computers are authorized with what account; having to authorize twice for music purchased from today on with my .Mac address)? Thanks a bunch for any help!

Deny Mac address cannot use client ip address

Dear Team
How I can restrict Mac address in the denied list ,cannot use ip address.
Regards
Njsingh

Hi,
If you want to filter DHCP client by MAC address in order to prevent some device from obtaining IP address. You may enable Deny Filters on DHCP console first, and then New Filter by MAC address. Detailed steps you may reference the link below:
http://technet.microsoft.com/en-us/library/dd759190.aspx
Windows Server 2008 R2 or above system version has this function. Reference:

please help me

I doubt it. You should have written it down as a preventative measure if thst is what is required by quick heal.
Quick Heal isi nternet security software. It does not appear to have anything to do with theft location.
