The ‘MAC Address Changer’ allows you to select a network adapter and modify its MAC, either with a user-defined or a random one; this can be reverted with a single button press. SMAC is a powerful, yet easy to use MAC Address Changer (Spoofer) for Windows 7, XP, 2003, VISTA, 2008 systems, regardless of whether the manufacturers allow this option or not. The new MAC addresses you change will sustain from reboots. Technitium MAC Address Changer (TMAC) is a popular freeware utility to change or spoof MAC address of wired or wi-fi network adapters for Windows. Apart from changing MAC address, you can use the feature rich software to completely configure your network adapter and also has presets feature to allow quick switching between multiple network.
MAC address filtering allows you to block traffic coming from certain known machines or devices. The router uses the MAC address of a computer or device on the network to identify it and block or permit the access. Traffic coming in from a specified MAC address will be filtered depending upon the policy.
Mac Address Filtering Disable
To enable MAC address filtering:
Mac Address Filtering With Spectrum
- Choose Firewall > Advanced Settings > MAC Filtering.

- Block and Allow the Rest—Choose this option to block the traffic from the specified MAC addresses and to allow traffic from all other addresses.

- Enter the MAC address and description to add to the table and click Save. Repeat for each address to allow or block.
- Click Save.
If you enable MAC filtering, in the Policy for MAC Addresses Listed Below field, choose one of the following options:
For example, two computers are on the LAN with MAC addresses of 00:01:02:03:04:05 (host1), and 00:01:02:03:04:11 (host2). If the host1 MAC address is added to the MAC filtering list and the “block and allow the rest” policy is chosen, when this computer tries to connect to a website, the router will not allow it to connect. However, host2 is able to connect because its MAC address is not in the list. If the policy is “allow and block the rest,” then host1 is able to connect to a website, but host2 is blocked because its URL is not in the list. The MAC filtering policy does not override a firewall rule that directs incoming traffic to a host.
