 The MAC Address menu has settings to let you electronically change (or "spoof") the MAC (Media Access Control) Address of various network interfaces. Note that this function does **not** change the factory-assigned MAC Address in the device's chip. It just overlays the different address in software. The MAC Address menu has settings to let you electronically change (or "spoof") the MAC (Media Access Control) Address of various network interfaces.

-A MAC address is called a Universally Administered Address (UAA) when it's set by the manufacturer or a locally-administered addresses (LAA) when it is assigned by a System Administrator. The first three octets (group of eight bits) are the Organizationally Unique Identifier (OUI). The OUI is a 24-bit number that identifies the manufacturer, organization, or vendor. The last three pairs of digits are the number specific to the device, which is known as Network Interface Controller (NIC) specific portion of the address.+A MAC address is called a Universally Administered Address (UAA) when it's set by the manufacturer or a locally-administered addresses (LAA) when it is assigned by a System Administrator.

 FreshTomato sets wanX MAC Addresses as follows: FreshTomato sets wanX MAC Addresses as follows:
  
-  *  WAN  => eth0 MAC +16  (decimal value(in releases 2021.and older: eth0 = MAC + 1 (decimal value)) +  *  WAN  => eth0 MAC + (decimal) 16  [in releases 2021.and older: eth0 = MAC + 1 (decimal value)] 
-  * WAN2 => eth0 MAC +17 (decimal value+  * WAN2 => eth0 MAC + (decimal) 17 
-  * WAN3 => eth0 MAC +18 (decimal value+  * WAN3 => eth0 MAC + (decimal) 18 
-  * WAN4 => eth0 MAC +19 (decimal value)+  * WAN4 => eth0 MAC + (decimal) 19
  
-For example, on a router with LAN hardware MAC Address of 2C:30:33:DB:F7:CC, FreshTomato would now set the WAN MAC Address to 2C:30:33:DB:F7:DC, (by adding CC + 16). On releases 2021.7 and older, FreshTomato would have configured the default WAN MAC Address as 2C:30:33:DB:F7:DD (by adding DC + 1).+For example, on a router with LAN hardware MAC Address of 2C:30:33:DB:F7:CC, FreshTomato would now set the WAN MAC Address to 2C:30:33:DB:F7:DC, (by adding CC + 16).

 +===== MAC Address Notes =====
 +
 +Until at least release 2021.8, FreshTomato has a problem caused by changing the wireless MAC Address.
 +
 +Changing the first 3 octets of the MAC Address can cause some issues such as wireless interfaces to drop. For details, please see: \\ [[https://bitbucket.org/pedro311/freshtomato-arm/issues/173/wl11-drops-and-upon-restart-attempt-all]]
