(posted this in Shibby's thread, but it got lost quickly) TomatoUSB - Shibby v120 on Cisco E4200 How do I change the LAN MAC? I can change the WAN, WL0 and WL1, but not the LAN. I tried nvram with: nvram set et0macaddr=XX:XX:XX:XX:XX:XX nvram commit But it doesn't stick - either via a soft reboot, or a power cycle. Always reverts back to the "Default" setting. I have quite a few virtual machines running on several host servers. They are all configured for "Private" networking (Windows), which FYI is all tied to a LAN MAC address it designates as a "network" in Windows. When the "gatway" MAC changes, it forces all servers to a "public" firewall mode - effectively cutting off all remote access to the server (including RDP!). Needless to say, if the MAC address of the gateway changes, it's a PITA to go in and reset all the firewalls and networks for each and every VM and host and desktop. I've had to do it once or twice with the Verizon FiOS router and WRT54G swaps, etc. I was able to set the LAN MAC in Tomato. Thanks in advance!
