This script generates a random MAC address for the WAN interface on an OpenWRT/LEDE router. It is implemented as an init script, so it is able to randomize the MAC address every time the router restarts.

Nothing special. It should work on a base OpenWRT/LEDE system.

1. Copy wan-mac to /etc/init.d/
2. Make sure the file is executable (chmod +x /etc/init.d/wan-mac)
3. Modify the START line in the file if you'd like to customize the init order (optional)
4. Enable the service so it will randomize the MAC address on every boot (/etc/init.d/wan-mac enable)
5. Restart your router or start the service manually (/etc/init.d/wan-mac start)

Tested on:

• TP-Link TL-WR1043ND 1.0 running OpenWRT Chaos Calmer
• TP-Link Archer C2600 (AC2600) running LEDE snapshot
