MAC addresses

Many devices don’t have enough unique MAC addresses assigned by the vendor (in batman-adv, each mesh interface needs an own MAC address that must be unique mesh-wide).

Gluon tries to solve this issue by using a hash of the primary MAC address as a 45 bit MAC address prefix. The resulting 8 addresses are used as follows:

  • 0: client0; WAN
  • 1: mesh0
  • 2: ibss0
  • 3: wan_radio0 (private WLAN); batman-adv primary address
  • 4: client1; LAN
  • 5: mesh1
  • 6: ibss1
  • 7: wan_radio1 (private WLAN); mesh VPN
