 For the firewall nodes, configure `mgmt0` and `lo` as usual for L3 devices. Additionally, the firewall nodes should define the following interfaces:
 
-    { "name": "lan0", "mac_address": "12:34:56:ab:cd:e0" },
-    { "name": "lan1", "mac_address": "12:34:56:ab:cd:e1" },

+    { "name": "lan1" },
     { "name": "mgmt1", "ip_addresses": [{ "address": "fe80::1/64" }] },
 
 The MAC address should be defined for each interface, as they are renamed by the OS. The `mgmt1` interface is used for synchronizing connection-tracking information and should use the `fe80::1/64` and `fe80::2/64` addresses for the first and second firewall node, respectively.
