+## Configuration
+
+### Interfaces
+
+The `/perm/interfaces.json` configuration file will be [automatically created](https://github.com/rtr7/tools/blob/57c2cdc3b629d2fbd13564ae37f6282f6ee8427f/cmd/rtr7-recovery-init/recoveryinit.go#L320) if it is not present when you run the first recovery.
+
+Example:
+
+```json
+{
+    "interfaces": [
+        {
+            "hardware_addr": "12:34:56:78:9a:b0",
+            "name": "lan0",
+            "addr": "192.168.0.1/24"

+            "name": "uplink0"
+        }

+
+### Port Forwarding
+
+The `/perm/portforwardings.json` configuration file can be created to define port forwarding rules.
+
+Example:
+
+```json
