-===== Add wireless MAC to allow access list =====
+===== Add wireless MAC =====
+The following scriptlet allows to add a MAC address of a wireless device to the access allow list of a //Medion MD 90400 Wireless Lan Set// (A DSL router and wireless LAN switch sold in Germany) bypassing the stupid javascript checks of the input data. (In my case, the native web interface didn't allow a MAC address to start with an odd number)
   password=<router password>

+===== Reserve IP for specific MAC =====
+Same problem arises when setting a dedicated constant IP number to a device. Same solution applies:
+  password=<router password>
+  ip=<ip number to reserve>

+This scriptlet allows you to get your public IP when using a //MD 90400 Wireless Lan Set// for DSL uplink:
