Note: I am not using the standard released firmware (Build 150xxxx) because address reservations do not work at all. Tp-link support has an internal release that does the job (this one). However, if SNAFUS force you to reset the device and you reload your settings, THE ADDRESS RESERVATION TABLE IS NOT RESTORED. Come on, Tp-link people. This is multi-decade old routing technology. What's the problem?
