 # Port Mapping
 In order to allow clients from the external network to connect to server port on the internal network, ports have to be mapped. An external port is mapped to an internal port of a specific internal IP address. Use the "portmap add" command for that. Port mappings can be listed with the "show" command and are saved with the current config. 
 
-However, to make sure that the expected device is listening at a certain IP address, it has to be ensured the this devices has the same IP address once it or the ESP is rebooted. To achive this, either fixed IP adresses can be configured in the devices or the ESP has to remember its DHCP leases. This can be achived with the "save dhcp" command. It saves the current state and all DHCP leases, so that they will be restored after reboot. DHCP leases can be listed with the "show stats" command.

 # Automesh Mode
 Sometimes you might want to use several esp_wifi_repeaters in a row or a mesh to cover a larger distance or area. Generally, this can be done without any problems with NAT routers, actually you will have several layers of NAT. Of course, the available bandwidth goes down the more hops you need. But users have reported that even 5 esp_wifi_repeaters in a row work quite well.

 By setting upstream_kbps and downstream_kbps to a value != 0 (0 is the default), you can limit the maximum bitrate of the ESP's AP. This value is a limit that applies to the traffic of all connected clients. Packets that would exeed the defined bitrate are dropped. The traffic shaper uses the "Token Bucket" algorithm with a bucket size of currently four times the bitrate per seconds, allowing for bursts, when there was no traffic before.
 
 # MQTT Support
-Since version 1.3 the router has a build-in MQTT client (thanks to Tuan PM for his library https://github.com/tuanpmt/esp_mqtt). This can help to integrate the router/repeater into the IoT. A home automation system can e.g. make decisions based on infos about the currently associated stations, it can switch on and of the repeaters (e.g. based on a time schedule), or it can simply be used to monitor the load. The router can be connected either to a local MQTT broker or to a publically available broker in the cloud. However, currently it does not support TLS encryption.

 By default the MQTT client is disabled. It can be enabled by setting the config parameter "mqtt_host" to a hostname different from "none". To configure MQTT you can set the following parameters:
 - set mqtt_host _IP_or_hostname_: IP or hostname of the MQTT broker ("none" disables the MQTT client)

 # Building and Flashing
 To build this binary you download and install the esp-open-sdk (https://github.com/pfalcon/esp-open-sdk). Make sure, you can compile and download the included "blinky" example.
