+Simple software for creating a L2 connection over a TCP socket, written in python.
+It's still in alpha stage, please report any bugs.
+Later the project gonna be rewritten in C.
+
+# Dependencies
+
+The only dependencie is pytun library, you can install it using the command below
+
+```bash
+ $ pip install python-pytun
+```
+ 
+# Using
+
+First you need a server, in order to run it just type
+
+```bash
+ $ python3 server.py
+```
+
+It will start the server, by default it listens at 127.0.0.1:9999, to change that, just open server.py in a text editor and change ADDRESS = "127.0.0.1" and PORT = 9999 to the address:port you need, for example your local ip address.
+Also you can change the name of the interface, ip, netmask, logging level, MTU and disable/enable auto configuring of the NIC, just read the comments in the "Defining global variables" section if you want to know how to do that.
+
+When the server is started, you should see a TAP network interface.
+
+
+When you have a server, you can connect to it via the client, to do that just edit client.py and change ADDRESS and PORT to the address and port of your server.
+To start the client just type
+
+```bash
+ $ python3 client.py
+```
+
+When client is started you should see a new TAP network interface.
+
+When a client connected to the server, you can access the server from a client via L2, for exaple you could ping the server, or route your traffic through it.
+Warning, any client can access the server, but a client can't access another client, it made that way to use the app as a public VPN-like service.
