+===== Connecting a Client =====
+  * Everything is now set up and ready for the first client to connect.
+  * We will use OpenWrt with the following ///etc/config/network// config.
+  * The PPPoE username is ''dirk'' and  password is ''testing123''.
+<code bash>
+config interface 'loopback'
+        option device 'lo'

+  * This device has to be connected to the **same network** (broadcast domain) where our Accel-ppp server is running in order for the network packets to reach the PPPoE server.
+===== Checking The Log File =====
