-====== Coova Chilli Standalone ======
+====== CoovaChilli Standalone and with Backend ======
+=== What is chilli ===
+Chilli is running on the NetModule router and has three major interfaces:
+  * A downlink interface for accepting connections from clients - typicaly the WiFi interface
+  * A radius interface for authenticating clients -> Radius server runs on the back end
+  * An uplink network interface for forwarding traffic to other networks -> VPN tunnel to back end
+=== What is the difference beween Standalone and Backend ===
+In a **Standalone** scenario all software runs on the NetModule router and beside the internet connection no other functionality is needed.
+In a **Backend** scenario there is additionaly functionality on an additional server. In a typical scenario the router is connected via bridged VPN (layer 2) to the backend server and all trafic is routed through the tunnel. The landing pages as well a radius server for user management are also running on the backend.

+#  form:
+#  	num[hdwm] where:

+	#
+	#  The server also looks up the IP address from DNS once, and

+	#  updated, the server WILL NOT see that update.
+	#
+	#  One client definition can be applied to an entire network.
+	#  e.g. 127/8 should be defined with "ipaddr = 127.0.0.0" and
+	#  "netmask = 8"
+	#
+	#  If not specified, the default netmask is 32 (i.e. /32)

+	#  We do NOT recommend using anything other than 32.  There

+	#  Using netmasks of other than 32 can cause security issues.

+	#  You can specify overlapping networks (127/8 and 127.0/16)
+	#  In that case, the smallest possible network will be used
+	#  as the "best match" for the client.
+	#
+	#  Clients can also be defined dynamically at run time, based

+	#  etc.
+	#  See raddb/sites-available/dynamic-clients for details.

+#   If the server builds and installs, but fails at execution time

+#   directive to work around the problem.
+#
+#   The cause is usually that a library has been installed on your

+#   executing as root (or another user), your personal environment MAY
+#   be set up to allow the dynamic linker to find the library.  When
+#   executing as a daemon, FreeRADIUS MAY NOT have the same

+#
+#   To work around the problem, find out which library contains that symbol,
+#   and add the directory containing that library to the end of 'libdir',
+#   with a colon separating the directory names.  NO spaces are allowed.
+#
+#   e.g. libdir = /usr/local/lib:/opt/package/lib
+#
+#   You can also try setting the LD_LIBRARY_PATH environment variable

+#  to that group, too.  Any other groups listed for the specified "user"
+#  in "/etc/group" are also added as part of this process.
+#
+#  The current working directory (chdir / cd) is left *outside* of the
+#  chroot until all of the modules have been initialized.  This allows
+#  the "raddb" directory to be left outside of the chroot.  Once the
+#  modules have been initialized, it does a "chdir" to ${logdir}.  This
+#  means that it should be impossible to break out of the chroot.
+#
+#  If you are worried about security issues related to this use of chdir,
+#  then simply ensure that the "raddb" directory is inside of the chroot,
+#  end be sure to do "cd raddb" BEFORE starting the server.
+#
+#  If the server is statically linked, then the only files that have
+#  to exist in the chroot are ${run_dir} and ${logdir}.  If you do the

+#  for the server to be able to read the shadow password file.  If you can
+#  authenticate users while in debug mode, but not in daemon mode, it may be
+#  that the debugging mode server is running as a user that can read the
+#  shadow info, and the user listed below can not.
+#

+#
+#  If this value is set too low, then duplicate requests from the NAS
+#  MAY NOT be detected, and will instead be handled as seperate requests.
+#
+#  If this value is set too high, then the server will cache too many

+#  If this number is too low, then when the server becomes busy,

+# THREAD POOL CONFIGURATION
+#
+#  The thread pool is a long-lived group of threads which

+#
+#  You probably want to have a few spare threads around,
+#  so that high-load situations can be handled immediately.  If you
+#  don't have any spare threads, then the request handling will
+#  be delayed while a new thread is created, and added to the pool.
+#
+#  You probably don't want too many spare threads around,

+#  not doing anything productive.

+	#  keep a runaway server from taking the system with it as it spirals

+	#
+	#  You may find that the server is regularly reaching the

+	#  'max_servers' doesn't seem to make much difference.
+	#
+	#  If this is the case, then the problem is MOST LIKELY that
+	#  your back-end databases are taking too long to respond, and
+	#  are preventing the server from responding in a timely manner.
+	#
+	#  The solution is NOT do keep increasing the 'max_servers'
+	#  value, but instead to fix the underlying cause of the

+	#  servers to handle transient load spikes.
+	#
+	#  It does this by periodically checking how many servers are
+	#  waiting for a request.  If there are fewer than
