+===== What is NAT? =====
+NAT is a technology which alters the devices' addresses to connect them to the FeM-Net with only a single IP address.
+For this to work, so-called “local” IP-addresses are usesd “behind” the router which aren't used in the internet.
+A further effect is that connections cannot be established from the internet to the devices which are connected to the router.
+NAT violates §9 of our terms of use and must not be used in the FeM-Net.
+===== How can I disable NAT? =====
+Consumer routers usually do not have a separate option to disable NAT.
+However, normally there are operation modes which enable further settings and suffice to disable NAT and provide a flawless operation in the FeM-Net.
+In the below sections we describe how to switch to such an operation mode for some common router manufacturers.
+==== TP-Link ====
+TP-Link provides a setting called “Access Point”.
+It disables NAT, the firewall, DHCP and thus makes the device compliant to the FeM-Net rules.
+TP-Link provides several manual on their website:
+  * https://www.tp-link.com/de/support/faq/2066/
+  * https://www.tp-link.com/us/support/faq/1384/
+==== AVM FritzBox ====
+Systems of AVM have a mode called “IP client”.
+It disables NAT, the firewall, DHCP and thus makes the device compliant to the FeM-Net rules.
+Activation of "IP client" mode:
+  * Log in to the interface of your FritzBox (e.g. via ''http://fritz.box'' or ''http://192.168.178.1'')
+  * Navigate to "Home Network" > "Network" > "Network Settings" (perhaps you have to activate the "Advanced View")
+  * Choose "IP client" as operating mode
+  * Choose if your router is connected via WiFi or LAN cable with FeM-Net. //Caution! This is not about how your devices connect to the router!// You have two options:
+      * The FritzBox is connected via cable with your network socket (recommended).
+          * Enable the option "via LAN" for your home network access.
+          * Connect the network cable to "LAN 1" on the FritzBox and to your network socket in your room.
+      * The FritzBox should be connected with FeM-Net via FeM-WiFi (not recommended).
+          * Enable the option "via Wi-Fi" //(might also be called "via WLAN"?)// for your home network access.
+          * Under "Select Wi-Fi Network" //(might be called differently, e.g. "Radio Network")//, select one of the FeM-WiFi networks (e.g. "FeM.PSK" or "FeM.1X") and enter your login data.
+  * Click on "Apply". Now, the FritzBox interface is no longer available at ''http://fritz.box'', but under the IP address that was assigned to your FritzBox. You can check this address on the [[https://myinfo.fem.tu-ilmenau.de|MyInfo page]].
+<WRAP half info centeralign>
+The English option names were taken from the [[https://en.avm.de/service/knowledge-base/dok/FRITZ-Box-7590/3244_Setting-up-the-FRITZ-Box-as-an-IP-client/|AVM manual page]] (last accessed on 2021-08-03), which does not describe the case for Wi-Fi connection. If you find any wrong labels, please let us know via <helpdesk@fem.tu-ilmenau.de> so we can improve this wiki page.

+==== AVM FritzRepeater ====
+The FritzRepeater isn't able to do NAT and thus doesn't require any special configuration to be compliant to the FeM-Net rules.
+However, it is probably wanted to connect the FritzRepeater to the FeM-Net via cable instead of WiFi.
+For this, the repeater needs to be configured accordingly.

+//Hint: In AVM's manuals whenever “FritzBox” is stated, it means the router and in case of the FeM-Net just the connection to the rest of the FeM-Net.//
