</div>The Android App does no narrowing itself, that happens on the responder<br>
only. To tunnel all traffic from the Android device, set<br>
leftsubnet=<a href="http://0.0.0.0/0" target="_blank">0.0.0.0/0</a> on the responder.<br></blockquote><div><br></div><div>So now my Android device proposes both TSi and TSr as <a href="http://0.0.0.0/0">0.0.0.0/0</a> and in the gateway I've configured leftsunet as <a href="http://0.0.0.0/0">0.0.0.0/0</a>.</div>
<div>Now when I establish the tunnel, typing "ip route show" in android device shows following:</div><div><br></div><div><div><a href="http://0.0.0.0/1">0.0.0.0/1</a> dev tun0 scope link </div><div>default via 10.10.11.1 dev wlan0 </div>
<div><a href="http://10.10.11.0/24">10.10.11.0/24</a> dev wlan0 proto kernel scope link src 10.10.11.5 </div><div>10.10.11.1 dev wlan0 scope link </div><div><a href="http://128.0.0.0/1">128.0.0.0/1</a> dev tun0 scope link</div>
</div><div><br></div><div>where 10.10.11.15 is the ip address of android device over the wlan0 interface and tun0 also gets same virtual Ip assigned by the gateway.</div><div><br></div><div>With this when I run tcpdum on both tun0 and wlan0, I see all the ESP packets going through Wlan0 and not tun0.</div>
<div><br></div><div>What am I missing here? Why is the route added as <a href="http://0.0.0.0/1">0.0.0.0/1</a>? My intention is to route all the traffic originating from my android device to the </div><div>gateway using the tun0 interface.</div>
