[Q] strange networking/routing/nameserver search problem? [Huawei P6] topic

Hello,

since a while, i have a very strange and frustrating network problem with my Huawei p6. The ROM is "Omni Rom", i think - but it shouldn't matter.

The problem is: when i try to connect through wlan (i have no mobile internet), according to the network manager of android, it should working. But i still can't acess internet services.

I had installed an firewall (think it was adwall), which i've deleted (with the rules, see below) but still i can't acces anything beyond my local device.

Unfortunately, i cant interpret the results below, because of my not-existent knowledge about networking/routing/whatever
