Post subject: | DNS issue with Android Lollipop |
Hi, since I made an upgrade to lollipop I have a DNS issue. If I sign in with NeoRouter VPN free my mobile android device get no DNS answers any more. I can ping the DNS IP and any other IP but my device seems to be unable to resolve hostnames - e.g. if I sign in and try to open the "Help" page directly from the NeoRouter App, my browser returns with "page unavailable". If I sign out and open the "Help" page again my browser displays the page as expected. I tried several other DNS severs but without success. As soon as I sign out DNS works as expected. Any help with this issue is apprecated. Thanks Jon |

Hi KevinZ, the device is a note 4, N910F with Android 5.0.1, SimplRom (http://forum.xda-developers.com/note-4/snapdragon-dev/rom-simplrom-v1-t3004628). Yesterday I tried another kernel without success. Have a nice day. jon |

Hi, I just tested NeoRouter free with the stock Android Lollipo 5.0.1 (N910FOXA1BOB4_DBT) on a Samsung N910F. As soon as I sign in with NeoRouter DNS requests fail. Any help is appreciated. Jon |

Hi jon, I cannot reproduce your issue on Nexus 9 (Lollipop). But I don't have a Samsung N910F. NeoRouter doesn't change DNS settings, so I'm thinking the ROM may change something when VPN is up. Can you try to add DNS entry (8.8.8.8) to your phone after NR is up? If you can hook up adb catlog to your phone, you can collect the detailed information when NR starts. Generally it shows the default DNS entry (8.8.8.8). Thanks, Kevin |

Hi Kevin, Past weekend I manually set the DNS server to 8.8.8.8 after I signed in with NeoRouuter - unfortunately without success. I rarely used adb in the past but I remember I set it up some time ago - so if you could send me the adb command line(s) to capture NR I will happily use it to provide you with debugging information. Attached you will find two logcats I made with Logcat Extreme: 1) NeoRouter per app capture during NR session 2) capture of ConnectivityService during NeoRouter session I hope the attached debugging information is useful. Cheers jon

Hi Kevin, can I further support you in any way to nail down and solve this issue? I like NeoRouter very much and I would like to use it on Samsung TouchWiz Lollipop. Thank you |

Hi Jon, Thanks for your log file. However it seems ok. Can you try to get the routing table and dns settings before running NR client and after sign in to NR client. You may need to connect your device to a computer, and run adb shell show Android routing table: # cat /proc/net/route or # ip route show show DNS server: # getprop net.dns1 # getprop net.dns2 Thanks, KevinZ - NeoRouter team |

Hi Kevin, before running NR client: Code: ip route show 172.16.254.0/24 dev wlan0 proto kernel scope link src 172.16.254.21 getprop net.dns1 8.8.8.8 getprop net.dns2 8.8.4.4 after sign in to NR client Code: ip route show 10.254.0.0/24 dev tun0 proto kernel scope link src 10.254.0.3 172.16.254.0/24 dev wlan0 proto kernel scope link src 172.16.254.21 getprop net.dns1 8.8.8.8 getprop net.dns2 8.8.4.4 Cheers jon |
