OVPN still uses 4G even when WIFI is connected

Post by -Mike- » Tue Sep 10, 2019 8:10 pm

Hi there,


i got a Problem since i use OVPN. I am no expert, but i managed to configure it on my Synology NAS, my FritzBox, a dynDNS Service, the app and automate it with tasker.

So for me it was hard work of learning, but now it does exactly and perfectly what i want it to do.


Unfortunately i now see the Problem, that when i am connected to 4G and my phone connects to WIFI, all data is still sent over 4G. Just today it drained all my data when watching Videos while being connected to WIFI.....
Also if the Connection in a Basement is so bad that i only get a 2G Signal, the link stays connected but the Internet is unusable, while the phone is connected to a perfect WIFI Signal.


I use Android 9 (Huawei EMUI 9.1) and OVPN 3.0.7.


I only found this threads, which Arent helpful for me.

Thanks for help!

The detailed testing steps are as follow:

Pre-requisite:
a) OpenVPN server or client profile will route all traffic via VPN server: push "redirect-gateway" or redirect-gateway in client
b) OpenVPN Connect in Phone will reconnect itself
c) A wifi network with large speed difference with your iPhone
i) either a very slow one (ADSL connection)
ii) or a very fast one (Optic Fiber one which goes over 100Mbps and a fast router)

Testing steps:
1) Connect Phone to WiFi
2) Connect Phone to OpenVPN server
3) Do the speed test (take note that it is the WiFi speed)
4) Open Settings app, switch off WiFi
5) Switch on WiFi, connect back to the same WiFi network
6) Wait for VPN auto-connect itself
7) Do the speed test again (take note that it is not the WiFi speed this time, it is your cellular data speed!)
