VPN continues to use 3G data connection after I connected to wifi.
Yesterday I think I discovered why my data usage has been so high... I live in China so I use VPN a lot to jump the Great Fire Wall.
This is my behavior and expectations around using VPN.
- I start up my VPN connection when I am using 3G network.After established connection the VPN icon appears in the statusbar.
Now I expect all my data traffic to pass thru VPN using 3G. (L2TP to VPN provider Astrill if that matters). - When I enter one of "my wifi-zones" (home or office) my iPhone automatically connects to the wifi. The 3G icon on the statusbar is replaced with the wifi icon, the VPN icon is still in the statusbar.Now I expect all my data traffic to pass thru VPN using my newly established wifi connection. Basically I expect the 3G data to switched off.
But.....
Yesterday when I got home my wife told me the Internet was down again (had some problem lately with our provider). I checked the router and yes the WAN address was set to 0.0.0.0. We did some basic troublefighting as restarting the router and the ADSL modem - and tried again. My wife said nope - no change, wifi connection is ok but no Internet/WAN connection.
After I while I bring out my iPhone to try and notice the wifi symbol indicating wifi and then VPN icon still there. I try to use Safari and I can access Internet content and continue to send/receive Google Hangout messages. Tell my wife Internet is back....she tries as well without success. I check the router, WAN address still 0.0.0.0.
This leads me to suspect that the 3G data connection is not switched off when I connect to wifi (which is my expectations as the 3G icon disappears) - and VPN is not re-established/switched to use wifi. Instead the VPN continues to use 3G data connection without telling me that...
Anyone else experience this?
To me it sounds like a bug...one that costs me money which makes it serious.
I am on iPhone 5, IOS 8.1
