Lollipop routing workaround in 0.6.26 not effective #311

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
As discussed on G+, Lollipop requires a route to the connected network to be 
added.

Simply adding the local address is rejected.

The attached patch normalises the route added for the network to remove the 
host part of the address.

With this, the VPN connection is able to connect to the network address

Sorry, it's not fixed. I tested on beta version: 
http://plai.de/android/ics-openvpn-0.6.27pre.apk and problem still exists.

This issue is marked as fixed. But I tested your beta and it seems to be not 
fixed though. Am I testing wrong version?

I have tried the beta 0.6.27 and also have no routing.  I am getting the route 
added correctly for the VPN network (patch in #1), but it is rejecting the 
pushed routes.

report)

Indeed, it still is not working. Please take a look

I have re-installed 0.6.26 and confirmed routes pushed from VPN server are not 
excluded with Android 5.0.2.

@9 I can at the moment not reproduce the behaviour. Care to share the whole 
log, or at least the configuration pushed to the client?
