If anyone from Juniper is watching this thread...
Has there been no discussion from Google on this topic? I cannot imagine that they would not have any interest in adding L3 VPN functionality, and if they did, certainly they would be talking to a big player like Juniper.
You would think so; but I don't know and doubt they have. The way the Android development group works is through seeing what people want. In order to do that, bugs/requests are filed and people vote on them to be added (see the link previously provided).
Where's problem, I see that they can:
but with root access, but it's not big deal.
Can You run it with root access to have network connect functionality?
You are correct that with root access it can be done; however, this is not a supported feature and requires a modified device in order to utilize the service. It is not expected that all users would know how, or desire to complete the activity, to root their devices.
To answer the other part of your question, no, L3 functionality is not available on a rooted Android through Junos Pulse.
Juniper could make the Android client like Windows Mobile and have client/server connectivity with SAM, specifically JSAM for Android. This is the way Sonicwall does their Aventail client for Android. It works great.
Interestingly there's an SSH tunnel application in the market which allows you to tunnel certain apps unrooted or the entire system (rooted) through the tunnel available in the market: http://lifehacker.com/5799888/ssh-tunnel-is-the-easiest-way-to-tunnel-on-your-android-device
It uses local-port mapping a-la JSAM. For now why not change the Junos Application to do this as well?
According to some recent posts on various forums (including a comment for Junos Pulse in the Android Market), L3 is now available in Junos Pulse for rooted users. I have not had an opportunity to test this yet. No it is not a solution for the typical users but would at least allow some of us to do some testing.
I now get prompted for root access when I start the application, but unfortunately still don't get an L3 tunnel (Droid 1). "Status" shows that VPN is "Disconnected" even though I can access the Intranet via the built-in browser. I do have a rooted phone.
Yeah, I just tried it on my rooted droid incredible and got the same thing. It asked me to allow root access then installed some vpn plugin and prompted me to reboot my phone. Following the reboot I am seeing the same thing as you. Ultimately RDP is what we are after.
