Weird. My corp VPN, set up on the iPhone, works perfectly when I'm connected via WiFi. If I switch to 3G (on Rogers), it's dead to the world. Tried it on 2 iPhones, and on EDGE as well (also dead).

Anyone have any ideas?

You mean on Apple's end? Hmm... Never thought of that.

Hope not, though, because it would destroy tons of functionality. VPN over 3G is just essential to so many things that require secure connections.

Well, I went to the horses mouth. This article iPhone and iPod touch: Setting up VPN states the following "iPhone or iPod touch devices with iPhone 2.0 software or later can connect to VPNs that use the L2TP, PPTP or Cisco IPSec VPN protocols. VPN works over both Wi-Fi and cellular data network connections."

So you are correct it should work.

Rene, I have confirmed that it does not work over 3G. Haven't been in an EDGE area to try, but I would think it would fail the same. I'm on AT&T network. So are we looking at a bug here?

You can try by switching off the 3G toggle, that will mandate you use EDGE.

Same here with iPhone 3.0

Same problem here. Never could connect my company's VPN through 3G. Only WiFi. I am currently running iPhone 3.0 and it's the same.
Any thoughts?

:mad:

Based on this thread, looks like it was fixed in 2.2 but broken again in 3.0

This problem makes VPN useless to me. at home I may as well go to my laptop, but I need this most when I am away from all of my gear to get connected into work.

hopefully this will be fixed soon

is your vpn device set to limit incoming connections based on its source? what about NAT? does is allow connections from behind a nat device?

Works over wireless, which is typically NAT'd and I can connect and route just fine.

3G connects just fine, but does not route. Im not a network expert, but I would guess its something to do with AT&T's data network that is causing this to fail or some component of the 3.0 OS that is breaking down since it was 'fixed' at one point in the 2.2 OS.

I have the same issue with my 3GS Iphone, no problem to VPN and connect to the company's server using wifi, but no luck with 3G network, tried the Network Ping LT , Jaadu Romote Desktop and VNC LT, I don't think it is the application problem, might be something related to the IPhone software or
the 3G carrier.
I am using 3G network from Rogers in Canada.

(bump)

My understanding, at least with AT&T, is that there are two data plans: the regular $30 one, and the $45 "business" one that permits VPN connections over iPhone. If you go to the AT&T web site and log onto your account, you should be able to see that you can upgrade to the $45 version.

In any case, Jaadu VNC works great for me . . . . :)

This problem can be fixed by enabling NAT transversal over IPSec. If your router doesn't support it, you are out of luck. I had the exact same problem with a Cisco Pix. Good luck.

VPN not working on 3G or E

Sign into your PIX/ASA using ASDM. Go into configuration, Remote Access VPN, Network (Client) Access, IPsec Connection Profiles, IKE Parameters. There should be a check box "Enable IPsec over NAT-T". save your config & you are good to go!

Hello my friend. I suggest you to install Open VPN and all will work perfectly well. 3G/Edge or any other option. Software is open source.
Cheers

No VPN over Rogers 3G

I was told by a Rogers rep that VPN will not work over their 3G network. He could not tell me why. I can confirm that it does indeed not work.
