Problems with Windows 7 client from behind router

[klong]

I'm experiencing a strange problem that I'm wondering if anyone else has run into before.

I have a laptop with Windows 7 64-bit loaded on it. I had OpenVPN 2.1 on it and VPN would connect and work just fine if I connected my Blackberry directly to the laptop and connected with VZ Access Manager. However, if I hooked up my Blackberry to a Cradlepoint router, VPN would no longer establish. I tried different 3G devices, but no luck. Then I tried the laptop through other routers...linksys or whatever I could get my hands on. OpenVPN will NOT establish through the router.

But, here's the "gotcha". If I take this same cradlepoint router with the same 3G device and hook up a linux box behind it, it can establish the OpenVPN connection just fine. So, I KNOW the router will allow OpenVPN to go through it. It's not a port issue. I've compared the config files on the Windows 7 device with the one on the Linux device and they are identical other than some statements I found on the Internet that I added to see if it would fix the problem.

So, I know the router will pass OpenVPN for another device.
I know the Windows 7 device will do OpenVPN if connected direct to the Internet (no router).
It just will not work when I combine Windows 7 and a broadband router. The two work individually...just not together. (and again, I've tried more than one router...)

Has anyone else run into this before? Oh, and yes, I saw that 2.2 came out, so I tried upgrading to that and got the same results.

Thanks for any help or suggestions!

Look in the broadband device setup to see if there are any settings to allow simultaneous connections, or any settings on maintaining established connections regraless of network availability. I ran into a similar issue when using a sprint usb modem and smart view software used to establigh connections.
