Problems with Windows 7 client from behind router
Posted: Wed Jun 01, 2011 3:18 pm
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!
