Default Can't VPN when using BB as tethered modem

Please Login to Remove!

Hi,

Here is my 2nd post to the forums - hopefully someone has seen this before and has a solution.

I can successfully use the BB as a tethered modem (which is just great). All works perfect for getting internet access.

However, when I try to VPN into my office - it always fails.

It's a very simple PPTP server at the office end, and it definitely works with all the same settings (on the XP box) as I test with a dialup internet connection and all is perfect on that link.

So, I wonder what the story is with the BB service and not being able to get the VPN access.

Is there an easy switch that needs to be set? I'm with Optus (Australia).

VPN connection seems to start conversation but then fails (I can't get to see any logs from the router becuase it's quite a dumb little router). It's a Win Error 619.

Thanks for any help.

Not a VPN Expert but I would point more to the access software (Whatever your Telco gives you to connect) or a switch at the Telco that needs to be turned on. I doubt its a hardware problem.

I suggest you company invest in SSL-VPN. It is not expensive and will allow remote access over port 80. You are guarenteed remote capability from any web browser and Internet connection.

VPN's are typically connected via dial-up or DSL, etc., where you need either a phone number or IP address. I personally am not sure what the teethered modem gives as an identity but quite possible it's none of the 2 mentioned.

Yes. This is what I had thought...and wanted to see if someone here had the answer to this.

However, I do get an IP address once connected via tethered modem.

All Internet connections have an IP address. Some IP addresses are from a private class, while others are from a public class. Regardless of class all devices which have Internet access will have a IP address during the connection time (BB tethered modems included)

As an experiment while connected using your tethered modem visit whatismyi.com

Further information can be obtained form going to the command line of Windows Start-> run -> cmd -> "enter"

At the prompt type: "ipconfig/all" hit enter

Hmmm.....you may want to enable logging on your VPN client to see what kind of problems are occuring during the attempt. I am able to use the Cisco VPN client to connect to my Cisco PIX 515E firewall at home.

My corporate VPN works over my phone when used as a modem. It can be kind of sketchy, but it does work. We use SonicWall. I dont know much more than that.

Sonciwall is great!!! I resell and install them. An excellent firewall with enterprise class features. I like their SSL-VPN for remote access. It works great with an Internet connection, including tethere modems.

Good choice by your office.
