Whether a VPN connection has the "Use default gateway on remote network" option enabled has big impact on how network traffic from your machine is routed.
To make a long story short, do not ever shop at Letstalk.
I ordered two Motorola E815 cell phones from Letstalk on July 06, 2006 along with a Verizon family plan for my wife and I. The two handsets arrived on July 11. The two holsters I had ordered for the phones were too big although Letstalk advertised them as accessories for the E815.
After a week the battery of one of the phones started to show signs of a defect. Although it had been charged all night, it would only hold the charge for 10 hours without any calls made or received. A call to the Letstalk customer service number yielded an RMA number that was needed to send the phone back to Letstalk for exchange.
Being what's usually referred to as an early adopter, I was one of the first people to buy an 1st generation iPod. And I didn't even have a Mac. So I relied on a software called ephPod to upload and manage songs from my PC. That software still exists but is bug ridden and not as versatile as iTunes, which is what I use now with with my 40G 3rd generation iPod.
