but has anyone ever used vpn to connect to a corporate network?

We use the tunnelling bit, but it isn't a proper VPN. We get to do that this year so I'll be able to tell from experience in a couple of months.

The main things the guys are looking at is authentication and speed and control of the gateways.

Very big topic.
Have a look at Checkpoint's VPN docs.

Quite a bit of FW-1 praising obviously, but also some very good explainations of how VPN works.

I use VPN a lot to log into the Intel corporate network. I have a cable modem at home and it works pretty well. It's almost as fast as the LAN at work. Using Exceed I can bring up Xterms. With compression I can bring up schematics and layout and work from home.

I set up the Nortel Contivity VPN for my company and it is very stable. In the most basic terms, we have a private and a public IP address, The private is of course the VPN device itself and the public goes out over the Internet (but is tied into the private). All the corporate network settings are on the VPN device itself, so when you come over the public IP from any ISP, it connects to the private IP and the VPN device which in turn connects you to whatever settings you give it, (which in my case, is the company's network backbone).
