after VPN config, I lose internet access

Microsoft Windows server 2003

Specs: Windows Server 2003
I have been asked to set up VPN for a small standalone server at my office. I set up a test server with win server 2003 R2. After I install, I do have access to the Internet and I updated critical items from Microsoft Update center. Then I configure the server for VPN. After that, I lose Internet access. I'm at a loss as to why.
I know I'm a newb at server 2003, but I would like any insight into this.

I've never setup a VPN server on windows, but I have run into that type of an issue before.

Normally it's because when IPSec gets enabled on the interface, it will not pass unencrypted traffic unless you setup a policy to do so - so i.e., your internet traffic is blocked because you're not communicating w/ a secured peer.

Verify the "Enable security on the selected interface by setting up static packet filters" is DISABLED in your config, or try setting up some kind of IPSec policy to pass the unencrypted traffic (no idea how to do that in RAS, sorry)

You need a split tunnel. As said above when you establish VPN tunnel it puts you on a new Virtual LAN. Because of this you can not route to the Internet any more. By establishing a split tunnel you can fix this...

I am not sure if this is what you are looking for. I use CISCO routers which also needed split tunnels but it is different for CISCO.

I suspect you are only using one nic when you are supposed to use two for the rras vpn setup.
Not sure if that article which pertains to a workstation connection is applicable to a server.
