Unable to connect to Internet anymore once setup VPN server

Hi,

After I have setup a VPN sever on the Windows 2003 Server, I found that I
cannot connect to internet anymore (ex. Browsing with IE or getting Windows
Update) but the VPN server function is work fine. The local network
resources is still available but the internet function is not. Just want to
know is it the behaviour of VPN server ? Also, similar in the client
computer, once I connected to the VPN server, the internet function is also
disabled. But if I disconnected the VPN connection, every thing resume Okay.

Can anyone help me to solve these problems
Thanks

BTW, here is some information of my settings :

In the VPN server (Windows 2003 Server Standard Ed),
I have 3 NIC in which :
1. A fixed IP assigned from my ISP (ex 218.103.a.b) for
connection from remote client from the internet,
2. A internal IP (192.168.42.c) to connect to local network and,
3. A internal IP (192.168.1.d) to connect to another local network

IN the VPN client (I have tested from a remote site)
There is only 1 NIC and the IP is manually type (192.168.16.e)
( When the VPN connection is established, I can use all the remote server
resources in 192.168.42.f and 192.168.1.g from my remote client PC)

I'm not sure of where to configure this in Windows, or if you can configure
it. I use Cisco VPN and I have "split tunneling" turned off for the simple
fact that I don't want users using VPN on their home computers while
accessing a malicious website. That website would then have a path through
their computer to infect my domain.

This is the default settings for the security reason and all traffic except local should go to the remote gateway. You may have your administrator to help you to access the internet. If not, another option is changing the default gateway.

Bob,

You should be able to access the internet still on the remote client
computer by changing this setting.

Right click My Network Places and select Properties. Right click your VPN
connection and select Properties. Click the Networking tab at the top. Select
the Internet Protocol (TCP/IP) from the box and click Properties below it.
Clcik the advanced button. Finally de-select the "Use default gateway on
remote network". Click OK, OK ,and OK.

Now you should be able to acces the internet and items on your VPN.

There is a way around having the problem on your server as well but I'll
have to dig it up for you. I went through the same thing with a W2K server a
few years back.
